What is a demand letter, and what goes on one?

A demand letter is a formal, strongly worded notice sent to a client who has failed to pay. It serves as a final warning before legal action and often prompts immediate payment.

Key components

  • Reference — original invoice number and due date.
  • Amount owed — total including any accrued late fees.
  • Final deadline — the date by which payment must be received.
  • Consequences — what happens if payment isn't received (collections, legal action).
Also used when:Client Won't Pay

  4. Generate the letter and send it via email or certified mail.

Why this matters

Late payments destroy freelance cash flow. A formal demand letter escalates the issue professionally, showing the client you know your rights and are prepared to enforce your contract.
