The “Until” Guarantee
Most guarantees tell a buyer that if things go wrong, they can get their money back. The “Until” Guarantee goes further. It tells them you will keep working until things go right.
That single shift in framing changes how a buyer feels about the risk of buying from you. A refund means you fix the financial loss. An “Until” Guarantee means they never have to experience the loss at all.
The “Until” Guarantee is a commitment to keep working until the client gets the result they paid for. However long that takes.
What Is The “Until” Guarantee?
Buyers fear two things when they invest in a service. They fear it will not work. And they fear a fixed time limit after which the seller stops caring whether it did. The “Until” Guarantee removes both fears at once.
Because you commit to the outcome rather than a time period, the buyer knows your interests align with theirs. You both want the same thing. When that is clear, trust builds fast and the barrier to buying drops.
There is also a signalling effect. Offering this guarantee tells buyers that you are confident in your work. You would not make an open-ended commitment if you expected to be working forever. That confidence is reassuring before the buyer has seen a single result.
Why Does The “Until” Guarantee Work?
Most buyers have experienced paying for a service that ran out of time before it delivered the result. A fixed contract protects the seller. The “Until” Guarantee protects the buyer. That asymmetry is exactly why it stands out.
It also removes the nagging doubt that sits behind most purchase decisions. When a buyer wonders whether the supplier will still care six months in, an “Until” Guarantee answers that directly. Because the supplier only finishes when the result is achieved, their attention never drifts.
I use this with my own clients. They are with me until they are happy with their Clear Sales Message. In practice, even the most complex clients reach that point within a defined window. So the comfort the guarantee gives far outweighs the small risk of an edge case taking longer.
How Can You Use The “Until” Guarantee?
You need to do the maths before you offer this. Think about the worst-case client. How long might it take to deliver the result in that scenario? What would that cost you? If the number is manageable, the guarantee makes sense. When it is not, you may need to define the result more tightly or add some conditions.
Define the Result Precisely
Once you have run the numbers, frame the guarantee around the specific result the buyer wants. Not a time period, not a number of sessions, but the actual outcome. When the result is specific and clear, the guarantee carries full weight. Vague guarantees create vague expectations and vague disputes.
Check the Outlier Risk
Think about the unlimited access you are effectively offering. What is the worst case? If you have enough experience to know that most clients land within a predictable window, the outlier risk becomes manageable. The attraction to buyers of getting everything they want, however long it takes, usually far outweighs that outside risk.
Build In a Buyer Condition
So build in a condition that the guarantee applies when the buyer does their part. Some see an open-ended commitment as permission to disengage. A condition protects both sides and keeps the arrangement honest. Something simple like “the guarantee applies when you complete the agreed steps” is enough.
When The “Until” Guarantee Works Best
The “Until” Guarantee works best when the outcome is measurable. Ranking on page one of Google. Hitting a revenue target. Completing a clear deliverable. When the buyer can picture the finish line precisely, the guarantee does its best work.
It also works well when the typical timeline to deliver is predictable even if not fixed. A service that usually completes in three months but runs however long it takes sounds very compelling. The buyer gets certainty. You carry a known, manageable risk.
It is also a strong conversion tool in competitive markets. When two suppliers offer similar services, the one who commits to the outcome wins. Because the “Until” Guarantee makes the decision feel lower-risk, it often tips the balance when everything else is equal.
When The “Until” Guarantee Becomes Dangerous
The main risk is offering this without a clear definition of what done looks like. Without that, the guarantee can create a situation where the buyer keeps moving the goalposts. Define the outcome precisely before you make the commitment, not after.
There is also a risk of the guarantee drawing in buyers who plan to stay passive. Some see an open-ended commitment as permission to disengage. So build in a condition that the guarantee applies when the buyer does their part. That keeps the arrangement fair.
Common “Until” Guarantee Mistakes
Framing It Around Effort, Not Outcome
The most common mistake is framing the guarantee around effort rather than outcome. Saying you will work hard for as long as it takes is not a result commitment. It is an effort commitment. Buyers do not care about effort. They care about results. So commit to the finish line, not the journey.
Skipping the Risk Assessment
A second mistake is skipping the risk assessment. Offering an “Until” Guarantee without running the numbers first can create real problems. So know the worst-case cost before you make the promise. The guarantee should feel bold, not reckless.
Leaving the Result Undefined
A guarantee with no clear finish line is a guarantee with no real meaning. If the buyer can define success however they like, you have no way of knowing when you have delivered it. Define the result, agree it upfront, and write it down. That protects both sides and makes the guarantee something you can both point to.
The “Until” Guarantee – An Example
A digital marketing agency offers an “Until You Rank” guarantee for its SEO service. They commit to working until the client’s site reaches page one of Google for their chosen keywords. Based on their track record, most clients get there within four to six months. But framing it as however long it takes means the buyer has no fear of being left behind. The risk shifts to the agency. That shift makes the offer far easier to say yes to. And that is the logic of the “Until” Guarantee.
So commit to the outcome. Back yourself. Let the buyer know they will get what they paid for, however long that takes. When you can genuinely make that promise, it is one of the most powerful things you can say.
