Earnings Call Analysis
Q4-2023 Analysis
Paymentus Holdings Inc
The company reported impressive fourth quarter results with revenue at $164.8 million, a 24.7% increase year-over-year, supported by robust transaction growth which outpaced revenue growth mainly due to an advantageous mix of billers. The contribution profit followed suit with a 22.7% increase to $66.3 million, driven primarily by higher transaction volume from both current and newly onboarded billers, underscoring strong business momentum and strategic growth initiatives. Notably, the contribution margin remained steady around 40.3%, indicative of efficient scaling despite the introduction of several large billers.
The quarter's success was fueled by higher-than-expected transaction growth spurred by billers launched earlier in the year, seasonal billers, and favorable renegotiated pricing on renewed contracts. However, the management highlighted that various external factors such as changes in payment amounts, biller mix, and fees could significantly influence contribution profit on a per-transaction basis, adding a layer of complexity to predicting future profit trends.
Adjusted gross profit increased 21.5% to $54.2 million, slightly trailing contribution profit growth, with increased employee-related expenses reported as a one-time event. The marginal 1.1% rise in non-GAAP operating expenses to $36.7 million reflects a strategic increase in sales and marketing as well as R&D efforts, while the record 95.4% surge in adjusted EBITDA to $19.9 million illustrates robust operating leverage within the business, even as the company managed to hire less than anticipated.
The stellar performance of the company is exhibited by its surpassing of the Rule of 40 for both the fourth quarter and full year, signaling its strong growth and profitability with values around 53% and 44%, respectively.
The company ended the fourth quarter with strengthened liquidity, showcasing a cash and cash equivalents balance of $183.2 million, up from $166.9 million, and a generated free cash flow of $16 million. Additionally, the healthy liquidity position is complemented by an increase in working capital and an uptick in shares outstanding, linked to both improved stock performance and the exercise of employee stock options.
Looking into the first quarter of 2024, revenue is expected to range between $170 million to $176 million, contribution profit between $64 million to $66 million, and adjusted EBITDA between $15 million to $17 million. The guidance for the full year 2024 predicts revenue between $720 million to $744 million, a 19.1% to 21.1% growth, with contribution profit ranging from $274 million to $288 million, up 16.6% to 19.5%. Adjusted EBITDA is projected between $65 million to $75 million, marking up to a 29.1% increase. These strong forecasts demonstrate continued growth momentum and are cautiously optimistic, acknowledging external factors that may impact contribution profit.

Good day, and welcome to the Fourth Quarter and Full Year 2023 Paymentus Earnings Conference Call. This call is being recorded. [Operator Instructions]
At this time, I will now turn the call over to David Hanover, Investor Relations. Please go ahead.
Thank you. Good afternoon and welcome to Paymentus Fourth Quarter and Full Year 2023 Earnings Call. Joining me today on the call is Dushyant Sharma, our Founder and CEO and Sanjay Kalra, our CFO. Following our prepared remarks, we'll take questions.

With that, I'd like to turn the call over to Dushyant Sharma, our Founder and CEO. Dushyant?
Thank you, David. We had a great quarter and a great year and we are looking forward to carrying our momentum into 2024. Even more exciting to me is my view that our 2023 financial performance reflects only a subset of the opportunities arising out of the innovation framework we have built over the years. Therefore, we are excited about our long-term future and believe we are just getting started.
Now, I'll cover our fourth quarter and the full year 2023 highlights. In the fourth quarter of 2023, Paymentus again delivered results that were well ahead of our initial expectations. Fourth quarter revenue was $164.8 million, up 24.7% year-over-year. Adjusted EBITDA, which as many of you know, is a significant financial metric for us, was $19.9 million for the quarter, up 95.4% year-over-year.
Fourth quarter contribution profit was $66.3 million, up 22.7% year-over-year. In addition to these results, we also exited 2023 with a strong bookings and a strong backlog that we believe puts us in a position to achieve the top end of our guidance without signing any new clients, but of course, timely completing our expected 2024 implementations. As you may recall, we shared the same sentiment last year around this time. For the full year 2023, revenue increased 23.6% over the last year to $614.5 million, beating our long-term target of 20% top line growth.
Adjusted EBITDA increased 103.1% to $58.1 million, far ahead of our long-term target of 20% to 30% and contribution profit was $240.9 million, growing 19.7%. In Q4, we added $12.2 million in contribution profit over the same period last year, while dropping $9.7 million of that to adjusted EBITDA. So, for the past few quarters, we have continued to demonstrate an ability to drop the majority of the incremental contribution profit dollars to the bottom line. We believe this highlights one of the key strengths of our operating strategy, our proven ability to expand our operating leverage without sacrificing growth or innovation. As we have shared before, at Paymentus, our goal remains to continue delivering high-quality earnings alongside solid top line growth. We are proud of what we have achieved to date and we expect to continue delivering long-term growth in both of these areas in the years to come.
