Michael Praeger (CEO)
Thank you, everyone, for joining us today. Joel Wilhite and I are excited to discuss AvidXchange's fourth quarter 2023 results. This now marks our 10th consecutive quarter of exceeding our revenue and adjusted EBITDA expectations. This past quarter was also a great reflection of executing the strategies we articulated during our Investor Day this past June in terms of balancing our growth and profitability objectives. Consistent with that, I am proud to announce that we delivered our first-ever $100 million-plus revenue quarter, along with a $15 million-plus adjusted EBITDA profit quarter, thereby posting a 36 on our Rule of 40 construct, which combines our revenue growth rate of 21%, along with our adjusted EBITDA margin of 15% for the quarter. Overall, we saw five main themes emerge over this past year that were certainly magnified in Q4. First, our continued strong customer engagement.
Second, our payment yield and supplier monetization strategies, which will continue to be our secret sauce, showing measurable results. Third, our margin expansion and cost efficiency strategies, delivering continued reductions in our unit costs and driving our gross margin expansion and resulting adjusted EBITDA growth. Fourth, our continued focus on investment in new innovation continues to drive competitive differentiation, increased value proposition for our customers, as well as create the long-term pathway to support our 20%+ annual organic growth rate objective. Lastly, our fifth theme being the resiliency of our middle-market customers, continue to show strong customer logo retention metrics exceeding 95% for our combined buyers and suppliers.
I want to highlight our continued high level of customer engagement right off the bat, because this success has been fueled first and foremost by our customer success, which in turn has been enabled by our value proposition that our product, technology, sales, and operation teammates have engineered and executed. Our buyer and supplier customers have validated this lasting value proposition by viewing us as their trusted partner to drive scale, workflow efficiency, along with confidence in managing billions of dollars worth of their invoices and payments over our two-sided network. We wouldn't be here where we are today and where we're headed in our growth and profit trajectory without them. As we seek to scale AvidXchange to be a billion-dollar revenue business in the coming years, it is still a vastly underpenetrated $40 billion addressable market opportunity.
Staying with the customer theme for a moment, let me just highlight the power of our value proposition with one of our buyer customers, Speedway Motorsports. Founded in 1959, Charlotte-based Speedway Motorsports is a leading player in motorsports marketing, promotion, and sponsorship, specializing in events like NASCAR and INDYCAR races. Similar to many of our clients pre-AvidXchange, Speedway was weighed down by a siloed, yet decentralized, paper-intensive accounts payable and payments process on its TRAVERSE accounting system. Combined with the newly adopted shared services business model, the level of complexity faced by Speedway was overwhelming.
In adopting our AvidInvoice and AvidPay solutions to streamline, digitize, and automate their invoice processing and supplier payments, Speedway was able to reduce monthly accounts payable work hours, shorten its month-end accrual process to approximately 30 minutes from a couple of days previously, while driving an estimated cost savings of over $300,000 annually. Spurred on by the success of invoice and pay solutions, Speedway broadened its lens to other AvidXchange products, such as AvidAnalytics, to review and analyze spending on a company-wide basis. Senior Vice President of Finance, Sarah Graffal, said it best, "You'll be amazed at how AvidAnalytics streamlines tasks and allows managers to see things in real time. It provides us with the ability to give our staff the reporting mechanisms and matrices they need on a timely basis. We are continuing to improve who we spend money with.
Looking at our purchasing data and being able to negotiate gives us buying power we can leverage. Those savings are then reinvested in other ways to enhance our at-track fan experience and empowering the finance team to focus on other business initiatives." The ability to create this type of lasting value for our customers, such as Speedway, is at the center of our innovation and product strategies. There's a deep product pipeline for 2024 that further builds on the value proposition we expect to further cement our leadership position in the marketplace. But before we lay out what new product offerings and platform innovations are in store for 2024, it's worth highlighting and reflecting for a moment on 2023, starting with our AvidXchange flywheel metrics.
During 2023, we increased the total number of buyer customers utilizing our accounts payable and payment automation software, excluding the decommissioned Create-A-Check product offering by 8.1% to 8,000 customers from 7,400 buyer customers in the year prior, driven by delivering a great AP automation software experience under gear one of our AvidXchange flywheel. Quick note on Create-A-Check. This offering was a non-strategic check printing solution utilized by our smallest customers to print paper checks on-premise. That was one of the several products acquired approximately 10 years ago via our Piracle Payments acquisition and not consistent with our focus on middle-market buyer customers, along with our focus on eliminating paper checks.
By contrast, we are still in single-digit penetration across our nine current verticals within our overall estimated addressable market of 435,000 middle-market companies just in the United States alone. In addition to our strong buyer-customer engagement, our supplier customer count was up 24% in 2023 versus 2022, and continues to be part of our secret sauce and our ability to monetize payments, which was fueled by innovative payment offerings and networking effects of buyers bringing their suppliers to our two-sided AvidPay network. The resulting addition of new buyer customers and supplier customers drove increased transactions onto our two-sided network and our overall spend under management under gear two.
Transaction volumes on our network exceeded 75 million, rising 7.4% year-over-year, with our total payment volume increasing by over 11% on a year-over-year basis to almost reaching $76 billion in 2023. This increase in total payment volume largely mirrored growth in our payment transaction count. The 7.4% year-over-year rise in spend under management to $230 billion tracks largely in line with the growth in our transaction volume. And given our growing transaction volume, we remain focused on maximizing our industry-leading e-payment monetization, which is our secret sauce, as we refer to it, by converting suppliers to one of our various forms of electronic payment on the AvidPay Network under gear three of our flywheel.
