We started working together in August 2022 and since then I had only great experiences with all the team members. Jordan Burnham, Cassiopeia Coloma, Emil Natura, and Tracy Howell to name the most notable ones (in a chronological order of getting to know each person).
What I value a lot in our partnership is that I am sure our accounting and taxes are done right and I can focus my attention on developing our product and taking care of our users.

“I’ve been through 10 bookkeepers in 16 years, indinero is the best we have worked with, and there is no close second. They are the first bookkeeper who successfully set us up for accrual bookkeeping. That seems a real struggle for food service companies because it is a lot of work.”
