The prompt · ChatGPT

Help me set up invoices that get paid on time.

My business: [what you do]
How I invoice now: [e.g. Word document, notebook]
Payment terms I'd like: [e.g. 14 days, or on completion]
How customers can pay: [bank transfer, card link]
VAT registered: [yes or no]
What slows payment down: [e.g. no reference, people forget]

First ask me up to 4 short questions. Wait for my answers.

Then:
1. An invoice layout from top to bottom, with what goes where.
2. Exact wording for terms, the due date and how to pay, in plain English.
3. A short covering message for the email or text.
4. A set-up checklist for an invoicing app: business details, numbering, terms, reminders.
5. What GOV.UK says an invoice must include, with the link to check.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English.

For what GOV.UK says an invoice must include, use web search and name the page you used. If it doesn't search on its own, open View all tools and choose Search.

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. what you do: a short note you already have. e.g. Word document, notebook: a short note you already have. Leave the rest of the prompt as written.

This does not give tax advice. The books stay in the accounting system.
