How We Power Your Finance & Bookkeeping

A full-time bookkeeper costs $45,000–$65,000 per year, takes 6–8 weeks to hire, and still needs supervision, sick days covered, and software licensing. Outsourced bookkeeping and accounting services from Ossisto deliver the same - or better - output at a fraction of the cost.

Frequently Asked
Questions

Questions worth answering before you sign up.

Do you offer accounting and bookkeeping services for small businesses specifically?

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.

How much do accounting and bookkeeping services cost?

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.

Can you manage bookkeeping on a daily basis?

Yes. We can handle daily transaction recording, categorization, reconciliations, and other routine bookkeeping activities to keep your financial records accurate and up to date.

Can you work with our existing accounting software?

Yes. Our team can work with a range of accounting and financial platforms, including QuickBooks, Xero, Zoho Books, NetSuite, and other business-specific systems.

Can your services scale as our business grows?

Yes. Our outsourced accounting services are flexible and can scale with your business, whether you need basic bookkeeping support or a complete accounting function.