In 2023, e-payment monetized supplier count on the AvidPay Network grew by roughly 10% from the year prior, largely in line with our payment transaction growth rate. We believe this underscores the overall value proposition of our AvidPay Network for our suppliers. The sum of execution and growth across our AvidXchange business flywheel, encompassing buyers, suppliers, and transaction monetization, resulted in nice growth in our all-encompassing transaction yield metric, which was up over 12% to $5.05 per transaction in 2023, compared to $4.51 per transaction in 2022. In addition, in the fourth quarter, we reached a record high transaction yield of $5.45, which is up 13.8% over the same period last year.
We also ended the year with our Net Transaction Retention Rate at 101%, which has been impacted by the pressure of discretionary spend across the middle market as a result of the current macroeconomic environment, causing middle-market companies and their CFOs to be more cautious with their discretionary spend. As we bid farewell to 2023, I want to take a moment to reflect on the financial and strategic accomplishments of the year. 2023 was a year of demonstrable financial resilience and strategic advancement as we delivered both 20% revenue growth and adjusted EBITDA profitability. Driven by the impact of our various efficiency initiatives and scale of our operations, from resilience perspective, we delivered a healthy revenue growth, up 20.3% to over $380 million for the year.
This, in the face of ongoing macro choppiness, impacting transaction volume around discretionary spend in the areas of marketing, advertising, and professional services, which we were able to effectively counterbalance with continued yield expansion through our various innovation strategies with suppliers. Meanwhile, the pace of progress on unit cost reduction continued unabated through actions around standardization, automation, and sourcing, including numerous work streams utilizing artificial intelligence across all areas of our business. This enabled us to deliver solid execution on our unit cost objectives, driving gross margin expansion of 540 basis points to 69.4% in 2023, and we continue to be excited about the expected long-term impact on these unit cost reduction initiatives.
We also continue to focus on optimizing our resources in other functional areas as we mind our OpEx and investment discipline, which led to a swing of over $45 million in adjusted EBITDA profitability in 2023 over 2022. I'm especially pleased to say that we exited the fourth quarter with our first-ever adjusted EBITDA profit, excluding the contributions of float and political-related media revenues. And finally, we finished the year with a solid balance sheet, including a net cash position of over $374 million. The combination of our strong balance sheet, combined with our scaling profitability, provides us with significant optionality to continue investing in our targeted strategic initiatives, which we believe will drive shareholder value in years to come. On the strategic front, we believe we have positioned the business for greater success in 2024.
First, we inked a key transformational accounting system partnership with AppFolio, our biggest partnership ever, with a top provider of solutions focused in the real estate multifamily vertical, with roughly 19,000 customers, potentially half of those that meet our target customer profile. Also, in 2023, we leveraged another accounting system partnership with a cloud-based accounting solutions market leader, M3, as a springboard into our new hospitality vertical with our M3 CoreSelect integration, which went live in November of 2023. Both of these integration partnerships should begin to contribute starting in the second half of 2024. Second, our top-of-funnel buyer sales opportunities increased around 15% in the 12 months of 2023 over 2022, demonstrating strong interest and engagement with buyers.
Third, we advanced our payment product portfolio with several significant innovations, including the launch of our new payment modality, such as our lien waiver payment modality for the construction vertical. Fourth, we released our much-anticipated digital invoice financing product, Invoice Accelerator 2.0, in October 2023, now being branded as Payment Accelerator. And finally, we continue strengthening our executive talent team with key additions on our revenue and product teams with James Sutton as our Chief Revenue Officer and Doug Anderson as our Chief Product Officer, while elevating Dan Drees and John Feldman to the roles of President and Chief Operating Officer, respectively.
Overall, I am very pleased with the leadership team that we have built and feel that we're well-positioned as we focus on executing the next chapter of our journey to attain our goal of reaching $1 billion in revenues in the coming years. With those highlights, I want to spend the remainder of my remarks on our product and platform innovation initiatives in 2024, both of which fall under gears three and four of our AvidXchange business flywheel. We're excited about the development of our new spend management platform. Currently, virtually all of our buyers' customers' invoice-based expenses are processed through our platform as we are the system of record for our customers' invoice transactions, with the remainder of the non-invoice-based expense transactions being processed outside of our system, either through manual processes or through other third-party software applications.
Our new spend management offering will tackle those remaining non-invoice expense transactions. However, our approach to spend management is highly differentiated and purpose-built for the middle market. Whereas traditional spend management programs are focused mainly on travel and entertainment expenses, ours will be focused on managing functional team-level procurement first, along with managing travel and entertainment expenses for our customers. It will also be managed at the point of purchase with real-time syncing, coded, and approval status. And most importantly, our spend management module will be highly integrated with our core accounts payable invoice suite, leveraging our GL coding and approval workflow capabilities, along with having centralized expense and data reporting for all of our customers' expenses in one platform; both invoice and non-invoice transactions, which is extremely important in the terms of driving adoption, cross-selling, interoperability, and user experience.
