Why FlowBooks exists

Built to solve a real small-business problem

FlowBooks started when Kate T. was running a small bookstore and could not find accounting software that was both simple and affordable. Most options were either overly complex or required paying SaaS subscriptions forever.

Her husband Mike, an engineer, decided to build the solution they could not find: practical accounting software with classic workflows and ownership-based pricing.