Now, I'll review some of our key fourth-quarter business highlights and accomplishments. As I mentioned earlier, we finished 2023 with a strong backlog and are very pleased with our year-over-year growth. Of course, all of this continues to be driven by the strength of our technology platform and our IPN ecosystem, which enables our clients to participate in a broad and diverse network by merely integrating onto our platform.
Turning specifically to new client activity. During the fourth quarter, we signed several notable and large clients. We signed multiple large insurance companies, large utilities and large government agencies. We also signed a large property management company in the real estate sector and a large business in the retail sector. In addition, we signed several clients across various other verticals. We believe this broad mix of customer signings demonstrates the diversity of the businesses and verticals our platform can support. And as always, one of our key focus areas, continues to be onboarding our strong backlog in order to drive further growth. We are making incremental targeted investments in this area and believe these investments as well as the continually improving post-pandemic conditions that allows for a more in-person collaborative process continues to be a tailwind for us in this regard. As part of this effort, we have continued to ramp up hirings. We have made significant progress onboarding new clients since the start of 2023, including the launch of several large clients during the fourth quarter across various verticals, including multiple utilities, insurance companies, commercial entities, property management companies, government agencies, and financial institutions. Of course, we expect to make further progress throughout 2024, consistent with our growth plans and internal targets.
As we reflect on our platform and the ecosystem, we believe we are increasingly becoming a central hub to the entire bill payment ecosystem. When I step back and reflect on our product capabilities and who we currently serve with product offerings, it drives a strong personal belief that we are setting a foundation to become a large global fintech provider. First, we serve businesses of various sizes and industry verticals, engaging with their consumer and business customers and getting their bills paid through our platform. Second, we have banks and credit unions of various sizes sending payments from their customers to the billers using our platform and our ever-expanding IPN ecosystem. Third, we have millions of consumers and small businesses interacting on our platform and the ecosystem. And finally, we have clients who are disbursing and paying out millions of dollars using our payout and disbursement platforms. These billers, businesses, banks, credit unions and SMBs, all engage our direct product offerings that uniquely address their specific business and payment workflows. So, if you're an investor like me in this business, I hope you're as excited as I am about where the business is headed with ever-expanding TAM, along with our growth and profitability. In other words, I believe this is a long-term sustainable growth business with innovative platform and the company DNA.
In closing, we are proud to report another period of results that were ahead of our original expectations, both for the fourth quarter and the full year 2023. At the same time, we continue to prove our ability to increase operating leverage without sacrificing revenue growth. We ended the year with a strong backlog and solid sales momentum going into 2024 and of course, we intend to remain focused and disciplined in onboarding our strong backlog, which we expect to fuel our future growth.
Now, let me turn it over to Sanjay to review our financial results in greater detail. Sanjay?
Thanks, Dushyant, and thank you all for joining us today. Before I discuss our quarterly and full-year results and our 2024 outlook, I'd like to remind everyone that the financial results I'd be referring to include non-GAAP financial measures. As David mentioned earlier, our Q4 press release and earnings presentation include reconciliations of the non-GAAP financial measures discussed on this call to their corresponding GAAP measures. Both of these are available on our website.
Turning to Slide 5. For the fourth quarter of 2023, we delivered another quarter of very strong financial results. We believe these results continue to demonstrate the resiliency, stability, and strength of our business. Our fourth quarter results included revenue of $164.8 million, contribution profit of $66.3 million, and adjusted EBITDA of $19.9 million.
Our results came in higher than we originally expected and I'll discuss the drivers of our outperformance in more detail shortly. We also continued to experience solid business momentum in the fourth quarter. This enabled us to once again exit the quarter with a strong backlog while further increasing our cash position.
Now, let's review our fourth quarter financials in more detail. Fourth quarter 2023 revenue was $164.8 million, up 24.7% year-over-year. This growth was largely driven by increased transactions from existing billers, the launch of new billers, and increased activity in our instant payment network or IPN business. The number of transactions we processed grew to 124.8 million in the fourth quarter, up 28.4% year-over-year. Our transaction growth exceeded revenue growth during the quarter, primarily due to biller mix.
