Who runs the numbers in a medical practice: bookkeeper, controller or CFO
Updated 16 October 2026
Every practice has a finance function, whether one person or three people do the work. A bookkeeper records each transaction. A controller checks that the records are complete and correct and closes each month on a fixed date. A chief financial officer (CFO) uses the closed figures to plan and to decide. Each role depends on the one below it. This page sets out what each role produces, the signs that a practice needs the next one, and the ways to staff it. Some examples use clinic figures from franchise brands' Franchise Disclosure Documents (FDDs), the disclosures a franchisor gives a buyer before a sale.
Three roles and what each one produces
| Role | Work | Output |
|---|---|---|
| Bookkeeper | Records transactions, pays bills, runs payroll entries, reconciles bank accounts | Current books and basic reports |
| Controller | Designs the chart of accounts, runs the month-end close, manages cash, prepares year-end records | Monthly statements a lender or buyer can rely on, and budget comparisons |
| CFO | Forecasts, builds scenarios, plans capital, supports payer negotiations, prepares for a sale | Decisions backed by a model, and reporting for owners or a board |
The chart of accounts is the list of categories every transaction is coded to. When it follows the way the practice runs, by service line, location and provider, the monthly statements answer the owners' questions without extra work.
Medi-Weightloss's FDD reports cost of goods as one line that bundles labs, medications, supplements, injections, insurance billing and card fees. A Medi-Weightloss clinic that codes those items to one account cannot see a medication price change inside its 19.2% cost of goods ratio. Medi-Weightloss's compensation line also excludes the owner's pay. A Medi-Weightloss owner's chart of accounts needs separate accounts for each of those items before the clinic's figures compare with the brand's.
The controller's monthly checks
The controller closes the books by a set day each month. The close includes bank and card reconciliations, payroll accruals, deferred revenue for prepaid care, and a review of every line against prior months. An accrual is an entry that records a cost or revenue in the month it belongs to, before the cash moves. The controller flags any line that moved outside its usual range and finds the cause before the statements go to the owners.
The Joint Chiropractic's FDD includes a profit and loss for 492 clinics. The insurance line at those Joint Chiropractic clinics averaged $7,898, with a high of $48,870 and a low of minus $518, which means at least one clinic booked a refund. A controller reviewing a Joint Chiropractic clinic's insurance line against that $7,898 average would flag a figure near the high end and ask for a new quote.
What a CFO adds
A CFO works from closed books and asks what the figures mean for the next decision. The work covers forecasts, three-case scenarios, capital plans, payer contract analysis, preparation for a sale or a partner buy-in, and reporting to owners or a board. A practice needs this work when its decisions are too large to make without a model, or when a sale, recapitalization or other capital event is on the horizon.
Averan's reading of QC Kinetix's FDD puts break-even at about $697,052 of sales, which is 75.4% of the $924,273 average across 39 QC Kinetix clinics. That uses $542,073 of fixed cost and a contribution rate of 77.77% after supplies, franchise fees and card charges. A CFO for a QC Kinetix clinic would turn that break-even into a monthly sales target of $58,088 and a media budget to reach it.
Signs the practice needs the next role
Monthly statements arrive late, get restated, or leave the owners unsure of them. Nobody can say where cash will stand in 90 days. Nobody can name which providers or services make money. Every financial decision waits for the owner. A sale, a partner buy-in or a new loan exposes gaps in the records. Each of these signs means the practice is asking one role to do the work of the role above it.
HealthSource Chiropractic's FDD states a 7% royalty and a 2% ad fund. The expense data for 68 HealthSource Chiropractic clinics reports the royalty at 5.8% of revenue and the ad fund at 1.9%. A bookkeeper records the royalty invoice as billed. A controller or CFO for a HealthSource Chiropractic clinic asks which sales base the royalty is calculated on, because the answer changes the clinic's forecast.
In-house, fractional or a mix
A practice can staff finance three ways. An in-house hire suits a practice with enough work to fill the role full time. A fractional controller or CFO works for the practice on a set schedule for part of each month. A hybrid keeps a bookkeeper on staff and adds a fractional controller or CFO above that person. The choice depends on revenue, on the number of locations and entities, and on the owner's plans to grow, hold or sell.
Operational finance covers the books, the monthly close, the forecast and the decisions in between. For tax questions, talk to a CPA.
The figures are an illustration. A practice with three locations keeps one full-time bookkeeper who enters bills and payroll daily. A fractional controller works four days a month and closes the books by the tenth. A fractional CFO meets the partners once a month to review the forecast and once a quarter to update the budget. The practice has all three roles with one full-time finance employee on its payroll.
What this means for a practice owner
A bookkeeper records, a controller checks and closes, and a CFO plans. Each role relies on the one below it. The month closes by the tenth of the following month. The chart of accounts follows service lines, locations and providers. Owners get a one-page summary each month. Cash decisions use the forecast. A practice that sees late statements or unanswered cash questions needs the next role.
Getting the right role in place
Averan Advisors provides each role as a service. The bookkeeping service keeps the records current, the controller service closes the month and reports, and the fractional CFO service runs forecasts and decisions. The Medical Practice Numbers Check scores a practice's current figures.

- The call takes thirty minutesYou describe the business and where the numbers are letting you down. We give you an expert view of your situation, and what we would start with. There is no pitch deck.
- We look at the fileYou give us read access to the books as they are. We come back with what is wrong, what it will take to fix, and whether the answer is bookkeeping, controller work, or something else.
- We send a written scope and a priceIt lists what we do each month, what you get, the date it lands and the fee. We agree it before anything starts, and it does not change unless you agree.
- We take over the books and close the first monthWe set up access and systems and enter the opening balances. The first close lands on the date in the scope, and every one after it does too.
