Ask any accountant what makes a professional practice sale different from selling a hardware store, and goodwill will come up almost immediately. In an ordinary business sale, goodwill is usually thought of as the value of the business as a going concern beyond its hard assets — its customer relationships, reputation, and momentum. In a professional practice, that same idea gets a lot more complicated, because a meaningful chunk of that goodwill may be tied to a specific person rather than the practice itself.

This distinction — sometimes described as personal goodwill versus practice (or enterprise) goodwill — sits at the centre of most valuation disagreements in dental, medical, legal, and other professional practice sales. Understanding it doesn't tell you what your practice is worth, but it tells you what the real argument in most deals is actually about.

Personal Goodwill vs. Practice Goodwill

The higher the proportion of a practice's goodwill that is genuinely personal to the departing professional, the more a buyer's post-closing outcome depends on things the purchase agreement can influence but not fully guarantee — patient or client retention, a smooth introduction period, and (where enforceable) a non-compete or non-solicitation clause protecting what's being paid for.

What Tends to Drive Value Up or Down

No specific formula or multiple applies here — valuation is genuinely deal- and practice-specific, and any "typical multiple" you hear quoted should be treated with real skepticism. What professional valuators and buyers commonly look at instead includes:

Where Disputes Usually Come From

Dispute sourceWhat it typically looks like
Retention risk after closingBuyer argues fewer patients/clients transitioned than expected; seller argues the buyer didn't manage the transition well
Personal vs. practice goodwill allocationDisagreement over how much of the price reflects the seller personally versus the ongoing business
Non-compete enforceabilityA dispute over whether the restriction the price was partly based on is actually enforceable as written
Post-closing price adjustmentsWhere the deal includes an earn-out or holdback tied to retained patients/clients or revenue, disagreement over how it's measured
Tax characterizationHow the price is allocated between goodwill and other assets or shares can carry separate tax consequences worth confirming with an accountant before signing

Purchase agreements for professional practices commonly try to get ahead of these disputes with a clearly drafted transition period, well-defined non-compete/non-solicitation terms, and (where used) a specific mechanism for resolving any earn-out or holdback calculation disagreements — rather than leaving "we'll work it out" as the plan.

Common Misconceptions

Frequently asked questions

Who typically values goodwill in a practice sale — a lawyer or an accountant?

Valuation itself is generally the work of a qualified business valuator or accountant with relevant experience; a lawyer's role is to translate that value into a properly structured, enforceable purchase agreement — including the non-compete, transition, and any price-adjustment terms that protect what was paid for.

Can I get a specific "going rate" for practices like mine before I negotiate?

Be cautious about relying on any generic multiple or rule of thumb — actual sale prices vary enormously based on the specific practice, its patient/client base, location, and deal terms. A proper valuation of your specific practice is a better starting point than a general benchmark.

Does it matter whether the sale is structured as a share sale or an asset sale?

Yes — beyond the general tax and liability differences between the two structures, how the purchase price is allocated to goodwill versus other assets or shares can carry its own tax consequences, which is worth confirming with your accountant before the structure is finalized.

What can a seller do to make goodwill more "practice" than "personal"?

Building systems, training staff, and diversifying the patient or client base well before a sale are common ways practices increase the durable, transferable portion of their value — though results vary and this isn't something that changes quickly close to a sale.
