Accounting service vs fractional CFO: which does your clinic need?
TL;DR: These are two layers, not two options, and the order matters. Almost every clinic needs accurate healthcare accounting first: clean books, a real monthly close, and billing data tied to the P&L. A fractional CFO is the layer you add on top once the decisions get expensive, such as hiring providers, opening a location, taking on debt, or preparing to sell. Accounting tells you what happened and where the money is leaking; a CFO uses those numbers to decide what to do next. Below: scope, cost, and the point where most clinics add the CFO layer.
Option A
Monthly accounting service
Ongoing bookkeeping, reconciliation, and monthly reporting built for medical practices. Closes your books, ties billing data to the P&L, and gives you accurate location-level and payer-level numbers every month. This is the foundation every clinic needs before anything else.
Option B
Fractional CFO
Part-time senior finance leadership layered on top of clean books. Forecasting, cash-flow planning, expansion and financing analysis, and exit preparation. A CFO does not replace your accounting; it uses those numbers to make forward-looking decisions.
| Category | Monthly accounting service | Fractional CFO |
|---|---|---|
| Core question it answers | What happened last month, and where is money leaking? Are the books accurate and the numbers real? | What should we do next? Can we afford this hire, this location, or this loan, and what will it do to cash? |
| Scope of work | Bookkeeping, monthly close, financial statements, billing-to-books reconciliation, benchmarking, and a short monthly action list. | Forecasting and budgeting, cash-flow planning, scenario and expansion analysis, financing and lender prep, KPI dashboards, and exit or sale readiness. |
| Time horizon | Backward- and present-looking. Keeps the financial record straight and current. | Forward-looking. Turns the record into decisions about the next 12-36 months. |
| Typical monthly cost | Sorso's healthcare accounting starts at $2,000/mo for a single-location clinic with full close, location-level P&Ls, and KPI reporting. | Sorso's fractional CFO starts at $4,000/mo, plus a one-time onboarding fee of $3,000-$9,000 depending on how much cleanup the books need. |
| When a clinic needs it | Essentially from day one. Any practice with more than a handful of monthly transactions needs accurate books; healthcare-specific accounting matters once billing data drives the real picture, which Sorso puts at roughly $0.5M+ in revenue. | When the money decisions get big and hard to reverse. Sorso positions fractional CFO for clinics at $3M+ in revenue, a second location, active growth, financing, or a planned exit. |
| What it does not do | Does not make the forward decisions for you. It produces accurate numbers; deciding what to do with them is a different job. | Does not do the daily bookkeeping or the monthly close. A CFO needs clean books to work from, or the output is built on guesses. |
| Can you have one without the other? | Yes, and most clinics start here. Accounting stands on its own. | Not really. A fractional CFO on top of missing or messy books spends the engagement fixing data instead of driving decisions. Accounting comes first. |
Start with accounting. Add a CFO when the decisions get expensive.
Think of these as two layers rather than two options, and the order matters. Almost every clinic needs accurate healthcare accounting first: clean books, a real monthly close, and billing data tied to the P&L. Without that foundation, a fractional CFO spends the engagement cleaning up numbers instead of using them. Add the CFO layer when the decisions in front of you are big enough to justify it: hiring providers, opening a second location, taking on debt, or preparing to sell. As a rough line, most clinics run on accounting alone until around $3M in revenue or a second site, then add fractional CFO support. If you only ever need one of the two, it is the accounting.
Frequently Asked Questions
Do I need both accounting and a fractional CFO?+
Eventually many clinics do, but rarely at the same time. Start with accounting; it is the foundation. Add a fractional CFO when you are making decisions the numbers alone do not answer: whether you can afford a new provider, whether a second location will pay off, how a loan changes your cash position. Below roughly $3M in revenue, most clinics run well on healthcare accounting alone.
Can a fractional CFO also do my bookkeeping?+
A CFO can, but it is expensive and backwards. CFO time is priced for strategy, not for reconciling bank feeds. The efficient structure is a monthly accounting service doing the close and a fractional CFO using that output to plan ahead. At Sorso the two are sold separately or together, so you add the CFO layer only when you actually need it.
What does each one cost at Sorso?+
Healthcare accounting starts at $2,000/mo for a single-location clinic with full close, location-level P&Ls, and KPI reporting. Fractional CFO starts at $4,000/mo, plus a one-time onboarding fee of $3,000 to $9,000 depending on how much cleanup the books need. You can start with accounting and add CFO support later without switching firms.
We already have a CPA. Does that cover the CFO part?+
Usually no. A CPA files your taxes and keeps you compliant, which is essential but backward-looking and mostly annual. A fractional CFO works from your monthly numbers to make forward decisions about hiring, expansion, financing, and exit. They are complementary jobs, and most growing clinics keep their CPA for tax while adding accounting and, later, CFO support for the operating decisions in between.
