Thanks, Matt.
Our revenue for the third quarter came in below our guidance range, predominantly driven by pressure on our transactional and lower margin services revenue streams. However, we also saw an acceleration in our higher-margin subscription revenue. Despite total revenue coming in below our guidance, our adjusted EBITDA results exceeded the high end of our guidance due to proactive cost management and a more favorable revenue mix. Additionally, our ARR, backlog and user growth continue to give us confidence in the continued acceleration of higher-margin subscription revenue.
I'll begin by reviewing our results for the quarter and conclude with updated guidance for the fourth quarter and full year of 2022. Total non-GAAP revenue for the third quarter was $144.9 million, an increase of 14% year-over-year and 3% sequentially. The year-over-year increase for the quarter was primarily driven by an increase in subscription revenue resulting from customer go-lives, specifically within our digital banking business, where we had more go-lives take place in the third quarter than during the entire first half of the year. Our sequential growth was the result of solid organic growth and the contribution of go-lives, which resulted in the highest number of users added in the quarter in 2 years.
Transactional revenue represented 11% of total revenue for the quarter, down from 14% in the prior year period and 13% in the previous quarter. The year-over-year and sequential decline in transactional revenue was largely driven by a decline in transactional volumes within our digital banking and Helix businesses. Usage-based revenue in our Helix business declined from prior quarters, and some of our customers observed elevated transactional volumes during the spring tax season. This, combined with the continued year-over-year contraction of our bill pay business is putting greater than expected downward pressure on transactional revenue.
Services and other revenue was 15% of total revenue for the quarter, down from 16% in the previous quarter. Services revenue is below expected levels due to a decline in customer spend on professional services and consulting, which was concentrated to some of our larger customers. These types of projects are generally more discretionary in nature.
Annualized recurring revenue or ARR grew to $633.7 million and 18% year-over-year and 3% sequential increase. The year-over-year growth was primarily from net new and cross-sell bookings within our digital banking and lending businesses. The sequential growth was also driven by the bookings success in the quarter, partially offset by the decline in usage-based transactional revenue. While ARR can have limitations as a key performance indicator, we believe it serves as a better barometer for net new and cross-sale bookings given that our backlog metric can be inordinately impacted by the seasonality of renewal activity.
We ended the quarter with approximately $1.4 billion in backlog, an 8% increase year-over-year and a sequential increase of approximately $22 million. The year-over-year and sequential increase in backlog was largely the result of net new and renewal bookings.
Gross margin for the third quarter was 52.1%, up from 51.9% in the third quarter of 2021 and 51.3% in the previous quarter. The year-over-year and sequential improvement in gross margin was attributable to an increased mix of higher-margin subscription revenue resulting from go-lives during the quarter. The sequential gross margin improvement was also the result of improved efficiency of resources delivering and supporting our solutions.
Total operating expenses for the third quarter were $69.8 million or 48.2% of revenue compared to $62.4 million or 49.1% of revenue in the third quarter of 2021 and $67.4 million or 48% of revenue in the second quarter of 2022. The year-over-year percent of revenue decrease was predominantly driven by improved R&D cost scaling in addition to a reduction in recruiting expenses and spending with third-party contractors. The slight sequential increase in operating expenses as a percent of revenue was driven by an increase in headcount concentrated within R&D and sales and marketing.
Adjusted EBITDA was $10.8 million, up from $7.3 million in the third quarter of 2021 and $9.7 million in the previous quarter. Our adjusted EBITDA overperformance relative to our third quarter guidance was attributable to a more favorable mix of higher gross margin revenue and effective cost scaling.
We ended the quarter with cash, cash equivalents and investments of $395.7 million, down slightly from $399.3 million at the end of the second quarter. Cash flow generated from operations for the third quarter was $6.1 million, which benefited from effective working capital management. We generated negative free cash flow in the quarter of $3.9 million.
Based on enhanced profitability projections and normal seasonality, we expect fourth quarter cash flow from operations and free cash flow to be positive. As Jonathan mentioned, we believe our cash position and projected future cash flow generation affords us the ability to evaluate capital deployment opportunities while continuing to ensure we're in a position to service our convertible debt balance, the vast majority of which does not come to maturity until late 2025 and 2026.
Let me wrap up by sharing our fourth quarter guidance and updated full year guidance. We forecast fourth quarter non-GAAP revenue in the range of $148.4 million to $150.4 million. We're updating our full year non-GAAP revenue guide to the range of $568 million to $570 million, representing year-over-year growth of 13% to 14%. This guidance incorporates our revised revenue expectations taking into account the impact we're seeing to discretionary services and transactional revenue.
We forecast fourth quarter adjusted EBITDA of $10.5 million to $12.5 million, and we're updating our full year 2022 adjusted EBITDA guidance to the range of $39 million to $41 million, representing approximately 7% of non-GAAP revenue for the year. Despite the revenue headwinds we're observing, we're still able to produce meaningful adjusted EBITDA driven by a more favorable revenue mix and proactive cost management.
Also incorporated into our guidance is the impact of Sensibill, which we acquired in October. We expect Sensibill to generate low single-digit millions in revenue and low single-digit millions in adjusted EBITDA loss for the full year of 2023, with an immaterial impact to Q4 of 2022.
As we continue to go through our 2023 planning process, I want to share our preliminary view on our expectations based on the trends we're seeing and the proactive measures we're taking. We continue to believe our subscription revenue will show an accelerated growth rate for the full year 2023 as a result of the bookings success we've observed year-to-date, our sales pipeline and the strength of leading indicators like ARR. However, we believe that subscription revenue growth will be partially offset by reduced expectations for our transactional and services revenue as well as our reduced expectations for Europe.
Based on what we're seeing in the second half of this year in transactional and services revenue, we anticipate our total revenue growth rate in 2023 will be relatively flat to the full year growth rate implied in our revised 2022 guidance. Despite this reduced total revenue outlook, we do expect an acceleration of subscription revenue growth and expanded adjusted EBITDA margins for the full year 2023.
With that, I'll turn it back over to Matt for closing comments.
