Who you actually need, and when
A tax-ready P&L will not tell you which clinicians are profitable. That is a different job, and most practices never hire for it.
The three finance roles, and what each actually does.
A bookkeeper records transactions and runs payroll. A controller owns accuracy: monthly close, revenue split by payer, deferred program revenue carried correctly, and contractor versus employee cost tracked cleanly. A CFO looks forward: modeling clinician hires against the credentialing gap, forecasting cash, and preparing the practice for growth or sale.
Five questions a generalist bookkeeper usually cannot answer.
- What is our margin per clinician?Requires collected revenue attributed by clinician against their full loaded cost, including supervision.
- What is our utilization rate?Requires practice management scheduling data reconciled against billed sessions.
- Which payer pays us slowest?Requires collections and days-to-payment tracked by panel rather than one AR balance.
- What will the next hire cost us before they bill?Requires modeling the credentialing gap against cash. This is CFO work.
- Are we exposed on contractor classification?Requires someone who recognizes the pattern and raises it, which a transaction-coding role generally will not.
Rough thresholds
A solo practitioner needs accurate bookkeeping and little else. A group of three to eight clinicians needs controller-level rigor, because payer mix, contractor arrangements, and utilization differences have become the main drivers of profit and none of them are visible in standard financials.
Beyond roughly eight clinicians, or at the point of adding a location, a program line, or considering a sale, forward-looking work becomes necessary. Group practice economics are unforgiving: a few points of utilization across a team is the difference between comfortable and struggling.
The classification issue deserves a named owner
Contractor misclassification is common in group mental health practices and the exposure is real — back taxes, penalties, and in a sale, a diligence finding that reduces the price or blocks the deal. It rarely surfaces from a bookkeeping function, because coding a payment correctly and classifying a worker correctly are different questions.
Someone should own it explicitly, review the arrangements against the actual working relationship, and document the reasoning.
Frequently asked.
When does a mental health group practice need a controller?
Usually somewhere around three to eight clinicians, when payer mix, contractor arrangements, and per-clinician utilization become the main drivers of profit. At that point standard financials stop being sufficient because none of those drivers appear in them.
Can a general bookkeeper handle a therapy practice?
They can record transactions and run payroll accurately. What they typically will not do is attribute revenue and cost by clinician, reconcile scheduling data against billed sessions, carry program revenue as deferred, or flag contractor classification risk — which is most of what makes the numbers useful.
What does a fractional CFO do for a mental health practice?
Models clinician hires against the credentialing gap and available cash, forecasts collections by payer, reports contribution margin per clinician, and prepares the practice for expansion or sale. The work is forward-looking, which is precisely what bookkeeping is not.