We expect that our spend management offering should result in high attachment rates and nonlinear growth contributed, while driving higher TPV yield in future years. There are lots of different use cases for the product. One, for instance, could be a property manager employing the card to purchase a faucet, and the transaction immediately synchronizes with our AP solution. This, we believe, will provide finance leaders a holistic view of virtually all expenses that occurs across the company, displacing either personal cards without proper controls or petty cash. With our offering, this ensures that their spend will be in compliance with each customer's business rules, including budgets and expense categories, as we monetize transactions from both virtual and physical card volume. The platform is planned for initial rollout with select customers in the latter half of 2024, and then scaling in 2025.
2024 is also the year when we plan to ramp key functionality of our new payments platform, which is the foundation of our AvidPay Network. This is an effort that has been part of our product roadmap for the last several years. We believe the new capabilities of our payments platform are transformational in the way our customers experience managing their payments and the way we operate. A critical dependency in our ability to advance e-payment adoption is to create new payment modalities through real-time configuration, combining pricing terms, speed of settlement, access to remittance data, and payment acceptance automation, as opposed to software development dependencies. Our new payments platform is designed to unify disparate systems and operational processes within a single platform to deliver the best supplier and buyer customer experiences.
With our new platform, we'll be able to be well-positioned to guarantee delivery of critical payments on time, despite potential delays of invoice approval by our buyer customers. Second, we believe that we can expand our payment footprint to non-invoice-based transactions such as loan, leases, and various other tax payments. Third, we'll be able to create new payment products real time, based on speed, remittance data, pricing, automation, et cetera, and therefore drive greater e-payment adoption for our buyers and suppliers. And finally, with our new payment platform, we believe we will not only be able to enhance revenue through greater yield, share of payments wallet, but also improve the cost structure in both hard and soft operational costs, including the reduction of paper check payments. In closing, we believe we are well-positioned for 2024.
With our 2023 building blocks in place, the five themes which drove our success in 2023 will continue to bear fruit for us in 2024 and beyond. Coupling our industry leadership with highly differentiated foundation for our strategic and operating roadmaps in 2024, in particular, the success we continue to achieve in reducing unit costs and leveraging operational expenses, we believe we are setting up for delivering on our Investor Day targets. To be sure, we'll be tested along the way, given the macro volatility, and remain focused on controlling those elements of our business that we can directly control ourselves.
But with the strategy and execution rigor we have set in motion and are delivering on, we believe we're well-positioned to drive impactful value for our customers, create future growth opportunities for our team members, and unlock significant long-term value for our shareholders. With that, I'd now like to turn the call over to my partner, Joel Wilhite.
Joel Wilhite (CFO)
Thanks, Mike, and good morning, everyone. I'm pleased to talk to you today about our fourth quarter 2023 financial results, which reflect continued execution of our growth strategies amid continued macro uncertainty. Overall, we delivered another quarter of healthy year-over-year financial performance. Relative to the implied fourth quarter 2023 business outlook and adjusting for float and political, fourth quarter revenues came in higher due to payment and software yield expansion, driven by ongoing e-pay conversion. That, together with higher gross margins driven by higher revenues, progress on unit cost initiatives, software and pay yield expansion, as well as sustained expense discipline, led to significant adjusted EBITDA outperformance. It's worth noting that we delivered our first-ever adjusted EBITDA profit, a major milestone, even after stripping out float and political.
We believe that by crossing this profit chasm on a core basis underscores not just the power of our business model and disciplined execution, but also our confidence in achieving our Rule of 40 target by 2025. Now, turning to year-over-year results. Total revenue increased by 20.8% to $104.1 million in Q4 of 2023 over the fourth quarter of 2022. More than three quarters of the revenue growth was driven by the combination of the addition of new buyer invoice and payment transactions, coupled with software and pay yield expansion. The remaining revenue growth this quarter was driven by higher year-over-year float revenue, net of year-over-year decline in political revenues.
Our strong revenue growth also resulted in total transaction yield expanding to $5.45 in the quarter, up 13.8% from $4.79 in Q4 of 2022. Of the 13.8% increase, roughly three quarters of the increase was driven by pay and software yield, coupled with transaction mix skewed toward payments. The remainder was due to the flux between float and political revenues. Software revenue of $29 million, which accounted for 27.9% of our total revenue in the quarter, increased 10.1% in Q4 of 2023 over Q4 of 2022. The increase in software revenues of 10.1% was driven by growth in total transactions of 6.1%, which continues to be impacted by macro conditions, with the balance driven by growth in certain subscription-based revenues.
Payment revenue of $74.2 million, which accounted for 71.3% of our total revenue in the quarter, increased 25.5% in Q4 of 2023 over Q4 of 2022. Payment revenue reflects the contribution of interest revenues, which were $13.7 million in Q4 of 2023 versus $5.8 million in Q4 of 2022. Recall, our year-ago payment revenues also included contribution from political media revenue. Of the 25.5% increase in payment revenues, more than three quarters was driven by a combination of an increase in pay yield expansion and payment transaction volume increase of 9%, with the remaining portion driven by the aforementioned flux between interest and political revenues.
On a GAAP basis, gross profit of $67.3 million increased by 34.8% in Q4 of 2023 over the same period last year, resulting in a 64.6% gross margin for the quarter, compared to 57.9% in Q4 2022. Non-GAAP gross margin increased 650 basis points to 71.4% in Q4 of 2023 over the same period last year, and was driven mostly by unit cost efficiencies and yield expansion. Now, moving on to our operating expenses. On a GAAP basis, total operating expenses were $79.5 million, an increase of 1% in Q4 2023 over Q4 of last year.
