Thanks, Lori, and welcome to everyone joining us for AppFolio's fourth quarter and fiscal year 2023 financial results. I am pleased to announce a successful fourth quarter that caps off a year in which AppFolio increased the pace of innovation while prioritizing profitable growth.
Fourth quarter revenue grew 39% year-over-year to $172 million, contributing to an annual 31% increase to $620 million. Units grew 13% for the year to $8.2 million, our customer count expanded, ARPU increased, and payments continued to grow.
At the same time, we improved our margins driving non-GAAP operating margin to 24% during the fourth quarter, and non-GAAP free cash flow margin to 20%. AppFolio's strategy is all about delivering exceptional value for our customers, employees and shareholders. Our strategy has five components and starts with our commitment to differentiate to win.
There is no better example of how rapidly we are differentiating ourselves in AppFolio Realm. It unites all of our AI innovation under a common umbrella and touches every single one of our customers' workflows from leasing to maintenance and accounting.
Some of these AI features and services are included in the core product, while others are sold separately or included in our premium product tiers. 93% of our customers now use one or more AI-enabled features or services through AppFolio Realm.
That's twice the adoption of just one year ago, demonstrating the value our customers are realizing from Realm. We announced AppFolio Realm-X, the industry's first-ever generative AI conversational interface at NAA last year and we're piloting it with customers right now.
Through Realm-X, customers will be able to interact with AppFolio in plain language. It has three components. First, customers can ask Realm-X to explain how something works. They can ask for information, and they can ask for reports. Second, customers can also tell Realm-X to complete a task on their behalf like drafting a communication.
The third component is that customers can teach Realm-X to automate processes and workflows. This is crucial because our customers continue to tell us, their number one challenge is operational efficiency. They have talent and resource constraints and yet, they're still doing manual, repetitive tasks.
In the past, we designed products to help customers do the work. What we're building today will do the work for them. That's what differentiating to win means. The second component of our strategy is to unlock upmarket customers.
We are winning larger customers by expanding our coverage of property types, which we accomplished in 2023 through the launch of affordable housing. And by extending the value of our platform to scale with our customers' complex operations, whether built natively or delivered by our integration partners via AppFolio Stack.
As of the end of 2023, we've grown the number of units connected to AppFolio Stack partners to 1.5 million. Thanks to initiatives like these, more and more large residential portfolios made the switch to AppFolio in 2023. One of those customers was AMC, which maintains and operates over 11,000 multi-family units in Southern California.
Since going live late last year on AppFolio Property Manager PLUS, they're leveraging not just our core system functionality, but also AI Leasing Assistant, Lisa, Smart Maintenance, Websites, BillPay, and so much more.
AMC's President, Danielle McCarthy, had this to say and I quote, we see great potential in AppFolio's current offerings as well as in their constant commitment to innovation and view this partnership as a real investment in our future, end quote. In the fourth quarter, we introduced a third tier in our product line-up at NMHC's OPTECH Conference.
AppFolio Property Manager Max is designed for large operators with complex and diversified property portfolios. This new plan provides everything in PLUS as well as Leasing CRM that puts all lead data in one place for actionable insights.
Leasing Signals that enable property managers to make thoughtful pricing decisions using their own unique pricing strategy and public data. Custom Fields that allow property managers to capture, track, and report on any information with user-defined fields.
A Database API that gives property managers full access to their AppFolio database to build analytics, integrations, and data processes, and Max comes with dedicated customer success management. Max has been well-received and adopted by new customers as well as existing ones.
Through our product tiers, we create upgrade paths, so as our customers grow, we have offerings that grow with them. The third component of our strategy is to elevate the customer by driving their adoption and success on our platform.
Next month, we'll publish the second edition of our Annual Research benchmarking more than 5,000 property management employees. The report will show that maintaining high occupancy rates has become top of mind as rental markets become more competitive. And with operational efficiency continuing to be a challenge, reducing costs is key.
Property managers tell us they are finding savings by leveraging data to fill vacant units faster, centralizing their teams and resources, and adopting AI. These are areas where AppFolio will continue to innovate in order to deliver an exceptional customer experience.
We also heard that despite broader economic challenges, there is reason for optimism. According to the report, 66% of property managers expect their portfolios to grow in 2024 compared to 52% last year.
Last quarter, we talked about our new Bulk Actions functionality available to users of AppFolio Property Manager PLUS and Max, that supports customer needs of around managing move-ins and move-outs at scale.
It's valuable to our upmarket customers, particularly those with student housing in their portfolio given the seasonal patterns of the residential lifecycle. This past quarter, we expanded this functionality to Bulk Lease Renewals.
We recently heard from one customer, Gozen Hartman, CEO of Champagne, Illinois-based Fairlawn Real Estate, which manages more than 5,000 units on AppFolio Property Manager PLUS, that our Bulk Lease Renewal tool has reduced the time her team spends sending out lease renewals by 75%.
According to Gozen and I quote, it turns something that was looming and difficult into being easier and that ultimately enabled most of our team to continue leasing apartments and providing great customer service, end quote. That's the kind of improvement that makes a difference to people every day. That's how we elevate our customers.
The fourth component of our strategy is to scale the business. Our pursuit of profitable growth is in service of our customers. Because to be the innovative long-term partner they can rely on to power their businesses, we must be a healthy resilient business ourselves. In 2023, we made a commitment to operational efficiency.
We sharpened our focus on the closest to home initiatives that drive efficient growth and deliver extraordinary customer value. We right-sized our team and real estate footprint and we drove meaningful improvement in our infrastructure spend.
Ongoing discipline and our execution will allow us to reinvest in our platform, reach new customers and drive efficient growth. At the same time, we will continue to add and enhance our capabilities to grow ARPU, particularly in the upmarket segment. The final component of our strategy is great people and culture.
