Home / Resources / Deferred Revenue in Practice Accounting
The most commonly mis-booked line in practice accounting.
Dental membership plans, veterinary wellness plans, optometry annual supply orders, mental health program enrollments. Different names, one accounting problem: the money arrives before the work does.
What deferred revenue actually is
When a patient pays today for care you'll deliver over the next twelve months, you have their cash but you haven't earned it yet. Accounting treats that correctly as a liability — an obligation to deliver — which converts to revenue gradually as care is provided.
Booked incorrectly, the entire amount lands as revenue in the month of sale. The practice appears to have a spectacular month, then appears to have poor months afterward while delivering the care it already sold. The trend line becomes meaningless.
Why it distorts every decision
An owner looking at inflated revenue in a strong sales month may hire, expand, or take a large distribution. The obligation attached to that cash doesn't appear anywhere they can see it. Then delivery months look weak, and the same owner concludes the practice is declining when nothing has actually changed.
It also distorts valuation. A buyer or lender doing diligence will restate deferred revenue immediately, and a practice whose books never recorded it will see its earnings number revised downward at exactly the wrong moment.
How to know if yours is wrong
Three quick checks. First, look at your balance sheet: is there a deferred revenue or unearned revenue liability at all? For most practices selling packages or memberships, if the answer is no, the books are wrong. Second, look at monthly revenue over the past year — unexplained spikes in months with strong package sales are the signature. Third, ask what happens to an unfinished package if a patient leaves. If nobody can answer, the liability isn't being tracked.
Fixing it
Restating deferred revenue is the most common cleanup we do. It involves identifying every open package and plan, calculating what portion remains undelivered, and establishing the liability with a corresponding adjustment to prior revenue. It takes weeks rather than months, and the first accurate month afterward is usually a surprise — sometimes a good one.
If you sell anything prepaid — memberships, packages, plans, series — check your balance sheet for a deferred revenue liability before you read anything else on this site.
