overdue invoice email

An overdue invoice email should state how many days the invoice is past due, repeat the amount owed, attach or link the invoice, and ask for a specific payment date.

friendly payment reminder

Send a friendly reminder 1 to 3 days after the due date if you want to preserve the relationship and assume the invoice was simply missed.

final payment reminder

Use a final reminder only after earlier follow-ups. Mention late fees, service pause terms, or collection steps only when those terms were already agreed.

Reminder email sample sequence

Three overdue invoice email examples

A reminder email should become clearer as the invoice ages. The tone can stay professional without sounding vague or aggressive.

First reminder

1 to 3 days overdue

Subject: Quick reminder: invoice payment due

Hi [Client Name], I wanted to follow up on invoice [Invoice Number] for [Amount], which was due on [Due Date]. If payment has already been sent, thank you and please disregard this note. Otherwise, you can pay here: [Payment Link].

Second reminder

7 to 14 days overdue

Subject: Follow-up on overdue invoice [Invoice Number]

Hi [Client Name], our records show invoice [Invoice Number] for [Amount] is still unpaid. Could you confirm when payment will be processed, or let me know if you need another copy of the invoice?

Final reminder

30+ days overdue

Subject: Final notice for overdue invoice [Invoice Number]

Dear [Client Name], invoice [Invoice Number] for [Amount] remains unpaid after prior reminders. Please remit payment by [Date] or contact us immediately to resolve the outstanding balance.
