Perfecting a Debt Collection Letter

When an invoice is overdue, the way you communicate can make all the difference. A well-crafted debt collection letter can prompt payment quickly without damaging your business relationship. But how do you strike the balance between firm and fair?

What Is a Debt Collection Letter?

A debt collection letter also called a letter of demand is a written notice that formally reminds a customer of their unpaid invoice and requests immediate payment. It’s often the last step before outsourcing to a debt collection agency or pursuing legal action.

In New Zealand, these letters must follow specific standards to be compliant and ethical.

When Should You Send a Collection Letter?

If you’ve already:
? Sent a reminder
? Attempted follow-up calls/texts/emails
? Offered a payment plan
...and still haven’t received payment after 30–60 days, a collection letter is your next move.

What to Include in a Debt Collection Letter

Your collection letter should be clear, professional, and leave no room for misinterpretation. Include the following:

- Business Details
- Name, company, and contact info at the top.

- Debtor’s Information
- Full legal name or business name and their contact details.

- Invoice Details
- Reference the invoice number, amount owed, due date, and any relevant contract terms.

- Clear Request for Payment
- Politely, but firmly, request immediate payment and specify a deadline (e.g., “within 7 days”).

- Consequences of Non?Payment
- Mention possible escalation, such as involving a debt collection agency or legal action.

- Payment Instructions
- Bank account or payment portal details must be easy to find.
