Five quoting mistakes that cost tradesmen jobs

1. The slow quote

This is the big one. The customer is keenest the moment you are standing in their kitchen nodding at the job. Every day you take to "send it over" cools that interest and gives a competitor room to get in first. Quotes sent within a day win far more often than quotes sent within a week — not because they are cheaper, but because they arrive while the customer still cares.

Fix: quote on site, before you leave. If that feels impossible, it is because your process is slow, not because on-site quoting is unrealistic. A rate library and a mobile tool turn it into a 60-second job.

2. The vague scope

A quote that just says "bathroom refurb — £4,200" invites trouble. The customer does not know what they are getting, so they assume the most, and you are on the hook for it. Then the extras feel like you are squeezing them, and the job sours.

Fix: itemise. List the work line by line so the price is obviously made of real things, and so anything *not* included is visible by its absence. A clear scope protects your margin and builds trust at the same time.

3. Forgetting the boring numbers

Materials markup. Overhead. The right VAT treatment. The unglamorous parts of a price are exactly the parts a rushed quote drops — and every one you forget comes straight out of your own pocket. Forget the VAT treatment on a reverse-charge job and you are reissuing invoices instead of getting paid.

Fix: never build a price from memory. Defaults for markup and overhead, automatic VAT per line, nothing left to a tired Friday brain. (More on the tax side in construction VAT reverse charge, explained.)

4. No signature, no commitment

A verbal "yeah, go on then" is not a yes you can hold anyone to. Without a record of acceptance, scope creep is one conversation away and you have nothing to point back to. It also makes the eventual invoice feel like it came from nowhere.

Fix: capture acceptance the moment you get it. A signature on the phone screen at the kerbside, a tap that turns the accepted quote into a numbered invoice — the agreement is recorded while everyone is still smiling.

5. No follow-up

Plenty of quotes do not get a yes or a no — they just go quiet. The tradesman who assumes silence means no walks away from work that was one nudge from closing. People get busy; a polite follow-up two or three days later closes jobs that would otherwise have evaporated.

Fix: keep a simple list of quotes out and their status, and chase the open ones. It does not need to be a CRM with a thousand features — just a record of who you quoted, for what, and whether you have heard back.

Fast, itemised, complete, signed, followed up. Get those five right and you will win jobs off tradesmen who are better with the tools than you are.

Notice that none of the five is "be cheaper." Price is rarely the real reason a quote loses. Speed, clarity and follow-through win far more work than shaving your margin ever will — and unlike a discount, they cost you nothing.