Fourth quarter 2023 contribution profit increased to $66.3 million, up 22.7% year-over-year. This year-over-year increase in contribution profit reflects higher transactions from existing billers and the launch of new billers. Contribution margin was 40.3% for the fourth quarter, essentially flat compared to 40.9% in the prior-year period, despite adding a number of large-sized billers to the mix throughout the past year.
Contribution profit in the fourth quarter surpassed our expectations and was actually our best quarter in 2023 in terms of year-over-year growth. This outperformance was primarily driven by 3 key factors. First, we saw higher transaction growth than we had expected initially during the quarter. The growth was driven by increased transactions from newer billers that were launched earlier in the year with the incremental transactions driven by seasonality and adoption success. Second, we saw growth from billers who were seasonally strong in the fourth quarter. And third, we realized the benefit of improved pricing from some billers upon renewal of their contracts. Contribution profit per transaction for the quarter was $0.53, which was modestly down from $0.56 in the prior-year period, primarily due to biller mix.
As we stated in the past, variables outside of our control, such as an increase in the average payment amount, changes in the payment mix, biller mix, CPI, and card network fees, et cetera, can significantly influence and diminish the utility of contribution profit on a quarterly and per transaction basis.
Fourth quarter 2023 adjusted gross profit was $54.2 million, up 21.5% year-over-year. Year-over-year adjusted gross profit growth marginally trailed contribution profit growth, primarily due to increased employee costs we recorded during the quarter related to customer support that are non-recurring. Fourth quarter 2023 non-GAAP operating expenses increased to $36.7 million, marginally up 1.1% year-over-year. The increase was primarily due to increased sales and marketing expenses and research and development expenses, net of savings we realized in general and administrative costs. We expect to increase sales and marketing expenses as we continue to focus resources on the execution of our go-to-market strategy and increase in investments related to converting our strong pipeline to bookings and onboarding our strong backlog.
Additionally, we started to see increased hiring in the fourth quarter, including some hirings that we had originally planned for the third quarter of 2023. Fourth quarter 2023 non-GAAP net income was $13.9 million or $0.11 per share, compared to non-GAAP net income of $5.1 million or $0.04 per share in the prior-year period.
Fourth quarter 2023 adjusted EBITDA was $19.9 million, a record 30% of contribution profit, up 95.4% compared to $10.2 million or 18.9% of contribution profit in the prior year. This very strong quarterly performance compared to the guidance we previously provided was primarily driven by 2 key factors. First, we benefited from increased contribution profit due to transactions growth and the reasons highlighted earlier. And second, hirings were less than we had expected in the quarter, resulting in lower operating expenses. Even taking into account these unexpected variables which benefited us, we believe our strong adjusted EBITDA margin demonstrates the inherent operating leverage we have in the business and our ability to adapt to changing market conditions as we continue to grow.
Related to this, we also exceeded the Rule of 40 for the fourth quarter, coming in at approximately 53%. This is a measure we take very seriously, and our team here monitors it very closely. This is our third consecutive quarter exceeding the Rule of 40.
Turning to Slide 6. I will summarize our full-year 2023 financial results, which also came in higher than we originally expected. Revenue for the full year increased 23.6% to $614.5 million, driven by 24.9% increase in transactions from new billers, as well as transactions growth from existing billers. Contribution profit increased 19.7% to $240.9 million, primarily due to increased transactions and repricing initiatives. Lastly, adjusted gross profit increased 23.1% to $199.2 million. Non-GAAP operating expenses increased to $150 million, up 6.8% year-over-year, primarily due to higher sales and marketing expenses as we continue to focus resources on the execution of our go-to-market strategy.
Non-GAAP net income was $40.1 million or $0.32 per share, compared to non-GAAP net income of $14.8 million or $0.12 per share in the prior-year period. Adjusted EBITDA increased 103.1% to $58.1 million, primarily due to increased adjusted gross profit net of increased non-GAAP operating expenses. We exceeded the Rule of 40 for the full year ending at approximately 44%. We are proud to report that $29.5 million of $39.7 million contribution profit increase, representing 74% incremental contribution profit in the fiscal year '23 flowed through to adjusted EBITDA.
