How to Use AI to Write Quotes and Proposals for Clients

A potential client asks, “Can you send me a quote?” and suddenly you’re spending your evening trying to describe the job, work out a price and make it all look professional. Send it too slowly and they’ve gone elsewhere; send something vague and you end up arguing about what was included.

AI can help you turn an enquiry into a clear, well-structured quote or proposal in a fraction of the time. It can ask the questions you forgot, describe the scope precisely, present options and draft terms in plain English. You set the prices and make the promises. This guide takes about 30 minutes the first time, then much less once you have a template.

What you’ll need

• The client’s enquiry or notes from your call
• Your prices, rates or a price list, plus typical costs for materials or extras
• Your usual terms: deposit, payment dates, cancellation, how long the quote is valid
• Your business details, logo and any template you already use
• An AI chatbot and about 30 minutes

Step-by-step: write a strong quote or proposal

1. Clarify the job. Paste the enquiry and ask the AI what’s missing: dates, quantities, access, materials, budget, decision-maker (prompt 1). Asking a few smart questions early prevents disputes later.
2. Choose the format. A quote is usually a short, fixed price for a defined job. A proposal is longer and explains your approach, options and value, which suits larger or competitive jobs. Ask the AI which fits.
3. Define the scope precisely. Ask for a list of what’s included and, just as important, what’s not included (prompt 2). “Painting two bedrooms, walls only, two coats, client to move furniture” leaves little room for misunderstanding.
4. Add your prices and options. You set the prices. The AI can lay them out clearly and suggest offering two or three options, such as basic, standard and premium. Options often help clients say yes.
5. Include terms and timings. Deposit, payment schedule, how long the price is valid, what happens if the scope changes and how to accept. Ask for plain-English wording (prompt 3).
6. Write the covering email. Ask for a short, friendly email that summarises the proposal and makes the next step easy (prompt 4).
7. Follow up. If you hear nothing after a few days, send a polite check-in. Ask the AI for a short, non-pushy follow-up.

Copy-paste prompts

1. What do I need to ask?

Here's an enquiry from a potential client for my [TYPE OF BUSINESS]: [PASTE ENQUIRY OR CALL NOTES]
List the information I still need to give an accurate quote (scope, quantities, dates, access, materials, budget, who decides). Then write a short, friendly email asking these questions in a clear numbered list.

2. Draft a proposal

Write a proposal for [CLIENT NAME] for [JOB]. Details: [PASTE NOTES AND ANSWERS]. My prices: [PRICES OR OPTIONS]. Timeline: [DATES].
Structure: a short summary of the client's needs in their words, my recommended approach, scope (included / not included as bullet lists), options with prices in a table, timeline, payment terms, validity of the quote, and how to accept. Use plain, confident UK English. Don't invent prices, guarantees or credentials.

3. Plain-English terms

Write short, plain-English terms for my quotes as a [TYPE OF BUSINESS]: [DEPOSIT %], payment due [WHEN], quote valid for [DAYS], how changes to the scope are priced, cancellation [POLICY], and what the client needs to provide. Keep it under 200 words. Note anything I should check with a solicitor or trade body.

4. Covering email and follow-up

Write a short covering email to send with my proposal to [CLIENT NAME] for [JOB]. Highlight the recommended option, the price and the start date, and make accepting easy. Then write a polite follow-up email to send if I haven't heard back in [NUMBER] days.

Tips and mistakes to avoid

• Never let AI set your prices. It doesn’t know your costs, your market or your time. Use your own rates.
• Be clear about VAT. If you’re VAT-registered, say whether prices include or exclude VAT.
• Spell out exclusions. Most disputes come from things the client assumed were included.
• Don’t promise what you can’t deliver. Avoid guarantees and timelines you can’t control.
• Keep client data safe. You don’t need to paste full addresses or personal details into a chatbot.
• Put an expiry date on quotes. Material and labour costs change.
• Save a template. Once you have a proposal you like, save it and reuse the structure.

FAQ

What’s the difference between a quote and an estimate?

A quote is usually a fixed price for an agreed job. An estimate is an informed guess that may change. Say clearly which you’re giving so clients know what to expect.

How long should a client proposal be?

As short as it can be while being clear. For small jobs, one page is fine. Larger projects may need a few pages explaining approach, options and timeline.

Should I offer options in my quotes?

Often, yes. Two or three clearly different options let clients choose what fits their budget, and many will pick the middle one.