On a non-GAAP basis, operating expenses, excluding depreciation and amortization, increased 2.6% to $58.8 million in the fourth quarter of 2023 from the comparable prior year period. On a percentage of revenue basis, operating expenses, excluding depreciation and amortization, declined to 56.5% in the fourth quarter of 2023 from 66.5% in the comparable period last year. The year-over-year percent decline largely highlights the significant operating expense leverage, particularly across G&A, sales and marketing, as well as R&D to an extent, even after stripping out the contribution of float. I'll now talk about each component of the change in operating expenses on a non-GAAP basis.
Non-GAAP sales and marketing costs decreased by $1.1 million, or 5.7% to $70.5 million in Q4 of 2023 over Q4 of last year, which was driven by a combination of efficiencies in marketing spend, a decrease in performance-based compensation, and realignment of resources, coupled with a delay in timing of certain investments. Non-GAAP research and development costs increased by $2.6 million, or 13.1% to $22.1 million in Q4 of 2023 over Q4 of last year. The increase was due to continued reinvestment in our products and platform, including spend management, pay offering, and payment accelerator. Non-GAAP general administrative costs remained unchanged at $19.2 million in Q4 of 2024 versus Q4 of last year, due to leveraging public company costs across a larger revenue base.
They continue their annualized downward progression as a percentage of revenue, as we indicated during our Investor Day. Our GAAP net loss was $4.5 million for the fourth quarter of 2023, versus a GAAP net loss of $25 million in the fourth quarter of 2022, with the reduction in losses driven by a combination of strong revenue flow-through and expense control, leading to lower operating expenses, coupled with higher interest income and lower interest expense due to reduced borrowing costs and partial debt paydown. On a non-GAAP basis, our net income in the fourth quarter of 2023 was $9.4 million versus a net loss of $7.5 million in the same year-ago period, a $16.9 million positive swing from last year, driven by the aforementioned factors.
Similarly, on a non-GAAP basis, Q4 2023 adjusted EBITDA was a $16.9 million positive swing from an approximately $1.3 million loss in Q4 of 2022. Turning to the balance sheet for a moment, I want to touch on a few key items. We ended the year with a strong corporate cash position of $451.6 million of cash and marketable securities against an outstanding total debt balance of $77.3 million, including a note payable for $13.9 million. We had $30 million on our credit facility undrawn at year-end. Corporate cash, meanwhile, was split roughly two-thirds among money market funds, commercial paper, and time deposits, with the remaining third in deposit accounts.
The weighted average maturity on corporate cash was roughly 10 days, while the effective interest rate on our corporate cash position for the fourth quarter was roughly 5.25%. Customer cash at quarter end was approximately $1.6 billion, with an interest rate of roughly 5% for the quarter. The jump in customer cash was primarily timing related to funds in transit, along with shifts in calendar days between weekdays and weekends of receipt and disbursement of that cash. Turning to our 2024 business outlook, we expect total revenue for the year to be in the range of $441 million-$447 million. Based on the midpoint, we expect approximately 47% of the 2024 revenue distribution to be in the first half, versus 53% in the second half.
Our 2024 revenue outlook reflects the revenue impact of decommissioning our on-premise check printing software, Create-A-Check, the buyer customer base, and revenue contribution, of which was roughly $1,401 million in 2023, respectively. The outlook also incorporates approximately $44 million of interest revenues from customer funds versus roughly $41 million earned in 2023. Also, we anticipate political media revenue contribution of approximately $9 million, given that this is our first presidential cycle under FastPay. Recall, we acquired FastPay in 2021. For context, in 2022, during the midterm election cycle, the political arm of FastPay generated roughly $8.5 million in revenues. Similarly, we expect non-GAAP adjusted EBITDA profit ranging between $67 million and $71 million for the year.
With that, I would now like to turn the call back over to the operator to open up the line for Q&A. Operator?
Operator (participant)
We will now begin the Q&A session. To ask a question, you may press star, then one on your touch tone phone. If you were using a speakerphone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw your question, please press star, then two. We ask that you please limit your questions to one question. At this time, we will pause momentarily to assemble our roster. The first question comes from Ramsey El-Assal with Barclays. Please go ahead.
Shray Gurtata (Assistant VP and Research Analyst)
Hi, this is Shray for Ramsey. Thanks for taking my question. I was just wondering if you could comment a bit more on the magnitude of macro pressure that's factored into the guide. Is it contemplating any further deterioration, or, or is it more of a steady state?
Joel Wilhite (CFO)
Yeah, great question. Just to be real clear, the sort of macro dynamic that's causing buyers to sort of limit their spend, that subset of discretionary spending has really continued consistently through the year, even to now. Our guide contemplates no change. You know, we're hopeful that that turns around, and we expect those types of spending can't be put off forever, but our guide contemplates continued macro conditions that we experienced in 2023.
Shray Gurtata (Assistant VP and Research Analyst)
Got it. Very helpful. Thanks.
Operator (participant)
The next question is from Craig Maurer with FT Partners. Please go ahead.
Craig Maurer (Director of Research and Managing Director)
Yeah, hi. Thanks for taking the question. Wanted to ask, you know, if you can characterize your assumption on political spend. You said $9 million in political revenue in 2024. In the past, you've outlined that you see 30%-35% of all political advertising spend and forecasting a $10 billion spend cycle. So, you know, I'm trying to understand the level of conservatism built into that number. Thanks.
