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.
