Dental CPA firm vs fractional CFO: which does your practice need?
TL;DR: A dental-specialized CPA firm handles tax compliance, entity structure, and depreciation strategy. A fractional CFO handles forecasting, hiring economics, location expansion, and exit prep. They solve different problems and most growing dental practices over $2M in revenue end up needing both. Below: scope, cost, and how to sequence the hires.
Option A
Dental CPA
Specialty-trained CPA who focuses on dental and adjacent healthcare practices. Handles tax filing, entity structure (S-corp, PLLC), depreciation strategy on equipment, retirement plan design, and proactive tax planning. Often also coordinates with your bookkeeper.
Option B
Fractional CFO
Strategic finance leader engaged part-time, on a defined scope each month. Builds forecasts, models new associate hires, evaluates DSO offers, runs location expansion economics, and prepares the practice for any partner buy-in or exit transaction. Works alongside the CPA and bookkeeper, not instead of them.
| Category | Dental CPA | Fractional CFO |
|---|---|---|
| Annual cost | An annual fee for tax filing and basic planning, with advisory dental CPAs usually charging a monthly retainer on top. Rates vary by market. | From $48,000/yr (Sorso fractional CFO starts at $4,000/mo) — a fraction of a full-time CFO's loaded cost. |
| Primary scope | Tax compliance, entity structure, depreciation, retirement plans, S-corp reasonable salary review, year-end planning | Financial forecasting, KPI reporting, payer mix and case mix analysis, hiring economics, location expansion, transaction prep |
| Time horizon | Annual cycle plus quarterly check-ins. Heavy lift around year-end and tax filing season. | Monthly and forward-looking. Reviews monthly close, reforecasts quarterly, and ties weekly decisions to the financial model. |
| Specialty knowledge | Deep on dental tax structures, equipment depreciation, associate vs partner taxation, and dental-specific retirement plans (cash balance, 412(e)(3)). | Deep on dental practice economics: hygiene production, fee schedules, payer mix, associate ramp, multi-location overhead allocation, DSO valuation. |
| Decision support | Tax-driven decisions. Should we form a separate equipment-holding entity? Is now the right time to elect S-corp? What is our reasonable comp number? | Operating and capital decisions. Should we hire another associate? Buy or lease the new operatory? Open location two? Sell to the DSO at the offer they made? |
| Reporting | Annual financial statements (compilation or review), tax returns, supporting schedules. Limited operational reporting. | Monthly KPI dashboard, financial forecast, scenario models, board or partner-meeting materials. |
| Coordination with bookkeeper | Reviews bookkeeper output for tax accuracy. Usually quarterly or year-end. | Works with bookkeeper on month-end close timing, chart of accounts structure, and ensures KPI reporting can be built on top of clean books. |
| When you can wait | Almost never. Every practice needs a CPA at minimum for tax filing. Dental-specialized usually pays for itself once your collections and tax complexity outgrow a basic solo setup. | Until roughly $2M-$3M in revenue. Below that, the strategic complexity may not justify $4K+/mo. Above that, the lack of a CFO function starts costing more than the CFO would. |
| Best for | Every dental practice. The question is whether to use a generalist CPA or a dental specialist (almost always specialist once the practice has real scale). | Dental groups doing $2M+ in collections, growing through associates or locations, considering DSO transactions, or planning partner buy-ins or transitions. |
A dental CPA handles tax. A fractional CFO handles strategy. Most growing practices need both.
These are not competing choices; they are different jobs. Your dental CPA makes sure you are filing correctly, structuring tax-efficiently, and not leaving money on the table at year-end. Your fractional CFO makes sure the next associate hire pencils out, the second location has a real path to break-even, and the DSO offer on your desk is fair. A dental CPA without a CFO function leaves growth decisions to gut feel. A fractional CFO without a tax-savvy CPA can build the right operating plan and still overpay in tax. For most dental practices over $2M in collections, the right setup is a dental-specialized CPA for tax and a healthcare-focused fractional CFO for the operating and capital decisions.
Frequently Asked Questions
Can my dental CPA also act as my CFO?+
Sometimes, in small practices. A dental CPA who actively does monthly review, KPI reporting, and forecasting can effectively cover both functions for a $1M-$2M solo practice. Above that, the time required to do real CFO work usually exceeds what a CPA's hourly rate makes practical inside a tax-driven engagement. The hourly rate also makes ongoing strategic work expensive when billed à la carte.
Will my dental CPA and fractional CFO step on each other?+
Not if the scopes are written cleanly. A normal split: CPA owns tax, entity structure, retirement plans, and year-end. CFO owns monthly close oversight, KPI reporting, forecasts, hiring and expansion decisions, and transaction prep. They share the chart of accounts and the bookkeeper. Quarterly joint check-ins keep both aligned.
Which should a $1.5M solo practice hire first?+
Dental CPA first. At $1.5M, the upside from tax planning usually exceeds the upside from CFO work, and a dental-specialized CPA can cover light advisory work. Add a fractional CFO when you start adding associates, opening a second location, or seriously evaluating DSO offers.
Do fractional CFOs evaluate DSO offers?+
Yes, and this is one of the most common engagement triggers. A healthcare-focused fractional CFO will normalize your EBITDA, build the add-back schedule, benchmark the offer against comparable transactions in your market, and walk you through what the deal actually means for your earn-out and post-close ownership. Skip this step and you negotiate the offer without knowing what your EBITDA is really worth.
Is a fractional CFO useful if I have no plans to expand or sell?+
Yes. The most underrated value is in steady-state decisions: pricing, payer renegotiation, comp redesign, schedule density, and operational discipline. Practices with no growth ambition still benefit from monthly KPI clarity and a forecast that flags a problem before the bank balance does.
