What is a letter of demand?

A letter of demand is a formal written request for payment of an overdue debt. It states the amount owed, references the relevant invoices, sets a deadline for payment, and outlines the consequences of non-payment. It is usually the step that prompts payment before any recovery or legal action.

Is a letter of demand legally binding?

A letter of demand is not a court document and does not by itself compel payment. It is, however, important evidence that you formally requested payment and gave the debtor an opportunity to pay before escalation. It is not legal advice — for disputed debts seek advice tailored to your situation.

How long should I give the debtor to pay?

Seven to fourteen days is common for a commercial account. The period should be reasonable but firm. A final notice before action may use a shorter window where earlier requests have been ignored.

What happens if the letter of demand is ignored?

If the deadline passes without payment or contact, the usual next step is to refer the account to a commercial recovery agent such as Merion, who can pursue it on a commission-only basis, or to obtain legal advice about formal proceedings.

30 July 2026

[Debtor business name]

Dear Sir/Madam

RE: OVERDUE ACCOUNT — [invoice number(s)]
AMOUNT OUTSTANDING: $5,000.00

We write on behalf of [Your business name] regarding the above account, which remains unpaid and overdue.

Our records show that the amount of $5,000.00 fell due for payment on [original due date] and remains outstanding. Despite the due date having passed, payment has not been received.

We now formally demand payment of $5,000.00 in full.

If payment of $5,000.00 is not received in full by 13 August 2026, we may refer this matter to a commercial recovery agent and/or commence recovery action. Costs and interest may be added to the amount claimed.

If you believe this amount is incorrect, or you are unable to pay in full, please contact us immediately to discuss the matter — we would prefer to resolve this with you directly.

Please disregard this letter if payment has already been sent.

Yours faithfully

[Your business name]
