Demand letter prompt

What most people type

write a demand letter to a client who owes me $3,200 for a website project finished in July and has ignored 3 invoices

It works, but the AI has to guess your invoice numbers and dates, contract or payment terms and deadline date, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.

Write a demand letter from me to a client who owes me $3,200 for a website project I finished in July. They have ignored 3 invoices.

Use a firm, professional tone that keeps the door open to resolving this without escalation. Don't threaten anything I haven't confirmed, and don't state legal claims or deadlines that depend on jurisdiction as fact.

Include:
- Date, sender and recipient details, and a subject line referencing the project and amount owed
- A short factual summary: the project, the July completion, the $3,200 balance, and the 3 unanswered invoices [invoice numbers and dates]
- Reference to the agreed terms [contract or agreement terms, payment due date, late fee or interest policy, if any]
- A clear demand for full payment by [deadline date], with [accepted payment methods and instructions]
- What happens if payment isn't received by then [next steps I'm willing to take, e.g. collections or legal action], worded cautiously
- An invitation to contact me by [contact details] to discuss a payment arrangement
- A signature block

Keep it to one page, in a format ready to paste into a document or email. After the letter, add a one-line note on sending it with proof of delivery and suggest checking it against local law or with a lawyer before sending.

Replace the [brackets] with your details before you send it: invoice numbers and dates, deadline date, accepted payment methods and instructions, contact details.

Why this version works

• Listed standard demand letter components. A usable letter needs facts, deadline, payment info, consequences.
• Added placeholders for unknown details. Avoids invented invoice numbers, terms, dates and contacts.
• Set one-page length and delivery note. Fits a demand letter and prevents rambling.
