Sawgrass CPA
I have been very pleased with the addition of Unison staff for Tax and Accounting to our team. I am a very active member of the AICTP and I have been quite successful in transforming my firm from a traditional CPA firm to an Advisory firm, providing concierge level service and advanced tax reduction strategies to our clients.
Unison has played a huge role in allowing me to shift to this new model. The work is reliable, professional and they use clear workpapers and standardized procedures that are quite easy to review and follow. I highly recommend them.

It felt like magic. In less than a month, we were ahead on deadlines, our team wasn’t drowning, and I finally had time to think like a business owner again. The quality of work is outstanding, and they jumped right into our systems and processes. Despite losing a key employee during tax season, we didn’t miss a beat
