"Aric was phenomenal. He was immediately responsive to all of my requests, helped me clean up my books, and was flexible with the platforms I was already invested in. He completed every task--reconciling my accounts, filing my purchases, setting up new processes to keep clean books, etc--very quickly. "

Communications Consultant
"The catch-up and clean-up service was exactly what we needed. Aric untangled old transactions, fixed errors, and organized everything so we could move forward with a fresh start and real numbers we can trust.”
E.W.
Non-Profit Director
"...my bookkeeping was always a ‘when I have time’ project that never really got done. Now, with his flat monthly service, I don’t worry about it at all. He reconciles my accounts, organizes my expenses, and sends helpful summaries each month so I can see how the business is really doing. I love that the flat monthly fee makes budgeting straightforward, and Aric’s fast response times mean I always get answers and support when I need them.”