I'm inspired by our team's ability to rise to every challenge and deliver customer innovation and value at an exceptional pace. Earlier this month, we presented AppFolio's strategic priorities to our employees at AppFolio Kickoff 2024.
During the event, we had a chance to meet several customers who are using AppFolio in meaningful ways, hearing how our innovations are sparking productivity and helping communities thrive are powerful reminders of the impact we're making.
One of those customers, Neil Cadman, President of El Segundo, California-based Cadman Group managing 1,100 units on AppFolio Property Manager PLUS had this to say and I quote, I'm way past understanding a lot of the Xs and Os of AppFolio.
I just know when I turn on my computer, when I look at my phone, tenants can pay rent, we can lease units, it all works. We view AppFolio as Cadman Group and Cadman Group as AppFolio. It's why we keep coming back, end quote. Everything our team does is in service of customers like Neil and our great people and culture are creating these experiences.
I am grateful to every one of our customers, proud of our accomplishments and deeply believe in the direction of our Company.
Through our relentless focus on our customers, our disciplined investments, our passion to deliver industry-leading innovation, and our great people and culture, we are truly building the platform where the real estate industry comes to do business.
I'll now turn the call over to Fay Sien for more details on AppFolio's fourth quarter financial results..
Thank you, Shane. The fourth quarter marked an excellent end to a successful year, where we achieved strong revenue growth and accelerated profitability, while 2023 results laid the foundation for financial flexibility to help us achieve our goals in 2024.
In the fourth quarter, we delivered revenue of $172 million, growing 39% year-over-year and we generated free cash flow of 19.9% of revenue compared to 1% in the same period of last year.
Core solutions revenue was $41 million in the fourth quarter, a 17% year-over-year increase driven by new customers, additional units on platform, and continued adoption of AppFolio Property Manager PLUS.
At the end of the year, we managed approximately 8.2 million units from 19,737 customers compared to 7.3 million units from 18,441 customers a year earlier. This represents a 7% increase in customers and a 13% increase in ending units.
Growth in units was primarily driven by the timing of units added by new customers and existing customers expanded their portfolios at a higher rate than prior quarters during 2023. For the full year, core solutions revenue grew 18% year-over-year.
Fourth quarter value-added services revenue grew 48% year-over-year to $128 million, resulting in full year revenue growth of 39%. Annual growth was fueled by unit growth, continued strengthening in card adoption for rent payments, and our decision to stop waiving the eCheck fee. Card adoption for rent payments continues to exceed our expectations.
Turning to spending. We exited the quarter with 1504 employees, which is a decline of 16% compared to the fourth quarter of 2022, as the result of our efforts to align structure to strategy. Non-GAAP cost of revenue exclusive of depreciation and amortization was 35% of total revenue compared to 40% in the fourth quarter of last year.
The full year was 37% compared to 40% in the prior year. The gross margin increase was primarily due to our decision to stop waiving the eCheck fee and operational improvements.
As a percent of revenue, combined sales and marketing, R&D, and G&A fell to 37% in the fourth quarter of 2023 from 58% in the fourth quarter of 2022 due to growth in revenue and our collective focus on operational efficiency. For the full year, operating expenses as a percentage of revenue declined to 46% from 55% in 2022.
Sales and marketing expenses as a percentage of revenue decreased from 21% in Q4 2022 to 12% this quarter. For the full year, sales and marketing decreased from 21% to 16%.
By optimizing operations and maintaining discipline in our investments, we improved R&D expenses as a percentage of revenue from 21% in the fourth quarter of the prior year to 17% this quarter. For the full year, R&D increased from 20% to 21%.
Our G&A expenses as a percentage of revenue decreased from 15% in the fourth quarter of the prior year to 8% this quarter. For the full year, G&A decreased from 14% to 10%, reflecting our sustained focus on streamlining operations for greater efficiency.
Overall, our non-GAAP operating margin in the fourth quarter of this year grew to 24.3% compared to a loss of 2.7% in the same quarter of last year. Through disciplined execution of our planned strategies, we delivered a non-GAAP operating margin of 12.2% for the full year, which was a significant improvement from the operating loss of 0.6% in 2022.
Free cash flow margin this quarter was 19.9% compared to 1% in the same quarter last year. Full year free cash flow margin was 11.9% compared to a loss of 0.9% in 2022.
In 2024, we expect growth in card usage for rent payments to normalize and total payments revenue to moderate in the second half of the year with the anniversary of our decision to stop waiving eCheck fees.
Additionally, beginning in the second quarter, we plan to reduce certain transaction fees associated with card-based rent payments, which will further impact revenue growth. For all other value-added services, we expect seasonality to remain consistent with historical trends.
Our 2024 guidance for annual revenue is $755 million to $765 million, which implies a full year growth rate of 23% based on the mid-point of this range. We expect full year cost of revenue as a percentage of revenue to be slightly lower than 2023 as we continue to drive additional efficiencies.
Our 2024 ending headcount is projected to grow as we continue to invest in high-priority initiatives that enable us to achieve our strategic objectives. However, we expect the rate of headcount growth to be less than revenue growth as we maintain our focus on operational excellence.
In 2024, we expect to deliver non-GAAP operating margin between 21% and 23% of revenue, while generating free cash flow of between 17% and 19% of revenue. Diluted weighted-average shares outstanding are expected to be approximately 37 million shares for the full year.
Our fourth quarter and full year results demonstrates our continued commitment to being a healthier, more focused business, fueling our ability to serve customers and power the future of the real estate industry. Thank you all for joining us today. We look forward to seeing you soon. Operator, this concludes today's call..