Joel Wilhite (CFO)
Yeah, great question. You know, we are baking $9 million into the guide. We've pointed out that this is our first presidential cycle with FastPay, and so, you know, it's possible that there's some upside to that in the back half. You know, it's a little less predictable than our core, you know, fundamental recurring business, and so we felt like, you know, $9 million was a prudent guide.
Michael Praeger (CEO)
Yeah. Hey, Craig, I think it's... This is Mike, and I think it's a great question because, as Joel said, this is our first presidential cycle, you know, ourselves managing through it. And I think, you know, we usually take kind of a cautious approach to new things, and this is a good example of that. You're right, we do control about 35% of all the media-related payments in the industry. But one of the things that's inherited in the industry, although we have the leading market position, is there's not a lot of visibility and lead time to when, you know, particular advertisers may receive, you know, orders for, you know, advertising placement. A lot of it is very, you know, last minute, and with short lead time.
There's not a lot of visibility we have to it. That leads us to, you know, that dynamic, combined with it's our first rodeo through the political cycle, just take more of a cautious approach to it.
Craig Maurer (Director of Research and Managing Director)
Could you perhaps talk about the take rate in political versus the rest of the business?
Joel Wilhite (CFO)
I think what we've said in the past is it's, you know, it's slightly, but I wouldn't say meaningfully higher. It is a little higher, given a higher mix of-
Craig Maurer (Director of Research and Managing Director)
Yeah
Joel Wilhite (CFO)
... digital payment acceptance.
Michael Praeger (CEO)
... And one of the, just as a flavor there, the reason why we have our, you know, leading position in political is that we've been on the forefront of that conversion of, and creating specialized payment types for media-related payments in moving from paper check to electronic because of the short lead times. So certainly, you know, our innovation focus on, you know, different payment modalities for media, has been kind of a key component of our, you know, our market position there.
Craig Maurer (Director of Research and Managing Director)
Thanks. I appreciate the color.
Operator (participant)
The next question is from Dave Koning with Baird. Please go ahead.
Dave Koning (Senior Research Analyst)
Yeah. Hey, guys, thanks so much. Congrats. And maybe for my main question, your dollars of core payments growth was about the strongest we've ever seen, and you mentioned it was driven a lot by yield, more e-pay, shift to e-pay. But within e-pay, are there certain types that suppliers are asking for more? Like, is VCC just as a percentage, like, drawing more and more? And if that's the case, maybe what's kind of driving all that?
Joel Wilhite (CFO)
Yeah, no, thanks. Great question, Dave, and really strong kind of yield quarter and even, you know, excited about the things we have to come from a yield perspective. But to answer your question, like we're, you know, we're continuing to sort of march down the path of taking checks out of the system, moving towards digital. We're also, you know, the discipline around operating is creating opportunities through just, you know, reducing exceptions, better offshore management of processes. Those things we talk about that drive unit costs down also give us yield opportunities as well.
Dave Koning (Senior Research Analyst)
Gotcha. Thanks. Maybe just a quick follow-up. Interest revenue was up a lot sequentially, 25%-30%, with rates being, I think, pretty stable. Was there something to the amount of dollars you're holding, and is that sustainable?
Joel Wilhite (CFO)
Yeah, no, it's a great question. So you'll notice, you know, we finished the year with about $1.6 billion of customer funds on the balance sheet, so a nice uptick there, and it was really that that drove the rate in the quarter. So it's about $13.7 million float revenue in the fourth quarter. There's the drivers are really the timing of the funds moving between buyers and suppliers, including things like how much is in transit at a particular, whether it's a weekday cutoff or a weekend cutoff. So that's really, you know, sort of an expansion in customer funds as we finish the year is what drove float.
And I would suggest, and what is historically kind of consistent, is that customer funds will level off over the course of the first quarter in 2024.
Dave Koning (Senior Research Analyst)
Gotcha. Thanks, guys. Congrats.
Joel Wilhite (CFO)
Thank you.
Operator (participant)
The next question is from Andrew Bauch with Wells Fargo. Please go ahead.
Andrew Bauch (Director of FinTech Equity Research)
Hey, guys. Thanks for taking the question. Just looking at the incremental margins ex float, I mean, really impressive. It looks like based on this guide, 60%+, and relative to our estimate of, I think, 29 ex float in 2023. So I'm just trying to get, understand the sustainability of that. And I know that you guys have been making efficiency investments in your cost of goods sold line, but trying to weigh that versus what you've seen on the e-pay front. Just trying to figure out the magnitude of upside there.
Joel Wilhite (CFO)
Yeah, I mean, let me just kind of remind you. I would just take us back to the targets that we set out at Investor Day. We said we would, you know, be in the 72%-75% gross margin range in 2025. And we've had great, you know, kind of continued margin expansion by doing the things that we've been talking about consistently, since the IPO. And so we said that the way we would get there is a mix of yield, and unit cost efficiency. Yield, call it 2/3, and unit cost, call it 1/3, though not necessarily linear. And we're just kind of continuing to execute that plan. And so if you strip out float, in the fourth quarter, that, you know, that's a 67% gross margin.
So, you know, six good solid points up year-over-year, but, you know, a ways to go, and we've got the levers and the opportunity to do that, both on yield and unit cost.
