Guarantees: Why a Bold Promise Outperforms Every Discount

4 min readRoberto Dal Corso · Published 25 Dec 2025

A bold, well-crafted guarantee is one of the most powerful sales tools available to any business. Yet most businesses either have no guarantee, or a weak one that makes no impression on a potential buyer.

Why Strong Guarantees Work

A strong guarantee removes the primary obstacle to purchase — fear of making a bad decision. When a prospect knows they cannot lose, the decision to buy becomes much easier. The more dramatic, specific, and unconditional the guarantee, the more powerfully it addresses purchase hesitation and the more it signals confidence in the product or service.

The Guarantee Myth

Most businesses avoid strong guarantees because they worry about excessive refund requests. Studies consistently show that fewer than 2% of customers ever claim under a guarantee. The increase in sales generated by a bold guarantee almost always exceeds the cost of honouring the small number of claims — provided the product or service is genuinely good.

How to Write a Guarantee That Works

Move beyond 'if you're not happy, we'll refund'. Write a guarantee so specific, so dramatic, and so confident that it signals complete belief in what you deliver. The goal is a guarantee that makes the prospect think: they really must mean this. If you believe in what you sell, your guarantee should show it — loudly.
