The three finance roles, and what each actually does.
A bookkeeper records transactions, reconciles accounts, and runs payroll. A controller owns accuracy: monthly close, hygiene isolated as a profit center, membership plans carried as deferred revenue, and equipment capitalized properly. A CFO looks forward: modeling the associate hire, the equipment purchase, the second location, and eventually the DSO conversation.
Five questions each role can answer
- What is our hygiene department margin?Requires hygienist wages and hygiene production separated from general totals.
- What is our unearned membership balance?Requires plan fees carried as a liability rather than booked at enrollment.
- What is our true overhead percentage by component?Requires a chart of accounts built for dental rather than for a generic small business.
- What is our profit-to-cash bridge?Requires reconciling net income against principal payments and capital purchases. Rarely produced by a bookkeeping function.
- What would a DSO actually pay us?Requires normalized adjusted EBITDA and an understanding of how buyers adjust. This is CFO work.
Rough thresholds
A single-dentist practice under roughly $800,000 in collections generally needs correct, dental-aware bookkeeping. Between roughly $800,000 and $2 million, controller-level rigor matters, because membership plans, equipment capital, and hygiene economics have become material enough to distort the picture if handled loosely.
Above roughly $2 million, or when adding an associate, a second location, or fielding acquisition interest, forward-looking work becomes necessary. The decisions are large enough that modeling them beforehand is cheaper than learning from them.
The DSO conversation starts years early
Practices that get approached by a DSO and then start cleaning up their books are negotiating from the wrong position. The adjusted earnings figure a buyer values is built from trailing financials, so cleanup done after an approach shows up as a series of adjustments the buyer gets to argue with.
Two to three years of normalized owner compensation, separated personal expenses, correctly handled membership deferrals, and documented systems produces a number that survives review. Whether you sell or not, the same work makes the practice easier to run.
Frequently asked
When does a dental practice need a CFO?
Typically around $2 million in collections, or earlier at the point of a major decision, adding an associate, opening a second location, a large equipment purchase, or responding to DSO interest. The trigger is the size of the decision rather than the size of the practice.
Can a general bookkeeper handle a dental practice?
They can record transactions accurately, but most will not isolate hygiene as a profit center, carry membership plans as deferred revenue, or capitalize equipment correctly unless specifically asked. Those are the things that make dental financials useful rather than merely correct.
Should I hire in-house or outsource dental accounting?
A full-time in-house controller is rarely full-time work in a single-location practice. The common structure is an in-house office manager handling day-to-day with outsourced controller and CFO capacity layered on, which gives access to dental-specific expertise without a full salary.
