Payment Advice Letter

Payment advice letter could refer to one of two things:
  • A payment reminder letter that a supplier or vendor sends to a client to ask them to pay an overdue invoice.

  • A letter sent by a client to inform a provider that they made a payment.
In this article, we are going to explore both types of letters.

How to write a letter to remind a customer of their payment?

  • Mention the unpaid invoice number, the date of the invoice, and the amount that needs to be paid.
  • Make it clear to the client to which account this invoice belongs to and for against which service.
  • Specify a deadline for the payment.
  • Explain what happens if the payment is not made on time.

Sample Letter
