How to Write a One-Liner

What a one-liner is

A one-liner is a short statement that names the problem your customer is facing, what you do about it, and how their life is better afterwards.

You will use it more than anything else you write. When somebody asks what you do. At the top of your homepage. In your email signature, on the back of a card, in the first line of a proposal. It is the shortest complete version of your whole message.

I watched one do its job in real time. I was at a business leaders event, three hundred people in the room, and the man beside me spent ten minutes explaining what his company didn’t do. He would start describing a problem in his industry, walk me into it, and then say — but we don’t really do that. He got there in the end: his company installs rubber liners on flat commercial roofs. Ten minutes to arrive at one sentence.

Then he asked what I did.

He leaned in. You could watch it happen. The difference between us was not that my business is more interesting than commercial roofing. It is that I had decided what to say before I got there.

Why yours is hard to write

Because you know your business too well.

You have been inside it for years. Everything about it feels obvious to you, and the things that are genuinely interesting to a customer have become the weather — too familiar to notice. So when someone asks what you do, one of two things comes out.

You list what you sell. “We do commercial roofing, gutters, siding and storm restoration.” True, and it tells the person nothing about whether you can help them.

Or you start with your company. “We’re a family-owned business, been serving the area since 1998…” Also true. Also not what they asked.

Neither is a failure of writing. Both are what happens when you start from the inside of the business and work outwards — which is the natural direction to think, and the wrong direction to write.

The three parts below turn you around. You start from where the customer is standing and work back towards yourself, and by the time you mention your own business the reader already wants to hear about it.

Part one: the problem — always start here

What your customer is struggling with, in their words.

If you take one thing from this page, take this one. Your one-liner has to begin here. Not with your company name, not with what you sell, not with how long you have been doing it.

This is the single most common error I see when a business owner tries to write their own. It comes out as “We’re a roofing company…” or “We’ve been serving the area since 1998…” — and both are true, and both start in the wrong place.

Think about what is happening in the reader’s head. They came with a problem. Until they believe you understand it, nothing else you say is interesting — not your years in business, not your certifications, not your family-owned story. Those things matter later, and they only matter once the person has decided you might be able to help.

Open with their problem and you have answered the only question they are actually asking: does this person get it? Open with yourself and they are still waiting for you to say something about them.

It is also the only one of the three parts that is not about your business, which is exactly why it is the hardest to write and the one people rush.

Write it the way your customer would say it out loud to a friend — not the way your industry says it. A homeowner does not say they require roof remediation. They say the ceiling has a stain on it and it is getting bigger.

The mistake almost everyone makes: describing the practical problem and stopping there. The roof leaks. The books are behind. The phone is not ringing. All accurate, all forgettable — because underneath each one is a feeling, and the feeling is what makes somebody pick up the phone today rather than next spring.

Lying awake when it rains. Dreading the accountant’s email. Watching a competitor get the jobs you used to get. Name that, and the person reading knows you have met someone like them before.

Part two: the solution

What you do about it.

This part is short, and it should be. One thing — the thing that fixes the problem you just named. Not everything you offer.

Listing services here is the most common way a good one-liner goes wrong. The moment you write “roofing, siding, gutters and storm restoration” you have handed the reader a menu and asked them to work out which item applies to them. They will not. Name the one thing that answers the problem, and let the rest of your website carry the range.

It also helps to say it as an action rather than a category. “We handle the whole claim” lands harder than “full-service storm restoration,” because one of those is something you do and the other is something you are.

Part three: the results

How their life is better afterwards.

Not what you deliver. What changes for them.

“We install a new roof” is a deliverable. “You stop checking the ceiling every time it rains” is a result. Same job, and only one of them describes a life the reader recognises as better than the one they have.

The mistake here: stopping at the moment your work ends. Your finish line is the completed job. Theirs is a Tuesday three months later when they have stopped thinking about it altogether. Write that Tuesday.

Watch one get written

Here is the method running from a blank page. The company is invented — Brightside Facilities, a commercial building maintenance firm — so nothing here is anybody’s real copy being taken apart.

The owner’s first attempt at describing the business, before any of this:

Nothing in that is wrong. There is also nobody in it. Now the three parts, one at a time.

Joined up

Read that next to where the owner started. The second one is longer — forty-five words against thirty-eight — and it is far easier to say out loud. Length was never the problem.

And nothing was given up to get there. Every claim in the original survives the rewrite:

Four claims in, four claims out — plus one the first version never made at all, which is the part a customer actually cares about. Simplifying a one-liner does not cost you what it says. It usually adds something.

Five ways to say the same thing

Once the bones are right, the sentence can change shape without changing meaning. When a client hires me they get five versions, because the version you say at a table and the version you put on a homepage are not the same sentence — and neither is the one that has to fit under your name on a conference badge.

Same three parts underneath all of them. Here is my own, five ways.

Three real ones

Finished one-liners from real businesses, with the three parts marked so you can see the shape underneath.

The Business Brokers

Problem: selling a business is hard, and harder alone. Solution: confidentially value, list and market it. Results: the freedom to do whatever comes next.

Two things this one does that most do not. The solution names their actual process in three verbs rather than calling itself full-service. And it ends on a person rather than a transaction — not “so you can sell,” but who you get to be once you have.

peer2peer.group

Problem: stuck and alone. Solution: connects you with people who do exactly what you do. Results: you solve real problems and grow.

This one opens with a question, which is unusual and works here because the problem is a feeling rather than a fault. It also names the competition it is beating — conferences — without ever saying a word against them.

Brightside Facilities (the invented one, for comparison)

Problem: no time, and the wrong contractor makes it worse. Solution: handles repairs with its own vetted trades. Results: fixed fast, and your team is looked after.

Four ways they go wrong

It starts with you. This is the big one, and it is worth repeating: if the first words are your company name, or what you sell, or how long you have been doing it, you have written an introduction rather than a one-liner. Start with their problem. They will care about you a sentence later, once they believe you understand them.

It lists services. A menu is not a message. Name one problem and one answer to it.

It smuggles in credentials. Awards, years in business, “award-winning” anything. Those belong on the page around the one-liner, not inside it. In a sentence this short, every word spent on your credibility is a word not spent on their problem.

It ends at the deliverable. Your work finishing is not the same as their life improving. Go one step past the handover.

The only test that matters

Read it out loud to someone. Not to check whether they are impressed — watch whether they lean in, and whether the next thing they say is a question about their own situation. That is the sound of a one-liner working.

If you stumble reading it, it is too long. If they nod politely, the problem is probably part one.
