Writing a guarantee or promise page you can keep

A good service guarantee is a short, specific promise you would keep even on your worst week, written so a customer knows exactly what happens if something goes wrong. "If the repair fails within 90 days, we come back and fix it at no charge" is a guarantee. "Complete satisfaction guaranteed" is a slogan that invites arguments. Here is how to decide what to promise, how to word it, and how to avoid the fine print that turns a promise into a complaint.

Start with what you already do

Most small businesses already have an unwritten guarantee. You go back when a repair does not hold. You redo a haircut that came out wrong. You replace a cake that fell apart in the car. Writing it down does not create a new cost; it turns something you already do into a reason to choose you.

Before you write a word, answer these honestly:

What goes wrong most often in your work, and what do you do about it today?
How long after the job do you still feel responsible?
What will you not cover, and why? Customer damage, weather, parts they supplied, a change of mind.
What does it cost you if you have to honor it on a bad month?

Your guarantee is the overlap between what customers worry about and what you can afford to fix every time.

Make it specific: what, how long, what you will do

Vague guarantees sound generous and cause trouble. "Satisfaction guaranteed" leaves the customer to decide what satisfied means. A specific one answers three questions:

What is covered: the workmanship, the parts, the result, the timing.
For how long: 30 days, one year, the life of the roof, until the end of the season.
What you will do: come back, redo it, replace it, refund part or all of the price.

Examples of wording that works, by trade:

Plumber: "If a repair we made leaks again within 90 days, we come back and fix it free, parts and labor."
House cleaner: "Missed a spot? Tell us within 24 hours and we'll come back and clean it at no charge."
Hair salon: "Not happy with your cut or color? Come back within a week and we'll adjust it free."
Roofer: "Our workmanship is covered for 10 years. If a leak comes from our installation, we repair it at no cost. Shingles also carry the manufacturer's warranty."
Bakery: "If your cake isn't what you ordered, call us the same day and we'll make it right."
Landscaper: "Plants we install are covered through the first growing season. If one dies, we replace it once, as long as it was watered as we explained."
Accountant: "If we make an error on your return, we fix it and pay any penalty and interest it caused."

Each one tells the customer exactly what to expect, and tells your staff exactly what to do.

Promises that are not about repairs

A guarantee does not have to be about fixing mistakes. Some of the best ones are about how you work:

"We show up within the two-hour window we give you, or we call before it ends."
"Your quote is the price. If the job needs more, we stop and ask before doing it."
"We clean up every day before we leave."
"We return every call by the end of the next business day."

These cost little and answer the things customers fear most about hiring a stranger: no-shows, surprise bills, mess and silence.

Fine-print traps that cost trust

The fastest way to turn a guarantee into a bad review is to hide the conditions. Avoid:

Exclusions you mention only after something goes wrong. If the guarantee does not cover weather damage, say it on the page.
Hoops to jump through. Requiring the original receipt, a form sent by mail and photos within 48 hours makes the promise feel like a trick.
"Up to" language that means the customer usually gets less than they expected.
Guarantees that need your judgment. "If we determine the work was faulty" leaves the customer at your mercy. Say what will happen instead: "If a leak comes from our work, we fix it."
A promise in big letters with the limits in small gray text. Put the conditions in the same size, right beneath.

Conditions are fine. Hidden conditions are not.

A simple layout for the page

A guarantee does not need a long page. A short section on the services page or the about page often works better than a page of its own. If you do give it a page, keep it to:

The promise in one sentence, as the headline.
What it covers, in a short list.
What it does not cover, in a short list, in the same size text.
How to use it: "Call or email us with your name and the date of the job. We'll schedule a visit within three business days."
Your contact details, as a tappable phone number and an email address.

Repeat the one-sentence promise in a few places where people decide: near the estimate button, on the services page and in your quotes. If you have reviews where customers mention you coming back to fix something, put one near the guarantee; testimonials on your website covers how to show them.

Warranties, laws and your own paperwork

Some trades have rules about written warranties, especially for home improvement and for products sold with a warranty. Federal rules on consumer product warranties are explained on ftc.gov, and many states have their own rules for contractors. If you are writing a long-term warranty, such as on a roof or a remodel, ask your attorney to look over the wording.

Whatever you write on your website should match what is in your contracts and quotes. If the site says one year and the contract says six months, customers will hold you to the site.

When you change or drop a guarantee

If you change your promise, honor the old one for jobs done under it. Keep a dated copy of what the page said. That protects you as much as the customer.

What to do this week

Write down what you already do when a job goes wrong.
Turn it into one sentence: what is covered, for how long, what you will do.
List what is not covered, in plain words.
Check that the wording matches your quotes and contracts.
Put the promise on your services page and near your estimate button.
