St. Louis Bookkeeping for Small Business Owners
Bookkeeping is the least interesting thing your business needs and the one that breaks everything else when it slips. Nobody starts a company because they were excited about reconciling accounts. Then a lender asks for financials, and eleven months of receipts are sitting in a shoebox.
Thompson Flaherty handles monthly bookkeeping for small businesses across the St. Louis metro, with CPAs reviewing the work rather than only a data-entry service.

What Our St. Louis Bookkeeping Service Covers
Underneath all of it, a CPA reviews the file. That’s what separates bookkeeping services from each other, because clean-looking books can still be wrong in ways only someone who prepares returns will catch.
Why Bookkeeping and Tax Should Sit With the Same Firm
Here’s the pattern we see constantly. A business uses one company for bookkeeping and a separate CPA for the return. In March the CPA opens the file, finds the owner’s distributions coded as payroll expense and a vehicle purchase sitting in repairs, and spends billable hours cleaning up twelve months of decisions nobody flagged at the time.
We took on a client whose books had been maintained faithfully all year by a bookkeeper who had never seen a tax return. Loan principal payments were being run through as expenses. The books balanced perfectly and the profit figure was meaningfully wrong, which meant every quarterly estimate that year had been calculated off a number that was not real.
When the same firm does both, the person entering the transaction knows how it lands on the return. Nothing needs unwinding in March. Our St. Louis tax accountant work and the bookkeeping run out of the same file.


Do I Need a Bookkeeper or an Accountant?
They are different jobs and most growing businesses eventually need both.
The reason we bundle them is that the second job is only as good as the first. Planning built on unreliable books is guesswork with a nicer font. See our St. Louis CPA services and our monthly accounting work.
Signs Your Books Need Attention
None of this is unusual and none of it is a reason to be sheepish about the state of things. It’s a reason to fix the foundation before building anything on it.
Which Software Do You Work With?
We work primarily in QuickBooks Online and Xero, which covers most St. Louis small businesses. If you are on something else, tell us and we will let you know honestly whether we can support it well.
We do not force a migration for the sake of it. If your current setup works, we work in it. If it is genuinely holding you back, we will explain why and let you decide.
Where We Serve
Bookkeeping runs virtually by nature, so location matters less here than it does elsewhere. Being local matters when you want to sit across a table and go through the numbers, and Edwardsville is a short drive from most of the metro.
