Most patient acquisition guarantees promise a number of patients and never define what a patient is. That sounds like a technicality until day 90, when the agency says it delivered and the clinic says it did not, and both are looking at different numbers from different systems, neither of which was ever agreed on.
For telehealth clinics the problem is sharper than for anyone else, because the payment usually happens somewhere the clinic’s own tools cannot see.
The Unit Depends on the Clinic Model
There is no universal definition of a paying patient, which is exactly why it has to be written into the contract rather than assumed.
For an in-person clinic, the workable unit is someone who paid a deposit and booked a consultation. Both halves matter. A booking without money attached is a no-show risk, and a deposit without a scheduled time is not yet a patient.
For an asynchronous telehealth clinic, where the patient completes an intake and pays before speaking to a provider, the unit is a first-time paid order at checkout. This is the cleanest of the three, because the payment event is unambiguous and happens once per new patient.
For a synchronous telehealth clinic, where the consultation happens before any payment, the honest unit is a booked consultation. An agency that promises paying patients on this model is promising something it does not control, because the conversion happens in the provider’s consult, not in the funnel.
Pick the one that matches how money actually moves in your clinic. Then make sure it is the one in the contract, because contract language drafted for an in-person practice gets reused on telehealth accounts constantly, and the mismatch surfaces at the worst possible time.
The Counting Problem Nobody Raises Before Signing
Here is the part that catches telehealth clinics specifically. If your checkout runs on a third-party platform, the order record lives in that platform’s database. Not in your CRM, not in your ad account, not anywhere your agency can reach.
Which means a guarantee denominated in paying patients depends entirely on whether that platform will send the data out. Some platforms offer an order webhook that fires on every new order, which solves the problem completely. Some offer a periodic report, which solves it slowly and manually. And some will not provide either, in which case the number in your contract is unmeasurable by anyone on either side of it.
This is a question with a real answer, and it takes one email to the provider to get it. The mistake is asking in month two.
“Settle the counting method before ads launch, not after. We have watched a guarantee clock run for weeks against a number that no system in the stack could produce. Everybody was acting in good faith and it still turned into a dispute, because the answer was unknowable by then,” says Simon Molay, founder of ScaleClinics.
When the Clock Starts
A guarantee period should begin when the main patient-facing ads go live, not when the contract is signed.
The weeks between signature and launch are real work: account setup, business verification, funnel build, provider integration, tracking, follow-up automation. None of it produces patients. A clock that starts at signature charges the clinic for that period out of its guarantee window, which quietly moves the risk of a slow launch from the agency onto the clinic. Since the agency controls most of the launch timeline, that is backwards.
The clock should also pause whenever ads pause, including for platform restrictions, billing failures, or a clinic-side request. Otherwise a two-week ad account suspension eats two weeks of guaranteed performance that nobody could have delivered.
What Happens If They Miss
The remedy matters as much as the number. A guarantee with no stated consequence is a forecast. The two common structures are a refund and continued work at no additional management fee until the number is hit.
Continued work tends to align incentives better, because the agency stays on the hook for the outcome rather than buying its way out, but only if the clinic is not obliged to keep funding ad spend indefinitely to collect on it. Read that interaction carefully. Ad spend is normally paid by the clinic directly to the platform and is separate from any agency fee, so “we work for free until we hit it” still has a cost attached on your side. Know what that cost is before you sign.
Four Questions to Ask Before You Sign
Ask these in writing, and read the answers as a set. Any one of them can be answered smoothly. All four together are hard to fake.
What exact event counts toward the guarantee. Which system records that event. Who can independently verify the count, and how often you will see it. What happens to the count if the checkout provider or ad platform changes mid-term.
An agency that answers all four before the contract has thought about fulfillment. An agency that deflects to “we will figure out tracking during onboarding” is telling you the guarantee was written by sales and has not been checked against the operation. That is not necessarily bad faith. It is just a promise nobody has verified can be kept.
