Mary Ann Hair, CPA
Mary Ann Hair, CPA is a Houston accounting practice handling tax returns, bookkeeping, and CFO-level advisory for individuals, LLCs, and S-corporations. The firm keeps the work close, with the CPA on the account instead of handing it off.
The business
Mary Ann Hair, CPA is a boutique accounting firm based in Houston, serving Katy, Sugar Land, The Woodlands, and remote clients. The practice files individual, self-employed, LLC, and S-corporation returns and runs monthly and quarterly bookkeeping. It works with real estate investors, freelancers, and small business owners who want a CPA they can actually reach.
How AI works in the business
AI helps the firm sort receipts, categorize transactions, and flag items that need a second look before a return goes out. It drafts client summaries and surfaces deductions that are easy to miss across a busy filing season. The accountant stays in charge of every number; the AI just clears the busywork so there is more time for advisory.
The hardware behind it
The firm runs its AI on a private server from Texas Integrated Services, owned outright with no monthly cloud bill. Client tax data and financial records stay on hardware the practice controls, which matters for a business holding sensitive returns. There is no third-party platform reading the books.
Where it’s growing
The plan is to widen the bookkeeping side and take on more real estate and small business clients without adding overhead. As volume grows, the private server handles more of the document work in-house. Keeping the AI local means costs stay flat even as the client list gets longer.
