Comparison
Fractional CFO vs CPA, bookkeeper, full-time CFO, or DIY?
For an owner-operated practice, a bookkeeper records what happened, a CPA keeps you compliant and files taxes, and a fractional CFO looks forward at profit, cash, and exit value for $3,500 to $7,500 per month. A full-time CFO does the same forward-looking work but costs far more and only makes sense above roughly $20M in revenue. Most $1M to $10M practices need all three of the recording layers plus a fractional CFO on top, not a single hire that tries to do everything.
Fractional CFO vs CPA: what is the difference?
Your CPA looks backward to keep you compliant and file taxes, usually a few times a year. A fractional CFO looks forward at pricing, margin, cash, hiring, and exit value, working with your numbers every month. They are different jobs, and the two roles work together rather than replace each other.
- A CPA's core deliverables are the annual return, compliance, and tax filings, typically backward-looking.
- A fractional CFO's core deliverables are a forward forecast, profit by service line, and a monthly decision package.
- A practice can keep its existing CPA and add a fractional CFO; the CFO coordinates with the CPA on tax strategy.
Takeaway: A CPA tells you what happened for the IRS; a CFO tells you what to do next for the business.
Top Practice CFO is the forward-looking layer that sits on top of your CPA, with every number computed from your ledger and reviewed by a CFO.
Fractional CFO vs bookkeeper: what is the difference?
A bookkeeper records and categorizes transactions so your books are accurate and current. A fractional CFO uses those clean books to forecast cash, find margin, and guide decisions. The bookkeeper is the foundation; the CFO is the strategy built on it, and you generally need both.
- Bookkeeping cost for an owner-operated practice typically runs a few hundred to about $1,500 per month, depending on volume.
- A fractional CFO requires clean books as an input and does not replace the bookkeeping function.
- Without accurate books, a forecast is unreliable, so the two functions are sequential, not interchangeable.
Takeaway: Bookkeeping is the data layer; the CFO is the judgment layer that turns that data into decisions.
Top Practice CFO can run alongside your bookkeeper or fold bookkeeping in, then build the forecast and KPI scorecard on top of accurate books.
Fractional CFO vs full-time CFO: which should a practice hire?
A full-time CFO and a fractional CFO do the same forward-looking work, but a full-time hire costs roughly $180,000 to $250,000 per year in total compensation before benefits, while a fractional retainer runs $3,500 to $7,500 per month. Below about $20M in revenue, most owner-operated practices do not have enough finance work to justify a full-time salary. Fractional gives you senior-level judgment at the fraction of hours the practice actually needs.
- Full-time CFO total compensation: roughly $180,000 to $250,000 per year, more once benefits and bonus are included.(Business Talent Group market context)
- Fractional CFO retainer in this market: $3,500 to $7,500 per month, a defined scope rather than a salaried seat.
- Demand for fractional CFOs has risen sharply since 2020 as smaller businesses access senior finance talent part-time.(Business Talent Group)
| Option | Approximate annual cost | Best for |
|---|---|---|
| Fractional CFO retainer | $42,000 to $90,000 | $1M to $10M owner-run practices |
| Full-time CFO | $180,000 to $250,000 plus benefits | $20M-plus groups with constant finance work |
Takeaway: Under about $20M in revenue, fractional delivers the same role for a small share of the cost.
Top Practice CFO is built for the $1M to $10M owner-operated practice that needs CFO judgment but not a full-time CFO salary.
When is DIY or spreadsheets enough for a practice?
DIY works while the practice is small, the owner has time, and the questions are simple, such as basic monthly profit and a rough cash check. It stops being enough once you need profit by service line, a rolling 13-week cash forecast, provider compensation analysis, or you are weighing an acquisition or exit offer. At that point spreadsheets become slow, error-prone, and hard to trust for real decisions.
- DIY cost is the owner's time plus software, but the hidden cost is missed margin and decisions made on stale or incomplete numbers.
- Spreadsheets lack version control and audit trails, so errors compound and forecasts drift from the ledger.
- Quality CFO engagements often surface $100,000 to $300,000 in recoverable cash, margin, or tax in the first 90 days (illustrative range).
Takeaway: DIY is fine until a wrong number costs more than the help would have.
Top Practice CFO starts with a fixed-scope 14-Day Financial X-ray, so you can see what DIY is missing before committing to a retainer.
Which option is right for my practice at $1M to $10M in revenue?
Most owner-operated practices at this size keep a bookkeeper for accurate books and a CPA for tax and compliance, then add a fractional CFO for the forward-looking strategy. A full-time CFO is usually premature below roughly $20M, and pure DIY tends to leave margin and cash on the table once the practice gets busy. The pattern is layered: recording functions plus a fractional CFO on top, not one role doing all of it.
| Option | What it does | Cost | Best for |
|---|---|---|---|
| Bookkeeper | Records and categorizes transactions; keeps books accurate and current | A few hundred to about $1,500 per month | Every practice; the data foundation |
| CPA | Compliance and tax filing; backward-looking annual return | $1,500 to $5,000 per year for a practice return | Tax compliance and filing |
| Fractional CFO | Forecast, profit by service line, KPI scorecard, exit readiness; forward-looking | $3,500 to $7,500 per month | $1M to $10M owner-run practices |
| Full-time CFO | Same forward-looking work, full-time and in-house | $180,000 to $250,000 per year plus benefits | $20M-plus groups |
| DIY or spreadsheets | Owner builds basic profit and cash views by hand | Owner's time plus software | Early-stage or very simple practices |
Takeaway: At $1M to $10M, the answer is usually bookkeeper plus CPA plus fractional CFO, not a single hire.
Top Practice CFO is the fractional CFO layer in that stack for owner-operated veterinary, med spa, and similar practices.
Frequently asked questions
- Can a fractional CFO replace my CPA or bookkeeper?
- No, and that is by design. The bookkeeper keeps your books accurate, the CPA keeps you compliant and files taxes, and the fractional CFO uses those accurate books to forecast cash and improve margin. We coordinate with both rather than replace them.
- Is a fractional CFO worth it under $1M in revenue?
- Often not yet. Below $1M, a bookkeeper plus a CPA and careful DIY usually cover the need. A fixed-scope 14-Day Financial X-ray is a low-risk way to test whether there is enough margin and cash opportunity to justify ongoing CFO work.
- At what revenue should I hire a full-time CFO instead?
- Usually around $20M in revenue or once finance work is constant enough to fill a full-time seat. Below that, a fractional CFO delivers the same role for a small share of the cost, which is why most $1M to $10M practices stay fractional.