Michael Praeger (CEO)
Yeah, and, and Andrew, I'd say, you know, I can simply look at it. It's really, you know, the blended combination of two things. You know, that efficiency, as Joel says, driving yield. And, and certainly, you know, AI has been a nice, component of that, you know, expansion as well as, and, we continue to see that, you know, scaling, you know, as we go forward. I think, you know, as we've talked about, you know, we have, you know, roughly about a dozen different initiatives across the business related to AI, both, you know, customer facing and, you know, kind of focused internally. And then the second piece, is on the yield.
And that's where all our strategies and innovation related to, you know, monetization strategies, new payment modalities, our straight-through process, you know, capabilities with suppliers, all those type of things are, you know, taking hold. And so I think, you know, the combination of those two and, so, we believe we're, you know, in an early days of, you know, continuing to drive, you know, that overall, you know, margin of expansion, and expect that to continue over time.
Andrew Bauch (Director of FinTech Equity Research)
Yeah, that makes a lot of sense. If I could just squeeze one more in. In the press release, you say the 2024 outlook reflects accelerating revenue growth. You did 20% in 2023, and the initial guidance for 17. Can you just clarify, you know, what that accelerating revenue growth language means?
Joel Wilhite (CFO)
Yeah, you bet. We're addressing ex float and political.
Andrew Bauch (Director of FinTech Equity Research)
Great. Thank you.

The next question is from Darrin Peller with Wolfe Research. Please go ahead.
Darrin Peller (Managing Director and Senior Analyst)
Hey, guys. Maybe we just start off. I just want to ask about the supplier growth. I think it was 24% in 2023.
... which I thought was a great call-out. And just if you could remind us how that compares to the change in prior years, the general timing for suppliers to be more monetized using, you know, different methods, whether it's Invoice Accelerator, AvidPay Network, et cetera. And then I guess as a follow-up to that, I know your goal is potentially going up to 70% monetization of your transactions over time. And I'm assuming that obviously is highly correlated with the supplier network growth and the implementations of different work there. So maybe help us with a split, if you can, on the kinds of tools between AvidPay Direct or virtual card or other kinds of payment modalities would be great. And thanks again, guys. Nice quarter.
Michael Praeger (CEO)
Yeah. Hey, thanks, Darrin. Well, that, that was a, you know, kind of a multifaceted question, so let me kind of, you know, chip away at it. So first of all, you know, the supplier growth out, you know, question. Yeah, we're super excited. You know, we broke the 1 million threshold and, you know, ended the year at 1.2 million suppliers on the network. That is, that 24% growth is, is consistent to what we've seen in past years. So, you know, so we feel like that we're at a, you know, continue to be at a nice rhythm in terms of growing the network on the supplier side. The... And, and, and we see kind of a consistent mix of, you know, enroll suppliers in terms of payment modalities.
So the two big buckets, you know, categories that we have are, you know, those that accept a form of virtual card, and I'll come back to that in a second. The second one is a form of our AvidPay Direct, which is our ACH Plus offering. You know, back 10 years ago, we had one payment modality in each of those buckets. Today, in virtual card, you know, we have about 12 different payment modalities, where we have these, you know, partly because of our, you know, deep partnership with Mastercard, our ability to manage multiple forms of interchange.
And the combination, what we do is, we use the combination of price, which is interchange structure, combined with speed of payment, combined with the date of remittance and reconciliation data, and then lastly, combined with a level of straight-through process. And so those are like, you know, four variables that we have within a payment modality, and different levels within those four, you know, create different payment modalities across virtual card that, you know, will allow, you know, suppliers that maybe don't have acceptance of card from, you know, across the industry, to be able to, you know, accept a card and stay in a straight-through process with high levels of reconciliation data provided directly to them. So it's a non-human touch accounts receivable function on their side.
Those are, you know, all examples that we're using to, you know, continue to add suppliers to the network. On the flip side, on the AvidPay Direct, we're doing really the same thing, except settling through, you know, ACH, but again, combining, you know, speed of payment, different price points, you know, different levels of remittance data, along with different levels of straight-through process. And so, you know, I think you ended with, you know, kind of the reference to, you know, long term, we expect that we think we can take, you know, monetized payments to about 70% of transactions. And, you know, we, we still believe that. But again, it's not gonna be on, you know, one particular payment modality that kind of saves the day.
It's, you know, lots of different pay modalities combining different levels of, you know, those four factors that we continue to believe is the secret sauce.
Darrin Peller (Managing Director and Senior Analyst)
That makes sense, Mike. Thanks for the comment. I'll turn it back to the queue.
Michael Praeger (CEO)
Yeah.
Darrin Peller (Managing Director and Senior Analyst)
Thanks again.
Michael Praeger (CEO)
Thanks, Darren.

The next question is from Jamie Friedman with Susquehanna. Please go ahead.
Jamie Friedman (Senior FinTech and IT Services Research Analyst)
Hi, good morning. I wanted to ask, Michael, about the, the spend and expense management product launch. You had alluded to that, I believe, last quarter. And, you know, it seemed like you were pretty optimistic about the opportunity there. So any, context on that, or timing, or significance would be helpful? Thank you.
Michael Praeger (CEO)
Yeah, thanks, Jamie. Yeah, I'm glad you asked that question. Certainly, you know, in the past, I was always excited, you know, to talk about our Invoice Accelerator, now Payment Accelerator offering, and now that that's in the market, you know, I'm spending a lot of energy on our, on our spend management, you know, upcoming, up-and-coming platform. And so, yes, we expect it to be, you know, released to initial customers, you know, later in this year, but really have, you know, start having an impact in, you know, in 2025, and beyond.
