Late Payment Reminder Email Templates That Actually Get You Paid
Chasing overdue invoices is uncomfortable—but necessary. Copy these proven late payment reminder email templates and learn when to send each one.
Chasing money is never fun. But a well-written late payment reminder email converts awkward silence into cash in your account—without destroying client relationships.
The Psychology of Payment Reminders
Most overdue invoices are not malicious. Clients forget, approvers are on vacation, or your invoice never reached accounts payable. Your job is to make payment easy and obvious.
Always attach the original invoice PDF and include the invoice number in the subject line.
Reminder #1: Friendly Pre-Due Notice (3–5 Days Before)
Subject: Reminder: Invoice #[NUMBER] due [DATE]
Hi [Name],
Hope you are doing well. Just a quick heads-up that invoice [NUMBER] for [AMOUNT] is due on [DATE].
I have attached a copy for convenience. Please let me know if you need anything from my side for processing.
Thank you,
[Your name]
Reminder #2: Polite Overdue Notice (2–3 Days After Due Date)
Subject: Following up: Invoice #[NUMBER] – [AMOUNT]
Hi [Name],
I wanted to follow up on invoice [NUMBER] for [AMOUNT], which was due on [DATE].
If payment has already been sent, please disregard this note—thank you! Otherwise, I would appreciate an update on timing so I can plan accordingly.
Payment details are on the attached invoice. Happy to answer any questions.
Best,
[Your name]
Reminder #3: Firm but Professional (10–14 Days Overdue)
Subject: Action needed: Invoice #[NUMBER] now overdue
Hi [Name],
Invoice [NUMBER] for [AMOUNT] is now [X] days past due. I understand delays happen—could you confirm when I can expect payment, or if there is an issue I should address?
I value our working relationship and want to resolve this quickly. Please reply by [DATE] so we can close this out.
Thank you,
[Your name]
