Thank you, Houston, and welcome, everyone. I'm proud of our team and the achievements that they have accomplished. And in the first quarter, they kept us on track to meet both our top and bottom line guidance for the year. Let me quickly go through a couple of our business lines.
Output Solutions had a solid start to the year with strong volume, both in mailings and electronic document delivery and increased profits in the quarter. Pieces mailed in the quarter were $8 million, and electronic documents delivered exceeded $19 million. However, a lot of the volume was on lower price per unit jobs. So revenues were understandably lower than the same quarter last year where revenues were unusually strong due to a lot of onetime jobs.
As we noted on our last call, our capabilities have been greatly enhanced by the investment in new printing and sorting machines and associated processes. This new equipment is one reason we once again delivered more electronic than paper documents for the second consecutive time in the first quarter, helping increase the volume while decreasing the cost of goods sold. [indiscernible] team have been breaking in the new machine while refining our processes to capitalize on the speed of the new machine and optimize overall efficiency and productivity. This will further position Output to capitalize on its increased capacity and processing speed. I expect Output to resume its growth in the second quarter while also continuing to reduce costs.
Turning to ACH, we saw a third consecutive quarter of recovery with electronic check transaction volume up 4%, return check transactions processed up 9%, and electronic check dollars process up 22%, all compared to the first quarter of 2023. PINLess debit also continues to exhibit strong growth.
In 2024, our year-over-year comparisons will be normalized since there is no longer any voyage or cryptocurrency noise in the comparable 2023 numbers. This will provide a clear view into the ongoing success of ACH where we have historically outperformed the industry growth rate.
But the real acceleration of ACH will come when we get our FedNow and the clearing house products in the market. We're not quite live yet but it's something that we're very close to. And just like every other part of our business, the sales pipeline in ACH is rich and there are abundant opportunities.
And finally, I wanted to congratulate Greg and his team for landing what could turn out to be the largest single program in the company's history. This is a large, exceptionally well-run ISV that has proprietary ERP system installed in hundreds of small, medium-sized and enterprise level businesses. While these businesses collectively generate over $6 billion a year in revenue, we believe that only accounts for about 23% debit and credit card payments. They also offer ACH payments. So that will be another opportunity for Usio.
The processing has a potential to double our annual card processing volume while adding $20 million or more in annual recurring revenue. Initial conversions are already underway, as Greg has discussed, we should start to see the program to contribute to our results soon with the significant ramp beginning later this year.
We won this business by demonstrating our ability to develop a program custom tailored to specifically meet their needs. As a result, the ISV will be notifying their merchants of the superior capability and providing them with the easy, convenient needs to convert their payment processing from their existing provider, which, in many cases, is Stripe Usio.
I also note that our strong financial position with over $7 million in cash at the end of the quarter, we're able to maintain our cash position over 3 months while significantly reducing payables and accruals. This provides us with the resources we need to make necessary investments to support our growth.
So overall, we had a very good start to the year. The first quarter came in essentially where we had internally projected it. With prepaid down as previously communicated, but strong volumes across the board and a new program added that could potentially be the largest in the company's history. And the pipeline remains rich, including a few megadeal prospects, which all were equate to $5 million or more in annual recurring revenue potential.
Consequently, I'm pleased to reaffirm our 2024 guidance. We expect revenue to be up between 10% and 12% for 2024, with the focus on enhancing operating leverage, we expect adjusted EBITDA to be between approximately $4 million to $4.5 million. In addition, we believe we will generate positive GAAP EPS in fiscal 2024.
With that, I would like to turn the call back to operator to conduct our question-and-answer session.
