When does a medical practice need a CFO?
Most owner-operated medical practices need a fractional CFO around $5 million in revenue, once there are multiple providers or locations, when you can't see profit by provider or service line, when cash surprises you, or when a payer contract or a possible sale is on the table. Below that, and while the picture stays simple, a good bookkeeper still serves you better than a CFO. A fractional CFO gives you senior financial judgment at the level you actually need, without a full-time seat that runs $275,000 to $500,000 all-in.

01 · The signs
What are the signs your practice needs a CFO?
You rarely wake up one morning knowing it's time. It shows up as a pattern in how your Monday mornings feel. If several of these are true at once, the practice has outgrown recording the past and needs someone owning the future.
- 01
Your P&L is always looking backward
The statement lands on the 20th and tells you what happened six weeks ago. You're steering a growing practice on last month's numbers, with nothing that shows where cash and margin are headed.
- 02
You can't see which provider or line makes money
You know total revenue. You can't say which provider, location, or service line actually earns, or what a case costs you once every direct cost is attributed to it. In a multi-provider practice, that's where the real story lives.
- 03
Cash surprises you
You find out cash is tight when the balance drops, not 13 weeks out. Payroll and a quarterly tax payment land the same week and it catches you off guard, even though nothing went wrong clinically.
- 04
Big decisions still come down to gut feel
A new provider, a second location, a piece of equipment, or a payer renegotiation, and the numbers to decide it well aren't in front of you. Your bookkeeper records the past accurately, but nobody owns turning it into forward decisions.
- 05
A payer contract or a sale is on the table
You're renegotiating a payer contract, or private equity has come calling, and you need your own math before you sit down. Whoever is across the table will show up with better numbers than you have on your side.
- 06
You priced a full-time CFO and the math didn't work
Market rates run $275,000 to $500,000 all-in depending on company size, plus benefits and the job of managing the hire. At your revenue that seat is hard to justify, but the work it would do is real.
02 · The thresholds
What revenue and complexity thresholds actually matter?
Revenue is the number everyone asks about, but complexity is what really moves the line. Here is the honest version, so you can place your own practice on it.
Revenue
~$5M
Below roughly $5 million in revenue, a solid bookkeeper plus your CPA usually covers what you need. Around and above it, the cost of not seeing your numbers forward starts to exceed the cost of a fractional CFO.
Providers or sites
2+
One provider in one location is legible on a simple P&L. Add providers, locations, or service lines and a blended P&L hides exactly the margin differences you most need to see.
Complexity
Payer
Payer mix, denials, aging AR, and a code transition like the January 2026 arterial CPT change turn a simple practice into one where margin moves for reasons a summary P&L won't show.
On the horizon
Exit
If a sale is anywhere in the next few years, the work that makes a practice sellable is the same work that makes it more profitable to own, and it starts years before the offer.
None of these is a hard gate on its own. Read them together. A practice that clears the revenue floor but stays genuinely simple can wait, and a smaller practice with real complexity and a sale on the horizon usually shouldn't.
03 · Which role fits
Full-time CFO, fractional CFO, or still just a bookkeeper?
Still a bookkeeper
Under roughly $5 million, or simple and single-provider, a good bookkeeper plus your CPA is the right call. You need the past recorded well more than you need a CFO, and paying for one early rarely pays back.
Fractional CFO
The usual fit in the $5 to $50 million range. You get senior financial judgment, profit by provider and location, and a forward view of cash, at the level you actually need, without a full-time seat or the job of managing one.
Full-time CFO
Right once the practice is large enough and complex enough to keep a $275,000 to $500,000 seat busy, or when you already have a finance team that needs a leader. At that point you need a hire, not a fractional partner.
A fractional CFO also works alongside your bookkeeper rather than replacing them. For the full breakdown of who does what, see fractional CFO vs controller vs bookkeeper.
04 · How I answer this
Start with a diagnostic, not a hire
You don't have to guess whether it's time. The Margin Map is a fixed-scope, $7,500 diagnostic that runs in three weeks: your P&L rebuilt by provider, location, and line, a 13-week cash forecast, and a ranked opportunity list with a dollar value on every item. It tells you exactly what a CFO would be worth in your practice before you commit to one.
I'm an independent fractional CFO, paid only by you. No fee, commission, or referral cut from any private equity firm, buyer, or billing vendor. If the Map doesn't identify at least three times its fee in margin opportunities, you don't pay, and if you continue to a retainer the full $7,500 is credited to month one.
05 · Questions owners ask
When to hire a CFO: common questions
At what revenue does a medical practice need a CFO?
There's no hard line, but around $5 million in revenue is where it usually starts to make sense, and it's driven as much by complexity as by size. A single-provider practice at $6 million may still be fine with a bookkeeper, while a five-provider group at $5 million with denials and payer-mix questions needs the forward-looking layer a CFO builds. Below roughly $5 million, a good bookkeeper plus your CPA is usually the right call.
Do I need a full-time CFO or a fractional one?
Most practices in the $5 to $50 million range need the judgment of a CFO but not a full-time seat. A full-time CFO runs $275,000 to $500,000 all-in depending on size, plus benefits and the work of managing them, and a first hire has often seen exactly one practice: yours. A fractional CFO plugs in at the level you actually need, brings a wider pattern of what works, and costs a fraction of the seat.
Isn't my bookkeeper or controller enough?
Keep them. Bookkeepers and controllers record and reconcile what already happened, and good ones are worth every dollar. What's usually missing is the forward-looking layer: profit by provider and location, a rolling 13-week cash forecast, and the handful of numbers that drive margin. A fractional CFO builds that layer and works through your bookkeeper, not around them. In most engagements the books end up more useful, not the bookkeeper less so.
Can't my CPA do this?
Ask them. Most CPAs are excellent at tax and compliance and will tell you straight that forward-looking margin and cash work isn't their lane. If yours does offer it, compare deliverables: a rebuilt P&L by provider or line, a 13-week cash forecast, and a prioritized opportunity list, kept current, not filed once a year.
How do I know if it's worth the cost before I commit?
Start with a diagnostic instead of a hire. The Margin Map is a fixed-scope, $7,500 engagement over three weeks: your P&L rebuilt by provider and location, a 13-week cash forecast, and a ranked opportunity list with a dollar value on every item. If it doesn't identify at least three times its fee in margin opportunities, you don't pay. You find out what a CFO would be worth in your practice before you take on a retainer.
My practice is under $5 million. What should I do instead?
Get a strong bookkeeper and a CPA you trust, and keep your chart of accounts clean enough to answer basic owner questions. At that stage the forward-looking layer matters less than getting the fundamentals recorded well, and paying for CFO-level work is usually premature. When revenue and complexity grow into the range above, the numbers you kept clean make the CFO work faster.