Now I'll discuss our balance sheet and liquidity position on Slide 7. We ended fourth quarter with cash and cash equivalents of $183.2 million compared to $166.9 million at the end of Q3 '23. The $16.3 million increase was primarily comprised of $24.4 million of cash generated from operations, offset by $8.4 million used in investing activities, primarily internal use capitalized software used to drive growth and innovation. The company does not currently have any debt. Our free cash flow generated during the quarter was $16 million. Our days sales outstanding at the end of fourth quarter was 43 days compared to 45 days at Q3 '23, within our expected range. Working capital at the end of the fourth quarter was approximately $208 million, an increase of approximately 6% from the end of Q3 '23. We had 126.5 million diluted shares outstanding as of December 31, 2023, compared to 125.6 million diluted shares outstanding at the end of Q3 2023. The increase was largely due to improved average stock price during the quarter and, to some extent, due to the vesting of employee-restricted stock units and exercise of stock options.
Now I'll turn to our Q1 '24 and full year 2024 guidance for revenue, non-GAAP contribution profit, and adjusted EBITDA on Slide 8. Taking into account our progress to date for Q1 '24, our guidance is revenue in the range of $170 million to $176 million, contribution profit in the range of $64 million to $66 million, and adjusted EBITDA in the range of $15 million to $17 million. Before discussing full-year guidance, I want to mention that we are continuing to follow the same prudent approach to guidance that we followed during 2023 as uncertainty around the macroeconomic environment still exists.
For the full year 2024, we currently expect revenue in the range of $720 million to $744 million, reflecting growth of 19.1% at midpoint and 21.1% at high end. Contribution profit in the range of $274 million to $288 million, up 16.6% at midpoint and 19.5% at the high end. Our growth range for contribution profit is wider than revenue primarily because, as we have said before, contribution profit is subject to a number of external factors that are beyond our control. Accordingly, we are taking a cautious approach on this metric.
And finally, adjusted EBITDA in the range of $65 million to $75 million for the year, representing 20.5% increase at the midpoint and 29.1% at the high end. Please note, this adjusted EBITDA guidance reflects the annual merit awards for our employees and our expectation that the increased hiring pace we saw in the fourth quarter will continue to pick up in 2024. It also takes into consideration the slower operating expense growth we saw in 2023, which was largely a reflection of the accelerated operating expense growth we had seen in the prior 2 fiscal years, primarily as a part of going public. Now that this period has passed, we expect to deliver a more normalized operating expense growth rate in 2024.
During our last earnings call, we provided long-term growth targets for both revenue and adjusted EBITDA or our 2 primary financial metrics. We stated our goal to grow revenue at approximately 20% annually and to grow adjusted EBITDA dollars between 20% to 30% annually. The guidance that we have provided today for the full year 2024 reflects these long-term targets. Regarding contribution profit and operating expenses, which we consider secondary financial metrics, we plan to actively manage our operating expenses, dialing them up or down as necessary depending on how contribution profit is trending throughout the year to enable us to remain a Rule of 40 company on an annual basis. We managed this quite well in 2023, and we believe we can do so again in 2024, given our strong operating leverage.
In summary, we reported exceptional fourth quarter and full year 2023 results. Throughout 2023, we consistently demonstrated our ability to generate strong revenue, contribution profit, adjusted EBITDA, cash and bookings growth. This enabled us to end the year with a substantial backlog. Based on this solid footing and strong visibility, we continue to believe we are well positioned for 2024.
Thank you, everyone, for your attention today. And now I'll turn it back to Dushyant for final remarks before we open up the call for questions.
Thanks, Sanjay. I'm proud that our team came together and significantly beat our original expectations for 2023, which we had set out around the same time last year. I believe this performance illustrates the resilience of our business despite the difficult macro environment we dealt with. Sanjay just covered our guidance for the full year and the first quarter 2024. As I shared earlier, we feel good about the guidance based on the strength of our backlog. On that note, also want to thank all of my team members for their continued efforts and dedication.
That concludes our prepared remarks. I'll now open the line up for questions.
[Operator Instructions] The first question is from the line of John Davis with Raymond James.
This is Madison on for JD. I wanted to start on the revenue guide. Obviously, it calls for roughly 19% growth here. Doesn't include any new client wins and understand the conservatism. But can you help us understand just how much new clients have contributed to growth in the past? I'm just trying to get a sense for the potential upside of new client growth goes as kind of planned given the strong backlog and sales trends you're seeing.
Madison, appreciate the question. The growth of the new clients and the growth of the existing clients, these are the 2 contributors for our growth generally year-over-year. And I would say we generally do not disclose the breakup of the 2. I would say that the growth this year, we are seeing the 19.1% at midpoint, that's comprised of both these factors, as I mentioned. And I would say they are in a very similar ratio what you saw last year. They are in a pretty close range of those numbers last year as well.
