Thanks, Ron. We had a strong Q1 to begin the year with a 17% year-over-year total revenue increase and a 21% increase year-over-year in our UCaaS service revenue. On top of the strong revenue numbers, we announced our exciting merger with NetSapiens that will add a strong increasing revenue -- recurring revenue stream, along with a tremendous UCaaS platform that currently exports north of 1.7 million end users. We also made significant investments in our UCaaS offerings and are prepared to launch our new Crexendo VIP platform this month that will enhance our current offerings with the concentration on VIP, which stands for video, interactions and phone. I believe this offering will be a game changer for us, and I will highlight more on that in a moment.
Our solid revenue growth year-over-year, despite the headwinds from the pandemic and slowdown in the economy is a testament to the strength of our UCaaS offering and the need for our work from anywhere capabilities that most businesses need to survive in today's new business environment. While our growth for the quarter did not produce GAAP income for the first time after 8 consecutive quarters, we expected that due to the nearly $700,000 in acquisition-related costs, combined with our investments made for our new Crexendo VIP offering and additional investments in our sales and support teams. Our non-GAAP net income of $308,000 or $0.02 per share continues to show that we are managing the business well as we continue to grow and improve.
The costs associated with our acquisition of NetSapiens are a significant investment in our future growth and our success. As you are aware, we have been spot on with following up on our plans. We're committed to managing a profitable business, and we're successful in that endeavor for 8 quarters in a row. We're committed to uplifting organically to a major exchange and completed that in July of last year with our listing on NASDAQ.
We're committed to raising funds to help our growth through accretive acquisitions, and we were successful with that with our S-1 offering in September. We're committed to using those funds to invest in strong acquisitions to help spur our growth and our offerings, and that commitment will be met shortly as we close on our merger with NetSapiens in the coming weeks.
The NetSapiens acquisition as a UCaaS platform provider that experienced 30% revenue growth from 2019 to 2020, along with tremendous growth in end users utilizing their platform, so a total over 1.7 million end users, and that propelled them to the fourth largest UCaaS platform provider in the U.S., according to a recent Frost & Sullivan report. Not only are we acquiring a strong and increasing revenue stream in a solid UCaaS platform, but we are also adding a terrific video collaboration tool that we will own as opposed to white labeling our current collaboration tool that has lower margins and less capabilities. We have already started marketing the new collaboration tool as Crexendo HD and have had great reviews and early success.
We are also extremely excited about working within the NetSapiens team. We are committed to ensuring that their platform is the best offering in the UCaaS industry and are committed to their partner community and our customers. The platform will be the core foundation for our Crexendo VIP offering, with the concentration on video with our collaboration tool, interactions with our strong suite of text, chat, messaging and factoring options and phones with our Crexendo-branded desktop phones with lifetime warranties, along with our cellphone capabilities for computers and our mobile phone applications for cellular and tablets, who will have an offering that customers, partners and resellers will all love.
As we integrate the 2 organizations, there are a lot of benefits that the combined company will recognize, including the aforementioned technology, along with a great personnel resources and industry experience that will help us maintain strong growth with healthy EBITDA and strong cash flow. We're excited to get the merger finalized and start implementing our combined plans, which are already in the designing stages and planning stages.
Until the merger is consummated, and afterwards, as a combined company, we will continue to manage our cost and reinvest in our organization. There's still tremendous opportunity in the UCaaS market and the need for work-from-anywhere solutions for businesses will only continue to grow and intensify. We are well positioned to take advantage of this growth as a stand-alone entity. But with the combination of Crexendo and NetSapiens, it will be a significant force to be reckoned with in the industry.
I'm excited about our past performance and even more excited about our future. We continue to execute on our plans and commitments for our shareholders, and our strategy for continued organic growth and growth through acquisitions will only gain more traction in the months and years ahead. With the opportunity to increase our market share, not only here in the U.S., but in the previously untapped international markets as well, we are positioned extremely nicely to deliver for our shareholders.
And with that, I will turn it back over to Steve for any additional comments.
