Update an old quote when your costs have gone up

A customer comes back months later ready to go ahead on an old quote, but materials and your rates have risen since. Get a reply that updates the price without losing the job.

The prompt · ChatGPT

A customer wants to go ahead on an old quote. Help me update it.

The job and old quote: [details and date]
What the quote said about validity: [e.g. 30 days, or nothing]
What's changed: [e.g. timber up, my day rate up]
My new price: [amount]
How much I want the job: [details]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A short, friendly reply that's glad they're back and explains the change in one or two lines.
2. The updated quote wording with a clear validity date.
3. Ways to soften it if I want to (phase the work, swap a material, hold the old price for part of it).
4. A validity line for all my future quotes.

Use only what I've given you, leave blanks for any price or fact I haven't given, and don't invent anything. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.

A short example

Fill the blanks, then paste. details and date: a short note you already have. e.g. 30 days, or nothing: a short note you already have. Leave the rest of the prompt as written.