The trends are continuing as we expected. And I think as we are guiding the high end at 21.1% and as Dushyant just mentioned, if all our client implementations happen on time as planned, I think that should get us to high end. But I would say no new customers are planned in this year, which we will have to win this year and implement this year. All of our revenue is -- expectation is based on the client winnings we had till the end of 2023.
Got you. Yes. That's helpful. And it's probably worth noting that, obviously, you outperformed that initial revenue guide from last year by mid-single-digit percentage wise. And then just as my follow-up here on capital allocation. Obviously, you talked about the pristine balance sheet, strong cash position, no debt, generating nice free cash flow now. Can you just talk about your capital allocation philosophy and then just any color you could possibly give on how you guys are thinking about cash flow in '24 would be helpful.
Sure. Madison, we are very glad to be in a great position in the current economy to have a very good balance sheet. $183 million on the balance sheet gives us a lot of comfort and opens a lot of avenues for us to think about. But our priorities for capital allocation or cash spending remain unchanged since what we have discussed in the past. We want to grow organically. And the biggest opportunity for us to spend cash to prove the best results for us is to invest in hiring the sales and marketing team so we can build a better pipeline for growth for outer years.
In fact, I would rather highlight the current year's expectations for growth of revenue do not need any additional sales team or additional sales bookings. But we plan to invest in our sales team, which is -- which we think is the right measure for us to spend money.
Other than this, we currently do not have any other plans to spend cash and I think we are headed in the right direction. Starting from Q4 itself, we saw that trend happening, and we are excited to make that happen more in this year and build a great pipeline.
The next question is from the line of Dave Koning with Baird.
Yes. A nice job. And I guess my first question, you gave -- at the end of '22 you gave, I think, a little over 1,900 clients. So last year, [ we could ] kind of back into like 10% client growth and mid-teens revenue per client growth. Did you give that number at the end of '23? I don't think I saw it in the presentation, but maybe if you could just give us a little bit of how much clients grew and then how much revenue per client grew.
Yes, David, the new number -- that's an annual number we disclosed, and our 10-K will be filed shortly. And the number will be in there and it's 2,200. So it's a 300 increase from the last number you saw. And the increase prior to that was 200. So definitely, we are marching at an accelerated pace than we were marching earlier. And I think revenue per client is, I would say, is getting better.
Interesting the revenue per client, I would also highlight, David, is not really kind of the most optimum metric to look at. Given the kind or given the size of the clients we are getting into, we are getting large enterprise customers as well as small and medium-sized billers from various verticals. Our mix is kind of becoming different than it was a few years ago. So I think looking at revenue per client may not be right metric, but I get it that that's an easy metric to look at and see the trends. I would say just the growth of billers itself is more relevant than revenue per biller.
Yes. Got you. No, that's -- that's helpful. And I guess just a follow-up question. You've become quite profitable so quickly in the last few years. And now we can look at -- like we can look at earnings as a valuation metric. And I'm just wondering, do you have like a normalized tax rate or something that we should use when we start thinking about how to think about earnings?
Yes, David, that's a great comment. Thank you for that. We are profitable, and we definitely want to be and we think we'll be profitable going forward as well, given the strong operating leverage this business has. In terms of tax rate, we are profitable, and we kind of exhausted all NOLs this year, a very small portion is left, which will be used next year. So going forward, for the long-term planning for earnings, I would suggest you use the rate which is closer to the statutory tax rate in the U.S. counting states, I think you should use approximately 25% tax rate.
Yes, that makes sense.
The next question is from the line of Will Nance with Goldman Sachs.
Dushyant, you called out a number of client wins in the quarter across a number of verticals. And maybe wondering if you could kind of double click on like the mix of incoming clients. Are there any verticals where you guys are seeing particularly increased traction or where you're getting increasingly optimistic that maybe could unlock some additional growth, maybe verticals you haven't played in historically as much?
Yes, actually a great point. Well, from our perspective, during the IPO road show, we actually had a comment that wherever there is a bill, there is a payment, and wherever there is a payment there is Paymentus. And I think that's coming to pass at this point where from all of our channels, whether it's direct acquisition of clients or through channel partners of various kinds, what we are observing is that the needs of the customers is the same, that they want to automate their complex payment and business workflows and our platform fits the bill perfectly for that.
So as a result, we are growing in all different verticals. Utilities remains a strong vertical for us, but many other verticals, as I named, we are seeing traction in. So we're very excited about the future actually. And one of the other things which is interesting is, as we are entering into some other verticals, we are noting that it's not just the payments in, even payment out, so disbursements and payouts becomes an important transaction flow that we could acquire or automate through our platform. So we're excited about that as well.
