Clear numbers, calm decisions, & more time to build your business
About
STO Bookkeeping empowers start ups and small businesses by organizing their finances with accuracy and clarity. When your books are current and reliable, you can see what is really happening in your business and make decisions that support steady growth instead of guesswork.
Founded by Stephen Osinski, STO Bookkeeping grew out of a simple belief that owners deserve clear information and calm support, not confusing reports or rushed year end scrambles. Stephen combines practical bookkeeping skills with a focus on plain language, so you always know what your numbers are saying.
Most small business owners are carrying two jobs. One is the work they are great at. The other is trying to keep up with the books. STO Bookkeeping exists to take that second job off your plate and turn it into something that supports you instead of draining your time.
With STO Bookkeeping, You Get:
Structure
Support that's tailored to your business.
Transparency
Reports explained with clarity.
Organization
Clean books you can trust.

Meet Stephen Osinski
STO Bookkeeping is led by Stephen Osinski who has helped business owners move from “I do not trust these numbers” to “I know exactly what is going on.”
Stephen (you can call him Steve if you'd like!) combines technical bookkeeping skill with a calm, straightforward communication style. Clients come to STO Bookkeeping when they want their books handled with care and still want to talk with a real person.
I’ve always had a passion for numbers and having gained experience in many different fields, I knew that the accounting field was the right one for me. I find excitement in organizing numbers and explaining them in a transparent way. Even more exciting is helping owners of small businesses live out their dreams and passions and building relationships along the way!

I would 100% recommended STO Bookkeeping for your business. I'm a new business owner, and noticed that my QuickBooks wasn't always matching up with my bank transactions. I needed guidance and STO Bookkeeping provided that. Their service is professional, human-orientated and best of all, available when I needed it. Please don't hesitate to go with them.
