From Scribbled Quotes to Winning £3,000 Jobs

28 February 2026

Dave's been a plumber for fourteen years. Gas Safe registered, time-served, the kind of bloke who can diagnose a boiler fault by the sound it makes. His work is excellent. His quotes were not.

For most of his career, Dave quoted jobs the same way every tradesperson he knew did. He'd look at the job, do the sums in his head on the drive home, and send a text. Sometimes he'd scribble numbers on the back of a receipt and take a photo. Sometimes he'd type it out in the van while eating a Greggs sausage roll. It worked well enough for small jobs. Tap replacements, radiator swaps, the odd boiler service.

Then he started quoting for bigger work. Bathroom refits. Full central heating installations. Jobs worth two, three, four thousand pounds. And something changed.

The job that made him think

Last autumn, Dave quoted for a bathroom refit in a nice semi in Sevenoaks. He went round, measured up, talked through everything with the homeowner. They got on well. He sent over his quote that evening: a WhatsApp message with the job description, a price of £2,800, and a note saying he could start in two weeks.

He didn't hear back for three days. Then a polite message: "Thanks Dave, we've decided to go with someone else."

Fair enough. Happens all the time. But it nagged at him, so he asked. Turns out the other plumber had quoted £3,100. Three hundred quid more than Dave. But they'd sent a proper PDF with their company logo, a full breakdown, warranty terms, and a timeline. The homeowner's exact words were: "It just felt more professional. We felt more confident."

Dave lost a job to someone charging more because his quote looked like an afterthought.

Why bigger jobs need better quotes

When someone's spending £200 on a dripping tap, they don't care much about presentation. They just want it fixed. But when the number gets into the thousands, the psychology shifts completely.

Spending £3,000 is scary for most people. They're looking for reasons to trust you. They want reassurance that you're organised, that you've thought things through, that you won't disappear halfway through the job. Your quote is the only evidence they have before committing.

A text message doesn't give them that reassurance. A proper document does.

Think about it from their side. If you were paying someone three grand, would you feel better about a text saying "bathroom refit 3k" or a document that breaks down every part of the job? You know the answer because you're a customer too, just in different situations.

What Dave changed

Dave didn't buy expensive software. He didn't spend his evenings learning Excel. He started sending proper PDF quotes using NippyAgent, describing the job by voice note and getting a formatted document back straight away. But the tool isn't really the point of the story. What matters is what changed in his results.

He started including these things in every quote:

1. A clear job description. Not just "bathroom refit" but a proper scope. Strip out existing suite, plumb in new bath, basin and toilet, install thermostatic shower, retile wet areas, and so on. The customer can see exactly what they're paying for.
2. An itemised breakdown. Labour on one line, materials on another. Not to the penny, but enough so the customer isn't looking at one big scary number.
3. A timeline. "Estimated 5 working days, starting on or around [date]." This alone makes customers feel like you're organised and serious.
4. Payment terms. 30% deposit, balance on completion. Written down, not assumed.
5. His details. Business name, Gas Safe number, phone number. All on the document. Not hidden in a text thread they have to scroll back through.

The results

In the three months since Dave made the switch, he's won four jobs over £2,500 each. His conversion rate on bigger quotes went from roughly one in five to nearly one in three. He reckons that's an extra £8,000 to £10,000 in revenue, just from presenting the same work differently.

He didn't change his prices. He didn't learn new skills. He didn't start marketing himself on social media. He just stopped sending quotes that looked like they were typed in a rush.

The other thing he noticed: fewer ghosts. People who used to go silent after getting a quote now actually respond. Even the ones who say no tend to reply rather than just vanishing. That matters because a polite "no" today can become a "yes" six months later when they're ready.

The lesson for every tradesperson

This isn't really about Dave. It's about you. You're probably good at what you do. You probably price fairly. But if your quotes look like they took thirty seconds to write, customers will assume the job will get the same level of care.

You don't need to spend hours on each quote. You don't need design skills. You just need your quotes to look like they came from someone who runs a proper business. Because you do run a proper business. Your quotes should show it.

The gap between getting the job and losing it is often smaller than you think. Sometimes it's just a PDF.
