Bookkeeping

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

Number savvy
We love Bay Business- they handle so much for us and I trust them to take care of our small business accounting needs. They always go the extra mile and are also friendly and kind when talking with people who are not number savvy.

Outstanding
This is my second venture and second time with BayBiz and I wouldn’t have come back if their service wasn’t outstanding. I use them for their suite of services and David is always available if needed but Kerry and Mary do such a great job, I almost never need to bother the boss. Highly recommended if you want to spend more time doing business and less time on back office activities.

Meaningful & timely
By partnering with Bay Business Group, they have streamlined my accounting operating procedure, accounting operation, and given me meaningful & timely monthly reporting. This in return gives me quicker problems resolutions as they arrive. Bay Business Group has been proactively suggesting improvement to accounting reporting, interpretation of accounting reports and improvement to the accounting system. Giving me a way to measure the performance of my business and more time to work and tweet improvement to my business operation and product lines.

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!!!
