Frequently Asked
Questions

Questions worth answering before you sign up.

Yes - small businesses are Ossisto's primary customer. Our Essentials plan at $299/month is purpose-built for small businesses with straightforward needs: monthly reconciliation, P&L, accounts payable/receivable, and a year-end CPA-ready package. We understand that small businesses need professional-grade accounting without the overhead of a full-time hire, and that's exactly what we provide.
Ossisto plans start at $299/month for small businesses with up to $50k/month in revenue, and $549/month for the Growth plan (up to $250k/month). This compares to $45,000–$65,000 per year for a full-time in-house bookkeeper - meaning most Ossisto clients pay between 70–85% less for the same or better level of service. All plans are monthly with no contracts.
