Demand Letter for an Unpaid Invoice: Email Templates for Freelancers
A demand letter is a formal, written request for payment that states exactly what is owed, why, and what you will do if it is not paid by a set date. For a freelancer it is usually the step after reminders have failed and before collections or small claims court. Many courts expect you to have sent one. It works because it is calm, specific, and leaves the client no room to say they did not know.
What a demand letter must include
- Who owes whom: your name or business and the client company.
- What the money is for: project, dates, invoice numbers, and the agreement or approval.
- The exact amount owed, plus any late fee only if your contract allows it.
- A firm deadline (often 7 to 14 days) and how to pay.
- The next step if unpaid: collections agency, small claims court, or a lawyer. Only name steps you will actually take.
How to send it
- Send by email and keep a copy. For larger amounts, also send a printed copy by certified mail.
- Attach the invoice, the contract or written approval, and your earlier reminders.
- Keep the tone factual. No insults, threats beyond lawful next steps, or public posting.
- Rules differ by state and country. For large or disputed amounts, have a lawyer review it.
