Where profit lives in a DSO structure

There is no single nationwide answer to “where the profit lives.” The answer starts with the lawful ownership and operating path in each state, then follows the actual contracts, services, cash, accounting, and tax treatment. In a licensed-owner state, outside investors may own the dental support organization (DSO) but not the professional interest in the dental practice. Another state may authorize lay ownership through registration or licensure, permit a capped non-dentist interest, or recognize an institutional or nonprofit path. A dentist-owned group may use shared services without outside capital at all. See DSO laws by state and Who can own a dental practice.

​

Start with the ownership path

Before forecasting earnings, make the legal and economic perimeter explicit: The management agreement should implement that lawful perimeter. It should not be used to recreate prohibited equity ownership through contract rights, fees, account control, or an exit the practice cannot exercise.

​

Keep three economic views

Operators, counsel, investors, and accountants need three views that reconcile but answer different questions.

​

1. Dental-practice standalone

The practice view starts with patient and payer revenue recognized by the billing or contracting entity. It includes the practice’s own clinical and operating costs, taxes, liabilities, and management-fee expense. Its ending income and cash belong to the practice and are available only for uses and distributions permitted by its governing documents, state law, contracts, and solvency. This view answers:

• Does the location or practice produce sustainable earnings before and after the management fee?
• Can it fund active treatment, patient credits, refunds, payer recoupments, payroll, taxes, laboratory obligations, rent, insurance, capital needs, and working capital?
• Is the fee actually affordable, invoiced, approved, and paid under the agreement?
• Who lawfully owns any residual and who may authorize its use?

There is no general rule that the practice must end each month near zero. A deliberately thin residual can create patient-continuity, creditor, tax, governance, and regulatory risk if it leaves the practice unable to meet its obligations.

​

2. DSO standalone

The DSO view records management and other support revenue it is legally entitled to earn, less the cost of delivering those services and its corporate expenses. It may include support personnel, technology, billing infrastructure, procurement, real estate, equipment, insurance, debt service, and taxes when the selected state structure and contracts place those items in the DSO. This view answers:

• What services generate the fee, and what do they actually cost to deliver?
• Which costs are directly attributable, which are shared, and which do not belong in the fee base?
• What is the DSO’s gross margin by practice and service line?
• How much fee revenue is billed, collected, disputed, deferred, or uncollectible?
• How concentrated and terminable are the DSO’s contracts?

DSO standalone EBITDA can be important to an investor that owns the DSO. It is not a substitute for testing whether the underlying fees are lawful, supportable, collectible, and durable.

​

3. Consolidated or combined reporting

If the applicable accounting framework requires consolidation, the practice’s management-fee expense and the DSO’s corresponding fee revenue eliminate. The fee changes the standalone location of earnings and cash; it does not create external revenue or earnings for the consolidated group. An illustrative pre-tax example: The $220 fee allocates standalone earnings between the entities. After elimination, the combined operating income remains$120. Taxes, debt, minority interests, distributions, and nonconsolidated ownership can change what each stakeholder receives, but double-counting fee revenue never creates enterprise value. Do not label a combined schedule “consolidated” merely because management wants to see both entities together. The consolidation conclusion depends on the applicable accounting framework and the actual power and economic-interest facts. Keep a clearly labeled management-combined view if that is all the facts support.

​

What the management fee is pricing

A support fee should be reproducible from the written agreement and the operating evidence. The file should show:

1. Authorized services and assets. What the DSO actually supplies, and whether the state permits that allocation.
2. Delivery evidence. Personnel, vendor contracts, system access, service levels, work queues, invoices, and other proof that the services occurred.
3. Calculation. The fee base, allocation keys, markup or unit rate, exclusions, timing, true-ups, and treatment of disputed or deferred amounts.
4. Pricing support. Cost data, comparable arrangements, and fair-market-value or commercial-reasonableness work where relevant. FMV evidence does not override an express formula, control, ownership, or referral prohibition.
5. Payment behavior. Invoices, approvals, cash transfers, intercompany balances, waivers, deferrals, and amendments should match the contract.
6. Practice capacity. The practice must remain able to satisfy its existing and reasonably foreseeable obligations.

A fee can be too high even when its arithmetic is correct. It can also be too low to support the promised services. Neither result should be repaired by retroactively changing the formula to reach a desired EBITDA number.

​

Compare formulas without assuming a winner

The formula is a drafting and operating choice made after the state analysis, not a maturity stage every group passes through. Fixed and cost-plus formulas can reduce direct revenue-dependency risk in some jurisdictions, but neither is a national safe harbor. A percentage formula may be allowed under one state’s text and prohibited, restricted, or outside a statutory support pathway under another. The same is true of “shared savings,” performance fees, per-patient charges, and prior-period resets.

