What is a Past Due Invoice Email?

A past due or overdue invoice email is an email that a company sends to a client or customer to remind them that an invoice payment deadline has passed or the invoice is now overdue.

Importance of Sending Past Due Invoice Emails

When customers or clients do not comply with a sales invoice's terms, it could endanger your business's financial health.

If clients don't act promptly on your initial invoice email, sending past due invoice emails is important because it helps ensure you receive overdue payments.

  • Mention the invoice number and the due date in the email so the customer can easily identify which invoice is overdue.
  • Explain why the payment is now overdue, and include any late fees that may now apply.
  • Offer payment options and provide clear instructions for payment.

When to Send a Past Due Invoice Email?

Before sending a past due invoice email, you must know when an invoice becomes overdue. 

When writing an invoice, you should have a clearly stated due date for client’s reference.

However, if the due date to submit payment has passed, the invoice is now considered past due, and a reminder will need to be sent.

How to Choose the Right Tone for a Past Due Invoice Email?

When reminding a client about a past due invoice, it's important to be mindful of your tone. Avoid using accusatory language, as this may cause the client to become defensive.

Try offering help in your final notice if the client struggles to pay the invoice. Some effective reminders that you can use in the past due invoice email are:

  • "We noticed that the payment for Invoice ABC is now five days overdue."
  • "Please let us know if there are any issues or reasons due to which you have not paid the invoice."
  • "Can we work out a payment arrangement that will be easier for you? We are willing to work together so that we can both agree on a plan."
  • "Please contact us immediately and let us know when we can expect the payment to arrive."
