What to write when an invoice is overdue
Use the generator above when you need a complete email. Use these short answers when you need the right wording, timing, or payment reminder format before sending.
payment reminder email
Write a short, professional email that references the invoice, amount, due date, payment link, and next step. Keep the first reminder polite, then become more direct as the invoice gets older.
reminder email sample
Use a sample email as a starting point, then add your client name, invoice number, amount due, original due date, and contact details before sending.
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.

Frequently Asked Questions
What is a payment reminder email?
A payment reminder email (also called a dunning email) is a professional message sent to clients whose invoices are overdue. It politely or firmly requests payment, depending on the tone. Our free generator creates three variants — friendly, formal, and urgent — so you can choose the right approach for each situation.
How many days after the due date should I send a payment reminder?
Most businesses send a friendly reminder 1–3 days after the due date, a second reminder at 7–14 days, and a formal or urgent notice at 30+ days. Our generator adapts the message based on how many days the invoice is overdue, so you always sound appropriate to the situation.