​

Five dental-specific state signals

These provisions illustrate why a national formula chart is unsafe. Read the complete text, definitions, exceptions, and remedies on Fee-splitting rules. Those provisions do different legal work. Nevada defines a condition of an exclusion, New Jersey and New York regulate fee splitting, North Carolina regulates management arrangements, and Maryland defines a permitted support-services pathway. Do not collapse them into “five states ban percentages.” For every formula, separately check:

• Dental fee-splitting and corporate-practice rules
• Referral-linked compensation and, where federal program business is involved, applicable fraud-and-abuse law
• Professional-entity, DSO-registration, asset, account-control, and clinical-independence rules
• Payer contracts, enrollment representations, refund duties, and recoupment rights
• Federal, state, and local income, sales, use, gross-receipts, payroll, and related-party tax treatment as applicable
• FMV, commercial-reasonableness, fiduciary, solvency, fraudulent-transfer, and distribution restrictions where applicable

​

Preserve the practice’s ability to operate

“Fee coverage” is more than whether cash happens to be in the bank on invoice day. Build a rolling practice-level cash forecast that reserves for obligations such as:

• Clinical payroll, benefits, payroll taxes, and required supervision
• Patient deposits, credit balances, refunds, and unearned membership-plan benefits
• Active orthodontic, aligner, implant, prosthetic, laboratory, remake, and warranty obligations
• Payer overpayments, audits, recoupments, appeals, and claims runout
• Rent, licensed software, dental supplies, equipment service, insurance, and taxes
• Malpractice matters, records access and retention, closure duties, and transition costs
• Capital expenditure and working-capital needs necessary to continue patient care

The exact legal priority among these items is state-, contract-, and fact-specific. The operating control is to identify them before authorizing the fee, a distribution, or an intercompany transfer. A contractual deferral provision can manage timing; it does not make an excessive fee lawful or turn an insolvent practice into a healthy one. Track at least three fee-coverage measures by practice: Persistent nonpayment, automatic waivers, unexplained accruals, negative equity, or repeated undocumented support-company advances warrant investigation. They can indicate an unaffordable price, unsupported service scope, broken unit economics, inadequate capitalization, or documents that do not match operations. See Intercompany money movement.

​

How investors can underwrite the structure

An investor can underwrite economics without assuming it owns the dental practice by contract. The investment case should identify the legal source of each cash flow and right:

​

DSO standalone underwriting

• Fee revenue by executed agreement, state rider, practice, and service line
• Cost to serve, allocation method, and gross margin by customer
• Invoice-to-cash conversion, aging, waivers, disputes, and related-party balances
• Contract term, termination, transition, assignment, change-of-control, and enforceability risk
• Customer and owner concentration, including succession risk
• Technology, procurement, real-estate, equipment, and workforce economics the DSO may lawfully hold
• DSO debt, taxes, capital expenditure, and working-capital needs

​

Practice standalone underwriting

• Collections after contractual adjustments, refunds, and recoupments
• Clinical compensation, laboratory and supply costs, occupancy, and other direct expenses
• Management-fee coverage and post-fee liquidity
• Active-treatment and patient-credit liabilities
• Payer, provider, location, and credentialing dependencies
• The ownership and distribution rights that actually exist under the state path

​

Consolidated or transaction underwriting

• Eliminate intercompany fees and balances exactly once
• Separate accounting consolidation from a non-GAAP combined or transaction pro forma
• Bridge from combined operating performance to the cash flow and equity interests the investor is legally acquiring
• Show noncontrolling interests, practice interests not acquired, debt, taxes, earnouts, rollover rights, and required capital separately
• Stress-test clinician retention, payer changes, integration costs, de novo ramp, fee enforceability, and termination as well as the entry and exit multiple

A platform valuation premium is an underwriting hypothesis, not an automatic reward for aggregating practices. Integration quality, same-store performance, clinician retention, payer economics, leverage, contract durability, market conditions, and the exact equity acquired determine whether any premium exists. Do not “solve” a valuation gap by increasing management fees beyond the services and law that support them.

​

What OCA and Packard establish, and their limits

In In re OCA, the Fifth Circuit applied Texas law to the agreements before it and evaluated their interlocking fee, term, account-control, asset, and operational provisions. It held those agreements void because the complete arrangement transferred too much control; it did not announce that every percentage, fixed, or cost-plus dental fee is lawful or unlawful nationwide.⁶ Packard addressed later recovery claims arising from that failed arrangement. Its restitution result depended on the governing law, pleadings, and posture of that litigation. The case shows that an unlawful agreement can destroy expected contract value and complicate recovery. It does not establish that every disputed DSO fee forfeits all invested capital.⁷ Underwriting should cover owner eligibility, actual authority, fees, services, accounts, assets, term, exit rights, succession, and day-to-day conduct. Favorable service economics do not resolve impermissible control, and clinical-reservation language does not resolve a contradictory fee or cash practice.

Monthly operator control sheet

Close each period with a package that can answer both the financial and legal diligence questions:

1. Practice-standalone P&L, balance sheet, cash flow, and obligation forecast
2. DSO-standalone P&L, balance sheet, cash flow, and cost-to-serve schedule
3. Consolidating or combined schedule with every intercompany elimination visible
4. Fee calculation by practice, including the agreement version and state rider used
5. Invoice, approval, payment evidence, deferral, waiver, and aging detail
6. Cost-allocation workpapers and supporting vendor and payroll records
7. Evidence that material contracted services were actually delivered
8. Patient-credit, active-treatment, refund, recoupment, tax, and liquidity reserves
9. Ownership, distribution, debt, and noncontrolling-interest bridge
10. Exceptions log for formula changes, true-ups, disputes, law changes, payer changes, and document-operation mismatches

That package lets management see whether the services make money, whether each practice can safely pay for them, what eliminates in consolidated reporting, and what cash flow the investor actually owns.
