Testimonials
Rave reviews from companies like yours.
Extremely personable
I used Bay Business Group to prepare my personal and LLC taxes for 2010. They were extremely personable and informative throughout the entire process. I’ll be using them again in a few weeks.

Highly recommend
Highly recommend their services. We have been using Bay Biz accounting and Bookkeeping and tax filing services for more than 10 years as a government contractor and have undergone a DCAA audit for our accounting system with no findings. We have grown and made it on the Inc. 5000 list of fastest growing companies in the US four years in a row and have retained their services through our growing journey. Mary is very knowledgeable and responsive with everything government contracting and is up to date with the latest rules and regulations and compliance with tax law. Jackie has been a pleasure to work with to keep our Bookkeeping up to date. They are very professional and responsive and dependable.

Five stars!
I’ve been working with Bay Business Group for over a decade. The support my bookkeeping, company taxes, payroll and a variety of other critical functions. I can confidently say they are five stars across the board. I work specifically with Mary L as my CPA and Cathy C as my bookkeeper and payroll office. They are readily available whenever I need them and are highly skilled in their work. I trust them to provide sound advice along with way too with my business financials. One of the best business decisions I have made is working with Bay Biz
