Brian Miller
Chief Financial Officer at Tyler Technologies
Thanks, Lynn. Yesterday, Tyler Technologies reported its results for the first quarter ended March 31, 2023. Total revenues for the quarter were $471.9 million, up 3.5%. Organic revenue growth, which also excludes COVID-related revenues was 7.2%. Last year's first quarter included $20.6 million of revenues from COVID-related initiatives, at our Digital Solutions division, formerly NIC, all of which ended in 2022.
License revenue declined 39% as our new software contract mix continued to shift to SaaS at an accelerated pace. Professional services revenue declined 13% due to completion of COVID initiatives, but rose 4.7% organically. Subscriptions revenue increased 14.3% and organically rose 16.4%. Within subscriptions, our SaaS revenues grew 24.4% to $126.6 million and transaction revenues grew 7.1% to $153.9 million. On an organic basis, which also excludes COVID-related revenues, Transaction revenues grew 13.1%.
We added 145 new SaaS arrangements and converted 73 existing on-premises clients to SaaS with a total new software contract value of approximately $86 million. In Q1 of last year, we added 149 new SaaS arrangements and had 88 on-premises conversions, with the total new software contract value of approximately $76 million. Our new SaaS bookings in the first quarter added $17.1 million in new ARR. Our total ARR was approximately 10 -- I'm sorry, $1.58 billion, up 9.1% and organically grew 11.5%. Since Q4 of last year, SaaS revenues now exceed our maintenance revenues.
Operating margins in the quarter were once again pressured by the acceleration of the shift to the cloud in the new business and the related decline in license revenues. As we've previously stated, we expect operating margin to trough in 2023 and to return to a trajectory of margin expansion in 2024. As we also discussed last quarter, merchant and interchange fees from our payments business under the gross revenue model have a meaningful impact on our overall margins. In Q1, we paid merchant fees of approximately $42 million. If those fees were netted out of both revenues and cost of revenues, our consolidated non-GAAP operating margin for the quarter would have been approximately 200 basis points higher.
Cash flow was robust this quarter with cash flow from operations of $74.7 million, up 39.5% and free cash flow of $63.6 million up 55.1%. As a reminder, cash flow for the balance of the year will be impacted by an estimated $131 million of cash tax payments resulting from the Section 174 tax changes, of which $73 million is related to 2022 taxes and $58 million is related to 2023 estimated taxes. We continue to strengthen our balance sheet as we repaid $120 million of floating rate term debt during the first quarter. We ended Q1 with total outstanding debt of $875 million and cash and investments of approximately $174.2 million.
Our net leverage at quarter end was approximately 1.52x trailing 12-month pro forma EBITDA. Our revenue and non-GAAP earnings guidance for the year are unchanged. Our 2023 guidance is as follows: we expect total revenues will be between $1.935 billion and $1.970 billion. The midpoint of our guidance implies organic growth of approximately 8%. We expect GAAP diluted EPS will be between $3.65 and $3.80 and may vary significantly due to the impact of stock option activity on the GAAP effective tax rate. We expect non-GAAP diluted EPS will be between $7.50 and $7.65. Interest expense is expected to be approximately $26 million including approximately $5 million of noncash amortization of debt discounts and issuance costs. Other details of our guidance are included in our earnings release.
I'd like to turn the call back over to Lynn.
