A cost-effective back office built for growth
BBOS was founded on a simple belief: small and mid-sized businesses deserve the same quality back-office infrastructure as large corporations — without the overhead of a full in-house team.
We offer fully remote services tailored to fit your workflow, your systems, and your team. Whether you need full back-office outsourcing or targeted support for a specific function, we adapt to you.
BBOS is a proud winner of the New York Rangers “No Quit in Small Business” Award and a longtime supporter of Force Blue, Kelly’s K9s — Tails of Courage, and Hasbara Fellowships.

HR health check
Once in a while you stumble across the ever elusive bookkeeper who is honest, hardworking and committed to earning your trust and doing a good job. When you find one of that bookkeeper, they will be your last.
It has taken me years to find Bari Jamnik and Bookkeeping & Back Office Solutions. Since we began working with Bari and her colleagues, we have felt taken care of. And we have rested a little easier at night. Mostly we have felt as though BBOS is interested in having clients for life. Not just a monthly recurring fee.
Our business is small. Our margins are tight. Our success hinges upon the leanness and the clarity of our books. Bari has been instrumental in that care, and we are grateful.
Should anyone like to contact us for a more personal testimonial about Bari and BBOS we are more than willing to comply.
