Expanding the impact
Our Bookkeeping Philosophy
Many bookkeeping firms compete on accuracy, timeliness, or QuickBooks proficiency.
Great bookkeeping produces decision-ready data, is consistent month to month, and integrates cleanly with tax, payroll, and advisory.
- Large-team redundancy
- Future-focused work
- Much more than keeping books clean

Testimonials
Rave reviews from companies like yours.
simply awesome
I was referred to Bay Business Group in 2010 after another CPA made (very costly) mistakes on my 2008 and 2009 Federal and State Returns. Mary Leighty (CPA) has done my taxes since 2010 and I could not be more satisfied. Her work is simply awesome and her communication skills and responsiveness have taken all the stress out of tax preparation season. Thanks Mary!!!

"go to" folks!!
Bay Business has done all of our accounting for almost 20 years. They are a wonderful company to deal with. They are responsive, extremely helpful and friendly and I would add, never make us feel like we are unreasonable when we make special requests. We deal mostly with Mary and Valerie and they are great “go to” folks!!
