You're great at your trade. That's why you started your business. But being the best electrician, consultant, or security tech doesn't automatically make you great at running a company - and nobody teaches you that part.

Most clients come to me with a "books problem" and discover it goes a lot deeper. Balanced books don't tell you if your business is healthy - they just tell you the math checks out. One client thought she was doing fine because her books were clean. She was also bleeding $4,000 a month in unbilled time and had no idea.

Bookkeeping tells you what happened. We show you why it happened - and what to do next.

Sara - JNB LLC

Small business helping small business

JNB started because I kept meeting business owners who were intimidated by their own numbers - and they had no reason to be. They just needed someone to explain things in a way that made sense.

Some clients need a full financial transformation. Some just need someone to clean up QuickBooks so they can file taxes. I do both.

What I don't do is make you feel bad for not knowing this stuff already. Numbers didn't come naturally to me either - I figured it out because I had to, and now I help other people do the same.
