How to Request Payment on an Overdue Invoice

Chasing an overdue invoice is uncomfortable — but leaving it unpaid is worse. Most late payments happen for mundane reasons: the invoice got buried, the approver was away, the client's finance process is slow. A clear, professional follow-up is the fastest way to move it through.

Original Message

Dear [Client Name],

I hope this message finds you well. I'm following up on invoice #[number] for [amount], which was due on [date] and remains outstanding.

I understand things can get busy, so I wanted to send a gentle reminder before this becomes more overdue. For your convenience, I've attached the invoice again. If there are any issues with the invoice or the payment process, please let me know and I'll do whatever I can to resolve them quickly.

Could you let me know when I can expect payment? Thank you.

Best regards,
[Your Name]

When to Use This Template

  • When an invoice is 1-7 days past the due date and you want to send a soft reminder
  • When payment is 2+ weeks overdue and a firmer tone is needed
  • When the client has not acknowledged or responded to a previous reminder
  • When you need to escalate with a reference to your late fee policy

Common Mistakes to Avoid

Waiting too long to follow up: The sooner you follow up, the higher the likelihood of quick payment.
Being apologetic about chasing payment: You're owed this money. A professional, confident request is completely appropriate.
Not including the invoice details in the follow-up: Include the invoice number, amount, and due date in every follow-up.

Frequently Asked Questions

How many times should I follow up before escalating?

Typically 3 times: a polite reminder at a few days overdue, a firmer follow-up at 2 weeks, and a final notice at 4 weeks.

What if the client says they never received the invoice?

Resend it immediately. Note the date you resent it and establish a new clear payment deadline.
