How to Write a Money-Back Guarantee for Your Online Business

How do you write a money-back guarantee?

You write a money-back guarantee in three lines. The first names the result the customer should get, in the customer's words. The second sets the window, a specific number of days from purchase, in which they can ask for their money back. The third says exactly how they claim it: where to write, what to include, and how quickly the refund is sent. Then you choose the type that fits the offer. A small product or a first month of a membership gets an unconditional guarantee, a course or program where the customer has to do the work gets a conditional one, and an ongoing subscription usually gets no refund but a cancel-anytime promise instead. Keep it short, put it next to the price, and honor it without argument.

In client work the guarantee is usually the last thing written and the first thing a buyer reads. I have seen a sales page for a well-built program end with "satisfaction guaranteed" and nothing else, and the questions that came in were all the same: guaranteed how, for how long, and what do I have to do? The owner had written it to sound reassuring. It read as evasive. We replaced it with three plain lines and the questions stopped, because the buyer could now see the risk they were taking, and it was small.

What a money-back guarantee is for

A money-back guarantee has one job: to remove the risk of the first purchase. A buyer who has never bought from you is weighing a real price against a promised result they cannot verify. The guarantee shifts the risk from them to you, which is the correct place for it, because you know whether the offer works and they do not. It is a component of the offer, alongside the price and the promise, and [how to create an irresistible offer](/blog/how-to-create-an-irresistible-offer) is where it belongs in the larger design. It is not a legal document, and writing it like one defeats the purpose.

It is also not a substitute for a clear offer. A guarantee on a vague promise is a vague guarantee. If the customer cannot tell what result they were supposed to get, they cannot tell whether they got it, and neither can you. Write the promise first, then guarantee the promise. And it is not there to protect you from disputes. A card holder can dispute a charge through their bank regardless of what your policy says. A clear, fast guarantee reduces disputes because customers write to you instead of to their bank. A vague or grudging one produces exactly the disputes it was meant to prevent.

The Three-Line Guarantee: Result, Window, Claim

The Three-Line Guarantee is the shape I use with every client who sells something online. Three lines, each answering one question the buyer is asking.

Read the three lines together and they should sound like a person, not a policy. "If you build it and it does not work, email me and I will refund you" is a guarantee. "Refunds are considered on a case-by-case basis subject to the terms herein" is a warning that refunds are not going to happen. The buyer can tell the difference in one reading, and so can the mailbox provider that decides whether your next email is spam.

Which type of guarantee to use

There are three shapes that cover almost every online offer, and the offer decides which one fits.

The mistake I see most is choosing the type by fear rather than by fit. An owner who worries about refunds puts a conditional guarantee with six conditions on a $27 template, and the conditions cost more sales than the refunds ever would. Match the guarantee to what the customer has to do to get the result. If they only have to read it, guarantee it unconditionally. If they have to build something, guarantee the build.

How to write the guarantee copy

• Put it next to the price, on the sales page and on the checkout. A guarantee the buyer has to search for is not doing its job at the moment of decision.
• Write it in the first person. "I will refund you" carries more weight than "refunds will be issued." A named person is standing behind it.
• Use a number of days, not a phrase. "Thirty days" is a guarantee. "A reasonable period" is an argument waiting to happen.
• Name the result the way the customer would. If the promise on the sales page is a working funnel, the guarantee says a working funnel.
• State the claim step in one sentence, with a real email address. The customer should be able to picture doing it.
• Say how fast the refund is sent. Five business days, or whatever your payment processor actually takes. Then meet it.
• Give it a name if it helps the offer. "The Working Funnel Guarantee" is easier to remember and repeat than a paragraph, and it ties the guarantee to the result.
• Keep the legal terms separate. A refund policy page can hold the full terms. The guarantee on the sales page is the promise, in plain words.

How to handle refund requests

Honor the guarantee exactly as written, quickly, and without a fight. A customer asking for a refund inside the window is doing what you told them they could do. Refund the same day if you can, confirm it in one short email, and ask one question: what were you hoping for that you did not get? Most people answer, and the answers are the most honest feedback the offer will ever receive. Do not argue, do not offer a discount to stay, and do not make them justify it beyond the condition you set. A refund handled well is often the reason someone buys the next thing.

Track two things: how many refunds you issue and why. If the number is low, the guarantee is working and the offer is sound. If it climbs, read the reasons before changing the guarantee, because the cause is usually the promise, the delivery, or the wrong buyer, not the refund policy. The same reasons feed [how to reduce customer churn](/blog/how-to-reduce-customer-churn-with-ai) for a membership.

Money-back guarantee mistakes

• "Satisfaction guaranteed" with nothing else. It names no result, no window, and no claim, so it reassures nobody.
• Conditions that read as a trap. If the customer has to submit every assignment, attend every call, and write an essay to qualify, the guarantee is a way of saying no.
• A window too short to use the product. A course that takes six weeks with a seven-day guarantee is asking the customer to decide before they have seen it.
• Hiding the guarantee in the terms page. It belongs beside the price.
• Arguing with a claim. Every argument costs more in trust and in disputes than the refund would.
• Offering a guarantee you would not honor. If the thought of refunding a particular buyer makes you angry, the guarantee is wrong, the offer is wrong, or the buyer was the wrong customer. Fix that, not the policy.
• No guarantee at all on a first purchase. Without one, the buyer carries all the risk, and the price has to be lower to compensate.

Where the guarantee sits in the offer

The guarantee is strongest on the first rung of [the value ladder](/blog/how-to-build-a-value-ladder), where the customer knows you least, and it can loosen as trust grows. An Entry offer gets the most generous guarantee you can afford, because its whole job is to make the first purchase easy. The Core offer gets a conditional guarantee tied to the work. The Depth offer, sold to people who have already bought twice, often needs no guarantee at all, because the trust has been earned. And when you raise prices, revisit the guarantee at the same time; [how to raise your prices without losing customers](/blog/how-to-raise-your-prices-without-losing-customers) covers using a stronger guarantee to carry a higher price.

If you sell from a live session, say the guarantee out loud during the offer, in the same three lines. [How to run a webinar that sells](/blog/how-to-run-a-webinar-that-sells) covers where it fits in the pitch. And when the guarantee is set, pricing is the next decision it affects, because a strong guarantee lets a price sit higher than the offer could otherwise carry.