Yes. Appreciate all that. And then just maybe on some of the IPN comments, you kind of mentioned the progress and seeing more integration with bank bill pay. Maybe you could just talk about the opportunity there long term. I think a lot of people would consider Paymentus and companies like that kind of be in opposition to traditional bill pay centers at the banks. So how do you see that kind of playing out over time? Are there opportunities to maybe work more closely with some of the incumbents in the space? And how do you kind of see the IPN strategy playing out specifically to kind of the bank bill pay market?
Thank you, Will. I think this is an interesting scenario. I think what we felt right from the beginning of the business that each billing company, if I can liken it to the analogy of cellphone network, each billing company is like a cellphone tower. And if you have enough of the billing companies like we do and we continue to -- and we have built the platform and the ecosystem where we are signing increasingly at a faster pace, the billing companies of all sizes and various verticals onto the network, the cellphone network, if you will, or the biller network, becomes increasingly valuable on its own in addition to the revenue we generate from the billers themselves. So what that means is that any bank who has any desire to attract customers or not -- or stop losing the customers or the payment volume they've historically lost to Paymentus, if they want to participate and continue to maintain their customer base, they have to use a real-time network like IPN. And since we are the leader in the space, or at least we believe we are the leader in the space, we believe that this is -- as we bring more and more billers, this becomes even more valuable for banks and other third-party providers who want to provide aggregated consumer bill payment.
So, in some ways the chasm that existed between the consolidated business bill payments to the biller direct bill payments is being sort of evaporated or being reduced or eliminated through instant payment network. So we're very excited about the future here. And frankly, as the time progresses, it will start to become more and more evident how and why we are winning the type of customers we are winning.
Got it. Super interesting.
Thank you. The next question is from the line of Darrin Peller with Wolfe Research.
Nice job on this. Maybe just touch a little bit more on the landscape for a minute, because I think I heard you mention pricing a couple of times in your prepared remarks. Maybe if you can give us a little more understanding on how receptive clients have been to this and where Paymentus generally felt leveraged to do so. Maybe add on to it just overall competition. It looks like you guys obviously have differentiated yourselves as time goes on more and more. So maybe just any more color on if you've seen any incumbents do anything differently or perhaps new startups.
Sure. Great question, Darrin. I think from our perspective, the approach we took during the inflation -- inflationary period, or high inflationary period was we wanted to work with our clients. We wanted to demonstrate that we are a long-term partner and we understand the pain point that just because the inflation has come up rather quickly, it may dissipate quickly as well. So you wanted to give a little bit of a time for customers to understand that they are working with a great partner in addition to having a great platform like we support or we offer. And that approach actually worked extremely well.
So, we were able to walk the customers through the pain point we were suffering publicly. As you all know that we were being called out multiple times about the inflation impact we were facing. We were able to show that combined with the data, obviously, the detailed data customers were privy to, we were able to renew the pricing, update the pricing, customers were rather understanding. So, we feel good about where our contractual arrangements are with the client, where our pricing capabilities exist with the strength of the platform and the technology capabilities we support. So, should a situation like this were to arise in the future, it gives us confidence that our approach and methodology of taking a long-term view to customer service and then adjusting the pricing could work again well for us.
[ That's just cool ]. Maybe just one more on the operating leverage side. If you can give us a little bit more color on your operating expense plans and the cadence expected for '24. I think perhaps just a little more color on where you think you need to invest.
I would say that you saw that the growth this year was 6.8% full year, and next year, while we don't guide for OpEx as such, but you can, I think, model it out, looking at the guidance we are giving for the other 3 metrics. You will see that the OpEx is currently expected to grow in mid-teens. That's what you'll come, I would think, looking at what we provided.
Yes. Yes.
We are actually taking a prudent conservative approach in terms of what we need to do. And as I mentioned earlier, we don't really need to spend OpEx, majority of the OpEx is not needed to be spent for this year's growth. This year's growth is coming from bookings we did last year. We're planning to spend more in terms of what we need to book for outer years growth. So in terms of your main question, where will the spend be, majority of the spend will be in sales and marketing. I think R&D and G&A will marginally go up, but not significantly. The growth will -- OpEx growth mainly be in sales and marketing.
That said, I also want to highlight one thing. Majority of the spend is discretionary in nature. And we manage our business very carefully. In fact, there is a regular review of how the OpEx is trending and we can dial up and down based on how the CP is trending. So operating leverage is strong. As you saw last year, like we dropped 70% plus to the bottom line of incremental CP dollars. It can happen again, but we are not planning to do that by choice. So, I think we can manage it the way business is progressing, but we are glad to be in a position of operating leverage the way we are. The next question is from Andrew Bauch with Wells Fargo.