However, you know, the reason for my excitement around it is when you think of, you know, all the transactions that we manage today, we do a really good job of managing close to 100% of all the expense transactions that have an invoice, for our customers, because we're the system of record for all their invoice-related expenses and directly, you know, are the, the feed to their general ledger, get things paid. However, we think that we're managing overall, in terms of a customer's expenses, probably in the 85% range of a customer's expenses relate to an invoice, and then you have 15% that kind of fall outside that, which occur into, say, travel, entertainment expense, or other, you know, kind of functional team level expenses that they need to make in terms of immediate payments...
The mission of our spend management platform is to capture as much of that remaining 15% of the spend that a customer has that haven't been our platform. But the real thing that makes it unique to AvidXchange is, which I know our customers are really excited about, is now having all their financial expense data in one platform for reporting. So one of the, you know, the thorns in the side of lots of the CFOs of our customers is, Mike, you know, we have 85% of our expense data. That's great for reporting, but then we have to, like, piece together the remaining 15%. It's either a manual process or in third-party, you know, other third-party applications that are, you know, not as well integrated to our general ledger.
And it'd be great just to have one place that we can do, you know, go and have all our expense reporting to, you know, better run our business. And so that's the mission that we're on, and we think, the spend management product is, you know, long term, gonna give us that capability and provide just a, a really, you know, great increase in the value proposition to our buyer customers.
Jamie Friedman (Senior FinTech and IT Services Research Analyst)
Great. Thanks for the context, Mike. I'll drop back.

The next question is from Bryan Keane with Deutsche Bank. Please go ahead.
Bryan Keane (Managing Director and Senior Equity Analyst)
Hi, guys. Congrats on these results. Wanted to go back to the revenue acceleration that you're expecting this year. I know that's ex-float and ex-political. Can you just talk about a couple of the drivers there? And then what might make this guidance conservative or any risk to the top line number? And then just lastly, on EBITDA, coming well ahead of our expectations and consensus for this year. Any thoughts on 2025, the 20%+ EBITDA margin? Does that also mean that you're maybe running ahead of kind of original targets for 2025 on EBITDA? Thanks.
Joel Wilhite (CFO)
Thanks, Bryan. Yeah, let me just kind of take those in order. So a couple of things we're excited about in the guide, particularly in the back half, are yield-driven acceleration associated with, we've talked already about kind of beginning to see that curve and Payment Accelerator. Also, in terms of the, you know, kind of opportunities to offer increasingly more payment methods, and so to accelerate the digital acceptance there. We also, remember, have, you know, M3 and AppFolio that, that, you know, are sort of still ramping and so could, could contribute from a volume perspective. So feel good about kind of how things are setting up in the back half. Your second question is like, if we were surprised to the upside, what would that look like?
I think, you know, we, we already touched on the approach we took in guidance for the political cycle. I think the next thing I would point to is those, you know, new pay methods. Like, we're really excited about having invested in those, and those could potentially, you know, move the needle for us, not to mention Payment Accelerator. All that said, keep in mind the macro backdrop, right? We are continuing to guide and project, assuming no change, and we're hopeful that there's change, but of course, that's not contemplated in the guide. And then the final question on EBITDA. Again, really kind of proud of how we finished the year and setting ourselves up to, you know, to sort of turn the profitability corner and be meaningfully profitable in 2024.
Your question about 25, what I would say is that even in, even with the macro backdrop that exists today, we feel like we've got sort of all the levers available to us. As gross margin continues to expand, again, we see additional yield and unit cost opportunities to do so, plus the leverage that you're seeing in operating expenses. So we feel good about that Rule of 40 target for 25.
Bryan Keane (Managing Director and Senior Equity Analyst)
Awesome. Thank you, guys.
Joel Wilhite (CFO)
Thank you.

The next question is from James Faucette with Morgan Stanley. Please go ahead.
James Faucette (Managing Director and Senior Equity Research Analyst)
Great. Thank you very much. I just wanted to ask generally, most of my questions have been answered in terms of where you're at right now, but wanted to ask in terms of M&A. You guys have historically done a good job finding opportunities to add additional, either end customers and markets or, capabilities to the platform. And so just wondering how you're thinking about that, especially as your profitability improves, how should we think about capital allocation M&A within that? And are you seeing good opportunities in pipeline? Thanks.
Joel Wilhite (CFO)
Maybe first on capital allocation, then Mike can mention context of what we're seeing in the M&A pipe. I think, you know, we are, again, sort of turning profitable, looking at sort of meaningful free cash flow in our future. I would say from a capital allocation perspective, M&A is really interesting to us, and in terms of our balance sheet, kind of looking at, you know, all the options that we have available to us.
Michael Praeger (CEO)
Yeah, maybe a little bit of a pipeline. We think it's, you know, long term, it continues to be, you know, a part of our overall, you know, kind of growth expansion playbook. We think in addition to, you know, kind of our 20%, you know, kind of growth mantra that we, you know, expect to deliver, you know, consistently on a long-term basis, that there's an inorganic growth, you know, lever that we can add to that, you know, should we find the right opportunities. So I think we're very focused on, you know, we're talking to lots of participants. You know, typically, they're smaller companies that are, you know, in the different, you know, nine verticals that we're in.
