Payment reminder letter template

A polite first reminder is often enough: it restates the invoice number, date and amount, sets a new deadline and says where to pay. The template is already in the tool above; for later reminders you can add default interest and announce debt collection.

Template text

This is the text already in the letter above. You can also copy it from here.

Payment reminder: invoice no. [number] of [date]

Dear Sir or Madam,

According to our records, invoice no. [number] of [date] for CHF [amount], due on [due date], has not yet been paid. Please transfer the amount by [date, for example within 10 days] to account IBAN [IBAN], quoting the invoice number. A copy of the invoice is enclosed. If you have made the payment in the meantime, please disregard this letter. We are happy to answer any questions.

Kind regards

Before you send it

  • With a fixed due date the customer is in default from the next day (art. 102(2) CO); from default, 5 % interest a year is due (art. 104 CO).
  • Reminder fees only if agreed.
  • Enclose a copy of the invoice with the QR payment part: amount and reference need not be retyped.

Frequently asked questions

When is the customer in default? +

If the invoice has a fixed due date, from the following day without a reminder (art. 102(2) CO). Without a fixed due date, default starts with the reminder.

Can I charge default interest? +

Yes: from default, 5 % a year unless the contract says otherwise (art. 104 CO).

Can I add reminder fees? +

Only if they were agreed, for example in general terms the customer accepted.

How many reminders before debt collection? +

The law sets no number. Usually one or two reminders, the last by registered mail with a final deadline, then a debt collection request at the debt collection office.
