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.
