We understand overdue invoices or late payments are indeed annoying for any business. And it’s important to stay on top of outstanding payments to keep your business running smoothly. Therefore, this article outlines the best email templates to professionally remind clients of overdue payments and charges without spending much time.

How to Write an Email to Follow up on Outstanding Payments

Follow-up emails are vital in business if you want to maintain the effectiveness of your sales and marketing strategies. If a customer fails to pay, you must clarify what the payment agreement entails and address the reason for missing the payment.

Tips to Write a Follow-up Email for Outstanding Payments:

  • Keep it brief & polite – Get to the point quickly and clearly state your email’s purpose. Make sure to use a courteous and professional tone.
  • Use persuasive language – Make it clear that payment is overdue and emphasize the importance of timely payment.
  • Include all relevant information – Provide details about the outstanding payment, including the amount owed, invoice date, etc.
  • Avoid making threats or ultimatums – This will only aggravate the situation and may damage your relationship with the client.
  • Offer a payment plan or alternative arrangement – If the client struggles to pay in full, offer to set up a payment plan. You could also explore other options, such as partial payment.
  • End on a positive note – Thank the client for their time and reiterate your willingness to work with them to resolve the issue.
