How tradespeople can use AI to write quotes and chase invoices faster

Last updated 7 July 2026

A tradesperson can use AI to turn a voice note into a written quote, chase an unpaid invoice without the awkwardness, and fire off a holding reply to a new enquiry while still on site. An AI assistant (a chat tool at about £20 a month) does the writing from your prices and facts. You make every decision about money and dates, then check and send.

The paperwork is the second job

You priced the job in your head before you left the driveway. What eats the evening is the write-up: the quote, the chase for last month's invoice, the reply to the customer who messaged at lunchtime. It is all writing, in your name, and it has to be right. That is what an assistant is for. It does not set your prices or your diary. It formats the decisions you have already made.

How do you write a quote from the van?

Voice-note the facts the moment you have them: who it is for, the work, the price you decided, materials, when you can start. The assistant turns that ramble into a tidy one-page quote using your rates and terms, laid out the same way every time. You read the figures, correct anything it assumed, and send it from your phone before you have left the street.

The one prerequisite: your prices need to be written down where the assistant can see them (day rate, call-out, common line items, how you handle materials, VAT, deposit terms), not living only in your head. Quoting from memory is where margin quietly goes missing. The full quotes recipe, with the exact prompts, lives in The Time Refund; to see how a recipe is laid out before buying, the email recipe is free to read in full.

How do you chase an invoice without the awkward bit?

Late payment is normal and chasing it is horrible, which is why it gets left. A short, polite, firm sequence fixes most of it: a nudge at seven days, a clearer one at fourteen, a final notice at thirty. Write the three once, in a tone that stays civil, and reuse them. The assistant keeps them friendly enough to protect the relationship and clear enough to get you paid.

The honest limit: the assistant has no idea who has actually paid. You tell it which invoice, which client, how overdue. It never sees your bank, so it cannot chase the wrong person unless you point it there.

You write invoice chase messages for my trade business. Polite but clear, British English, short.
My business: [name, trade]
Client: [name], invoice for [work] of £[amount], due [date], now [X] days late.
History: [e.g. good customer, first time late, or already reminded once]

Write a chase message that is friendly, states the amount and how overdue it is, gives an easy way to pay, and does not grovel or threaten. If a detail is missing, leave a gap for me rather than guessing.

How do you reply to enquiries while you are working?

A new enquiry that waits until evening is a job that might go to whoever answered first. You cannot stop mid-task to write a proper reply, but you can send a good holding message in ten seconds. Have the assistant draft a couple you can reuse: thanks, that sounds doable, I will get you a proper price by tonight, what is the best number for you? It keeps the job warm without pulling you off the ladder.

Where AI still needs you

Every number it writes needs your eyes before it reaches a customer, because it will state a wrong price as confidently as a right one. It does not know your availability, so start dates are yours. And it cannot tell that a job smells like trouble and deserves a higher number or a firmer deposit. Keep quotes boring and one page: if the customer cannot see what they are paying for, it is not finished.