Just wanted to put a finer point on the hiring plans, particularly in sales and marketing that you highlighted. Sanjay, I know you mentioned in your prepared remarks that it was a function of converting the backlog, but then you also said just now that extending the growth in the out years is a priority. So, I guess, qualitatively, like how do you kind of anticipate these sales and marketing investments as they come on to augment your go-to-market strategy? And then if we can just put a finer point quantitatively, like what should we ultimately be kind of expecting based on your current plans for sales and marketing expense growth in '24?
Yes. Andrew, we -- as I said, from the modeling perspective, you would come at around 15%, I think, at the midpoint of growth of OpEx. And to put a finer point quantitatively, I would say, I can't give a percentage specifically here, but I would say a bigger piece is or material piece is for sales and marketing and the remaining piece for R&D and G&A. And a piece also depends on G&A in terms of how the few things come up, D&O insurance renewal, for example, a couple of renewals, we got a good benefit last year. And we don't know if the market trends of those costs, which are significant costs, where do they go this year, are they going to stay flat or go up? But I would think they will marginally go up, not significantly. So, take it that biggest piece of the increase in sales and marketing and remaining on these 2.
Now within sales and marketing, if I have to think about how much will go for growth of pipeline for outer years versus the backlog implementation, I would say in these 2 things as well, the material portion would go for generating additional pipeline for outer years and the smaller piece or a modest piece for backlog implementation.
And then the qualitative piece, like is there anything changing in the go-to-market strategy?
Well, our basic go-to-market strategy is not significantly changing. One thing which we are continually looking at, are there more verticals where we need to get into or can get into. We've made a significant progress, I would say, in the last 2 years in diversifying more into newer verticals, and we are seeing good progress there, and good traction there. So, our pace to accelerate, diverging into new verticals would continue. But other than that, there is no change in our strategy overall.
Got it. Makes sense. And then my follow-up was, Sanjay, you mentioned that the contribution guide was slightly wider than the revenue guide that you gave. You called out the uncertainty around macro and a lot of the mix dynamics. I mean, are you seeing anything thus far into 2024, be it around amount type biller, or the network fees, that would lead you to inform us all on that wider range for contribution profit?
So Andrew, that's a very interesting question. Interestingly, we are not aware of any specific change here. What we've learned among, I would say, in the last 2 quarters, when we look at all the contribution profits for all the quarters and try to analyze all the trends, what we've noted is that the degree of visibility at any given point in time for the current quarter is much better than the full year and that's where we are. We look at our Q1 guidance versus full year, we are taking a broader approach, just because the quarterly variability exists. For example, you'll see Q1 '24 growth exceeds the revenue growth. I mean, Q1 '24 CP growth exceeds revenue growth. And Q4 '23 was similar revenue growth, but it changes in other quarters. So, quarterly variability exists. And it's one of the most difficult metric to forecast.
But that said, the variability on CP does not impact our bottom line EBITDA, and we can calibrate the OpEx to manage our profitability, depending upon how the CP is trending. So, as a result, I would say that the utility of CP or contribution profit is a key -- as a key metric is diminishing over time. Hence we also call it a secondary metric, where the utility is limited, and we mainly use it to calculate Rule of 40. Hence, we thought it's prudent to take that approach rather than taking a narrow range as there are so many factors. And ultimately, we can manage through to our bottom line target by dialing up the OpEx up or down.
Maybe this was a mouthful, maybe this was more than you asked for, but hope it provides some perspective and insight into how we think about this metric.
No, it's helpful.
And also, if I may add, what Sanjay mentioned earlier was that to deliver 2024 growth, OpEx actually, even though everyone knows that we work in the nondiscretionary, we service the nondiscretionary industry, but our own internal OpEx in the context of 2024 is actually rather discretionary. So, we are able to turn the dial up and down, because of the operating leverage we have. So, we feel good about the top and the bottom end of the guidance, and despite the variability in the CP. And that's essentially the message you want to communicate. We know the trends in the business. We are feeling good about how we are capturing the market share and how we are able to profitably grow the business. All of that is moving in the right direction. Now, loud and clear.
The next question is from the line of Tien-Tsin Huang with JPMorgan.
Just a couple of clarifications. Just -- did you share the NRR for the year and how that came together and how fiscal '24 might be different? And also, did you disclose the bookings or backlog growth in '23 versus the prior year? Just curious on the magnitude of benefit there.
Tien-Tsin, no, we have not disclosed the numbers for the things you asked for.
