What the bot does

  1. Gather the invoice, agreed terms and any emails about the work.
  2. Run the prompt and send the first reminder.
  3. Put the follow-up dates on your calendar.
  4. Update your invoice template for future clients.

What you end up with

A sequence of three reminders (friendly, firm, final) and a clean invoice template for next time.

Copy this prompt 
A client owes me [AMOUNT] for [WORK], invoice [NUMBER] dated [DATE], due [DATE]. Our relationship: [GOOD / NEW / TENSE].
Payment terms we agreed: [TERMS, IF ANY].

1. Write 3 short emails: a friendly reminder, a firm follow-up a week later, and a final notice that states next steps.
2. Keep them professional and factual; include invoice number, amount and how to pay.
3. Suggest clearer payment terms for my future invoices.
4. Give me a simple invoice template with the fields I should always include.
