Everything in a sales method builds on one sentence: what do you promise the customer? That sentence decides which win points you choose, how you run conversations and what goes in your playbook. Yet many organizations do not have it, or have five versions, depending on who you ask. In this article you read how to write a customer promise in one sentence, test it and make it land in your team.
Why a promise in one sentence
A promise that does not fit in one sentence cannot be remembered by a sales rep, and so cannot be said out loud. And what is not said out loud does not exist for the customer. One sentence also forces you to choose: what do you leave out?
A promise is not a slogan. A slogan is for the outside, the promise is for your own team. It says what the customer may expect from you, every time. It does not have to sound nice. It does have to be true.
Write the promise from the customer's point of view
The most common mistake is a sentence about yourself: "We are the specialist in…". A promise is about what the customer gets or no longer has to do. Three openers that help:
- "With us you always know…"
- "We make sure that…"
- "We take … completely off your hands."
Five examples of a customer promise
Fictional examples from different industries, to show the form:
- Installation company. "With us you know where you stand within a day."
- Fall protection. "Everyone who works at height at our customers comes home safe every day."
- Wholesaler. "What you order before four o'clock is on the building site tomorrow morning."
- Business services. "We take your payroll completely off your hands, with no surprises."
- Software company. "Within thirty days your whole team is working with it, or we keep coming by until they are."
How to write the sentence: five steps
You rarely write a good promise in one go. This order helps:
- Collect what customers say. Why did they choose you? Why did they stay? Look in emails, reviews and your sales reps' notes. Write down their words, not yours.
- Find the pattern. Often one thing keeps coming back: speed, certainty, taking work off their hands, expertise. That is your core.
- Write five variants. Use the openers above. Write fast, cut later.
- Pick one and make it shorter. Remove every word that adds nothing. "High-quality" and "optimal" can usually go.
- Let it sit for a week. Then read it aloud. Does it sound like something you would say at the table with a customer? Then you are on the right track.
The test
Hold your sentence against these four questions:
- Checkable. Can a customer check whether you deliver on it?
- Yours. Could the competitor use exactly the same sentence? Then it is too generic.
- Memorable. Can every sales rep recite it from memory after reading it once?
- Directional. Does every win point you choose fit this sentence?
Then test the sentence with three sales reps and three customers. Ask the sales reps to repeat it in their own words. What comes back shows whether it lands.
A fictional example: from four sentences to one
An installation company in commercial construction asks four people what they promise the customer. The managing director says "quality". The sales manager says "personal contact". A project leader says "we think along with you". An account manager says "we are fast".
They put the customer feedback from the past year next to it. What stands out? Customers mostly value knowing quickly where they stand: a price indication, a schedule, an answer about a breakdown. Speed in clarity, not in execution.
The sentence becomes: "With us you know where you stand within a day." After that the choices follow by themselves. One win point becomes the callback within four hours of a request. The exit criterion of the first phase gets a time attached. And in the onboarding program new people first learn how to deliver on that promise.
Common mistakes with a customer promise
- Too much in one sentence. "Fast, reliable and personal" is three promises. Choose one. The other two may exist, but they are not the promise.
- Promising something you do not always deliver. A promise you break now and then costs more trust than no promise. Choose what you can deliver every time.
- The promise only on the website. If sales reps do not know it, it stays marketing. Discuss it in the sales meeting and in the onboarding program.
- Never adjusting it. Markets change. Look at it every year, for instance in the first quarter.
How to make the promise land in your team
A sentence on paper changes nothing yet. What matters is that sales reps use it. That takes repetition, not a single presentation.
- Let the team co-write. People adopt a sentence faster when they have worked on it themselves. Present two or three variants and let the team choose.
- Ask for examples. Have every sales rep tell about a customer situation where you delivered on the promise. And one where it just did not work out.
- Use it in conversations. Let sales reps practice how they bring the promise into a first conversation, in their own words.
- Come back to it. Make the promise the theme of the sales meeting a few times a year. Where do we deliver on it, where not?
If you notice a colleague does not say the promise, first ask why. Sometimes the sentence does not match what they see at customers. That is useful information, not unwillingness.
Worksheet for your first session
Want to start tomorrow? Plan an hour with two or three people who have a lot of customer contact. Bring these questions:
- Why do customers choose us? Write down the literal words you hear from customers.
- What would a customer miss if we were gone tomorrow?
- What do we do that the competitor cannot or will not do?
- Which of these answers can we deliver on every time?
- Write one sentence. Use one of the openers and test it right away against the four questions above.
What the promise does in the other building layers
The promise is the start of the chain. From the promise follow your win points in building layer 3: the moments where the customer notices you mean it. Your exit criteria in building layer 2 become sharper, because you know what you qualify on. And in building layer 6 you translate the promise into behavior: what does a sales rep do and not do? If you serve several industries, you can put a different accent on it per industry. The core stays the same sentence.
Frequently asked questions
What is the difference between a customer promise and a slogan?
A slogan is for the outside world and may play with words. A customer promise is for your team: what may the customer expect from you every time? It has to be checkable.
How do you write a good value proposition for SMBs?
Start with what customers themselves say, find the pattern and write it down in one sentence from the customer's point of view. Then test it with sales reps and customers. Keep it short enough to say out loud.
Can you have a different promise per target group?
Yes, as long as the core stays the same. Per industry you can put a different accent on it, for instance what speed means for a contractor or for a healthcare organization.
How often do you adjust a customer promise?
Look at it deliberately once a year. Change it only if your offering or your customers have really changed. Nobody remembers a promise that changes every quarter.
Capturing
Capture the promise in the Value and promise building block of building layer 1. Because everything builds on it, a later change shows you right away which win points, conversations and documents need another look.