We also have, you know, some, you know, targets in terms of new verticals that we'd look for acquisitions in. And we're having lots of conversations. We, you know, I think, are still, you know, have not seen the kind of private market valuations reflect, you know, those that are at the public company level yet. And so I think, you know, we'll continue to, you know, be, you know, cautious. However, when the right opportunities present themselves, certainly, you know, with our balance sheet and capabilities, we are in a great position to execute these. I think the core playbook, however, is around vertical market expansion. We feel really good about our product capabilities, and so that wouldn't be kind of a key focus for us.
It'd be more, you know, continue to grow beachhead of customers within the nine verticals that we're in, as well as use it as an opportunity to expand those verticals even further.
James Faucette (Managing Director and Senior Equity Research Analyst)
Great. Thank you.

The next question is from Tien-Tsin Huang with JPMorgan. Please go ahead.
Tien-Tsin Huang (Senior Analyst)
Hello, good morning. Really good results here. Just on the outlook, I wanted to ask if new product contribution is a meaningful or measurable contributor to fiscal 2024 here relative to your past initial guides? So just new product contribution.
Joel Wilhite (CFO)
Yeah, Tien-Tsin, great question. I think probably what I would just add is on the supplier side. We talked about the payment, you know, opening up new payment modalities. But otherwise, you know, kind of all the products in the back.
Michael Praeger (CEO)
Yeah, and I think, you know, even when we think of the new products that we have, you know, Payment Accelerator and then spend management, as I alluded to earlier, those really aren't, you know, it really factors in terms of executing this year. They really set us up nicely for 2025, 2026 and beyond.
Tien-Tsin Huang (Senior Analyst)
Got it. So really more build up the momentum, and then we'll feel more of that in fiscal 25. Okay, got it. Just on the. Just thinking about, you know, the. I know you got a lot of questions on FastPay and visibility. I'm just curious, when will you get closer visibility on that? Is it really gonna be in just in that third quarter in terms of how real or conservative that outlook that you're setting up will be? I'm just curious how quickly you might see that, what the lead time would be based on the past.
Michael Praeger (CEO)
Yeah, remember, based on the past is the key word, this is our first political cycle. So, in a non-presidential cycle, I should say. In the kind of interim cycles that we do have some experience with, you know, we saw you know, a smaller level or lower level activity occur, you know, earlier in the year, and then obviously it builds up, and Q3 is the monster quarter for it. And so I think, you know, we're taking a cautious approach and expecting a kind of a similar build to the year as we've seen in the non-presidential cycles.
But we're probably as, you know, as anxious to, you know, to see how everything falls out as you are. We just, you know, take a cautious approach to it, but we think we've set ourselves up really nicely in terms of our market positioning. We've added some really nice political customers, you know, since the last cycle and really like our industry positioning and being the leader in political payments.
Tien-Tsin Huang (Senior Analyst)
Yeah. No, it seems set up well. Thank you both.
Michael Praeger (CEO)
Thank you.

The next question is from Alex Markgraff with KeyBanc Capital Markets. Please go ahead.
Alex Markgraff (VP and Equity Research Analyst)
Hey, guys. Thanks for taking my question. Just one for me. Quickly on some of these partnerships, AppFolio, M3, you mentioned the sort of contribution in the second half of 2024 starting to show up. I'm just curious, is that sort of the time to benefit we should start to think of as you sign more of these? Or are there some, you know, early learnings from the first couple that might kind of accelerate that time to revenue as you add more partners here?
Michael Praeger (CEO)
Hey, so first of all, you know, we're, you know, we're super excited about, you know, our, you know, overall sales motion. You know, you know, I'd say the partnerships is certainly, you know, exciting. I'll talk about in a second. But remember also that, over the last year, it's been a phenomenal year in terms of building talent in our go-to-market strategies. You know, the addition of James Sun as our Chief Revenue Officer earlier last year, and then, the addition of Doug Anderson later in the year on, as our Chief Product Officer, you know, that combination is really powerful in terms of, you know, how we, you know, kind of really, you know, accelerate, you know, that organic growth, you know, kind of formula.
And then executing on the partnerships is a key piece of that. So I think, you know, like some of the new product stuff, you know, we, you know, typically have a cautious approach to any new partnership until it really, you know, we begin to see the scaling of it. However, although, you know, AppFolio has the characteristics of being our largest partnership ever, in terms of, you know, the number of customers, but they have 19,000 customers, of which, you know, roughly 50%, we think, are right in our sweet spot of core, you know, customer profile. And we have lots of learnings from all the other partnerships that we've executed, that we're certainly applying to both M3 and the AppFolio partnership.
So, we feel really good about, you know, our, our playbook related to executing these partnerships, combined with the talent level that we've assembled to the position. So, you know, as Joel indicated, it'll certainly, you know, more noticeably begin impacting the second half of the year. But again, you know, we feel really good about the setup for, you know, 2025, 2026, and the impact of these partnerships long term.

This concludes our question and answer session. I would now like to turn the conference back over to Michael Praeger for any closing remarks.
Michael Praeger (CEO)
Thanks again, everybody, for your interest in AvidXchange. As the only publicly traded kind of company with really critical mass in the automation of accounts payable and payment automation, for the middle market, we believe we're in a really solid position to capitalize on the secular trend around digital transformation, of the back office. And given our disciplined execution in the face of, continued kind of macro challenges, along with our financial strength, we believe there's a significant runway for revenue growth, profitability, and value creation for investors. With that, we look forward to sharing our progress with you in our next earnings call. Thanks again, everybody.