Okay. Anything qualitative to share then just on the bookings or backlog front...
Qualitatively I can share...
Yes.
Yes, sorry. Yes, quantitatively, I would say our NRR as well as bookings and pipeline, they are growing -- they are going at a very decent pace, I would say. And that's giving us all the confidence to not only exceed our Q4 expectations, we delivered a strong quarter, we are very proud of that, and at the same time, Q1 also we are marching in a very good way. And I think we are headed for the, I would say, in the right direction for the whole year, given that we exited with a very strong backlog. So I think all these metrics qualitatively are providing us a lot of encouragement and confidence.
And Tien-Tsin, if I may add to that, was that one of the key reasons I wanted to point out the point that we exited 2023 with enough in the bag that we could actually deliver the top end of the guide for any -- all of the 3 matrices, the 2 primary and 1 secondary being CP. That's primarily based on the strength of the backlog and that is growing year-over-year. And we are feeling good about 2024 as well.
Yes. No, it sounds that way. That's why I thought I'd ask the question. Just my quick follow-up then on the drop-through or incremental margin around EBITDA was quite strong in '23. It's running around, what, 50% in fiscal '24, looking at my simple math. So just to make sure, it sounds like there is some hiring that will come through that you called out. I know you'll adjust OpEx depending on where contribution profit lands. But is that the primary difference in thinking about drop-through or incremental margin in '24 versus '23?
That's right.
The next question is from the line of Rebecca Lu with Citi.
Can you give us an update on the JPMorgan partnership? I think a year or 2 ago, we expected that partnership to have a pretty meaningful contribution in 2024. What do we think now?
Thank you, Rebecca, for the question. We are very proud with our -- very proud for our partnership with JPMorgan Chase. They're a great partner, a great organization. And it's going extremely well in all areas. And we are looking forward to a great 2024 with JPMorgan Chase. We also have a very strong partnership ecosystem, and we are looking forward to -- and frankly, as you can think about our go-to-market strategy, as Sanjay was also mentioning earlier, that increasingly partnerships become a big factor for us. So JPMorgan Chase is a strong partner for us, but also we have other partners, software vendors, fintech providers and so on.
Okay. And I want to ask about the contribution profit in a slightly different way. The profit margin has been -- it declined last year because we had some negative impacts from inflation. And if we're looking at the 2024 outlook, even at the top end of the range, we're also assuming a decline as well. Is it just conservatism or are there anything else that we might not be thinking about?
So, Rebecca, there are 2 pieces -- there are 2 answers to this. I'll share individually. Number 1, as we are onboarding larger customers, enterprise customers -- enterprise customers pricing definitely is different than smaller or mid-sized customers due to the volume discounts they get, because they've got bigger transactions -- or sorry, much larger transaction base. So I think as a result of that, our contribution profit margin is getting softer a little bit, but that's totally fine, given our strong operating leverage and hence we call contribution profit or contribution margin as our secondary matrices because they don't really matter as much to our long-term growth model, which are purely dependent on the revenue growth and EBITDA dollars growth.
So, it's a good question to analyze that how the CP margin is going. But at the end of the day, that can easily be managed by adjusting, dialing up or down over OpEx. So, it doesn't really matter to our bottom line. I think there could be situations, you will see that if CP percent is getting softer, our EBITDA could still get better because we can manage our expense better. And in our current long-term model, which we have talked about, i.e., 20% top line growth and 20% to 30% bottom line adjusted EBITDA dollars growth annually, I would think if CP margin gets better, which is also a probability, depending upon what kind of customers we get, I would think there's an upside to EBITDA. Although we are not planning to get there right now, I think we are applying a prudent approach. But what I'm just trying to say is contribution profit and contribution margin are really secondary. And over analysis of that might not produce an optimum result to understand the company.
And if I may also say one more thing, as Sanjay has alluded to, as your biller mix changes and the larger biller comes to play, imagine a scenario where we sign a large deal where we are going to have a contribution profit of, say, $1 million. That changes -- we are less concerned at that point exactly what each transaction is -- contribution profit for each transaction is. We are more concerned about how quickly and how efficiently can we serve that customer and what will be the net operating margin from that biller is once they're live on our platform, which ends up being very good based on the operating leverage we've been talking about.
There are no further questions in queue. I would like to turn the call back over to Dushyant Sharma for concluding remarks.
Well, thank you, everyone, for joining the call today. I really appreciate the time. Have a great day. Thank you.
That concludes today's conference call. Thank you for your participation. You may now disconnect your lines.
