Overdue Invoice Email Templates That Actually Work

Updated March 2026

Knowing what to say when chasing a late payment is half the battle. Here are four templates you can copy and customize for your business, one for each stage of escalation.

Template 1: Friendly Reminder (1 day overdue)

Subject: Friendly reminder — Invoice #[NUMBER] is past due

Hi [NAME],

This is a quick reminder that invoice #[NUMBER] for $[AMOUNT] was due on [DATE]. If you've already sent payment, please disregard this message.

Otherwise, we'd appreciate payment at your earliest convenience. [PAYMENT LINK]

Thanks,
[YOUR NAME]

Why it works: Assumes the best, gives an easy out if they've already paid, includes a payment link.

Template 2: Firm Follow-Up (7 days overdue)

Subject: Payment overdue — Invoice #[NUMBER], 7 days past due

Hi [NAME],

Our records show that invoice #[NUMBER] for $[AMOUNT] is now 7 days past due (due [DATE]).
