ChatGPT prompts for tradespeople quotes: 20 to copy and use today

The short version: ChatGPT can turn a rough set of job notes into a clear, professional quote in under a minute, as long as you feed it the job details, the materials, the labour hours and your day rate first. Below are 20 prompts you can copy, paste and adjust with your own numbers, covering first quotes, itemised breakdowns, chasers, invoices and price pushback, plus the mistakes that make an AI written quote look thrown together.

Why tradespeople are turning to ChatGPT for quotes

Writing a quote after a long day on site is the job most tradespeople put off. A plumber, electrician, builder or gardener who is good with a wrench is not always fast with a laptop, and a scrappy text message quote loses jobs to a competitor who sends something that looks like it came from a real business. ChatGPT will not price the job for you (it does not know your local material costs or your margin) but it will take the numbers you already have in your head and turn them into a clean, structured document in the time it takes to boil a kettle. That matters most for small trades businesses where one person is the estimator, the fitter and the accounts department.

What to feed ChatGPT before you ask for anything

The output only ever matches what you put in. Before you open a prompt, have these five things ready:

• The customer's name and the job address or postcode
• A one line description of the job (for example: "replace a leaking stopcock and fit two new radiator valves")
• A rough materials list with unit costs, even if it is a guess
• Your day rate or hourly rate, and how many hours or days you expect the job to take
• Any extras: call out fee, VAT status, how long the quote is valid for

Paste all of that into the prompt itself rather than answering follow up questions one at a time. ChatGPT works far better with one dense prompt than a back and forth chat.

Prompts for a first quote to a new customer

1. "Write a plumbing quote for [customer name] at [address]. Job: [job description]. Materials: [list with costs]. Labour: [hours] at [rate] per hour. Call out fee: [amount]. VAT: [registered/not registered]. Quote valid for 14 days. Use a friendly, professional tone, no jargon, and lay it out with clear headings."
2. "Turn these rough notes into a proper electrical quote: [paste notes]. Add a short opening line thanking them for the enquiry and a closing line inviting questions."
3. "Write a quote for a garden landscaping job. Scope: [scope]. Materials: [list]. Labour: [days] at [day rate]. Include a note that prices may change if the ground condition is different once we start digging."
4. "I am a builder. Write a quote for a bathroom refit covering: [items]. Split labour and materials into two clear sections and add a total at the bottom in bold."
5. "Write a short covering message to go with this quote, for a customer who found me through a Facebook recommendation, thanking them and confirming I can start [date]."

Prompts for itemised, materials-heavy quotes

6. "Turn this materials list into a line by line itemised quote table with quantity, unit cost and line total: [paste list]. Add subtotal, VAT at 20 percent, and grand total."
7. "Write an itemised quote for a kitchen rewire: consumer unit, [X] sockets, [X] light fittings, testing and certification. Price each line separately and explain in one sentence why testing and certification is a separate line."
8. "I have a supplier price list here: [paste]. Build a materials section for a quote using only the items I need for [job], and mark up each item by 15 percent."
9. "Write two versions of this quote: a basic spec using standard fittings, and a better spec using named upgraded fittings, so the customer can compare price side by side."
10. "Rewrite this quote so the materials and labour are combined into one day rate per room, instead of itemised lines, because the customer asked for a simpler summary."

Prompts for chasing a quote that has gone quiet

11. "Write a short, friendly follow up message for a quote I sent 5 days ago that has had no reply. Keep it under 60 words and do not sound pushy."
12. "Write a second follow up for a quote I sent 2 weeks ago, mentioning that my availability for [month] is filling up, without sounding like a sales tactic."
13. "Write a final chaser for a quote from a month ago, offering to answer any questions and confirming the quoted price is still valid for another 7 days."
14. "Write a message re-sending a quote after the customer said they lost the original email, with a one line summary of the price and scope."

Prompts for turning an accepted quote into an invoice

15. "Turn this accepted quote into an invoice, add today's date, an invoice number [number], and payment terms of 7 days by bank transfer: [paste quote]."
16. "Write an invoice for a completed job that includes a 50 percent deposit already paid, showing the deposit, the balance due, and the total."
17. "Write a short payment reminder for an invoice that is 3 days overdue, polite but clear about the due date."

Prompts for handling "that's too expensive"

18. "A customer said my quote is too expensive compared to another tradesperson. Write a reply that explains what is included in my price (parts, guarantee, insurance, clean up) without criticising the competitor."
19. "Write a reply offering a cheaper alternative spec for a customer who pushed back on price, without dropping my labour rate."
20. "Write a message offering to split a large job into two phases so the customer can spread the cost, keeping the total price the same."

Prompts for special situations

21. "Write a quote for an emergency call out (burst pipe, no heating, power outage) that explains the higher call out rate compared to a booked job, without sounding like a penalty."
22. "Write a quote covering a job with two possible outcomes depending on what we find once the wall is opened up, with a lower price for the simple fix and a higher price for the complex fix."

Mistakes that make a ChatGPT quote look fake

The quotes that get rejected are rarely rejected because a chat tool wrote a first draft of them; they get rejected because they read like nobody local wrote them at all. Watch for these before you hit send:

• Generic tone. A quote that could have been sent to anyone, for any trade, in any town, reads as mass produced. Add your business name, the street or area the job is in, and a specific detail from the site visit.
• Made up numbers. ChatGPT will happily fill in a materials price if you leave a gap in the prompt. Never let it invent a cost you have not checked yourself. Always paste your own figures rather than asking it to estimate them.
• Over-promising. Watch for lines like "guaranteed for life" or "the cheapest around" that get added to sound persuasive. Cut any claim about guarantees, timescales or pricing that you cannot stand behind in writing.
• Wrong VAT treatment. If you are not VAT registered, check every draft for a VAT line that got added by habit, since ChatGPT defaults to including one.
• No clear next step. A quote with no next step (call to confirm, a date to start, how long the price stands) sits in someone's inbox forever. Always end with one plain action for the customer to take.
• Copy and paste bleed through. If you reuse a prompt across jobs, check the draft has not kept a customer's name, address or job detail from the last job you quoted. This happens more than people expect when prompts are reused quickly between calls.

None of these are reasons to stop using the tool. They are a two minute proofread before you send anything with your business name on it, the same proofread you would do on a quote a new office junior had just typed up for you.

Frequently asked questions

Can ChatGPT price a job for me?

No. It has no access to your local material prices, your supplier accounts or your margin, so it cannot set a fair price on its own. What it can do well is take the price and scope you already know and turn it into a clean, well structured document, which is the part that eats time at the end of a working day.

Is it safe to put a customer's name and address into ChatGPT?

Treat it the same way you would treat any online form: avoid pasting full financial details, and if you are unsure about your account's data settings, use a first name and street only rather than a full address and phone number. For most day to day quotes, a first name and job area is enough for the prompt to work.

Will customers know a quote was written with ChatGPT?

Only if it reads like a template. A quote with your real numbers, a specific job detail and your normal way of signing off will read as yours. Always edit the draft rather than sending it exactly as generated, and read it back once as if you were the customer.

What is the fastest way to reuse these prompts every week?

Save your five best prompts in a notes app on your phone with placeholders like [customer name] and [job description], so you can paste, fill the gaps and send in under two minutes between jobs.

Should I use ChatGPT for the whole invoice and accounts process?

Use it for drafting text: quotes, invoices, reminders and replies. For anything involving actual payment tracking, tax records or VAT returns, keep using proper accounting software or a bookkeeper, since a chat tool is not built to keep financial records.
