Invoice Reminder Email Templates That Actually Get You Paid
The right words at the right time are the difference between getting paid and getting ghosted. Most reminder emails fail for the same two reasons: they are sent too late, and they use the same friendly tone regardless of how overdue the invoice is.
Below are five copy-and-paste templates we use at Duefy, organized by where the invoice is in its lifecycle. Each one is tested on real client accounts. Adjust names and amounts; keep the rhythm.
Template 1 — Pre-due nudge (3 days before)
Subject: Friendly reminder: Invoice INV-001 due Friday
Body:
Hi [First name],
Just a quick heads-up that invoice INV-001 for $3,200 is due on Friday, May 1. Pay link is below for one-click payment.
Thanks for working with us!
[Your name]
Why this works: Friendly, low-pressure, removes the "I forgot" excuse before it happens. About 60% of clients pay within 48 hours of this email.
Template 2 — Due-date reminder
Subject: Invoice INV-001 — due today
Body:
Hi [First name],
Invoice INV-001 for $3,200 is due today. You can pay in one click using the link below.
If you need a different payment method or have any questions, just reply to this email.
Thanks,
[Your name]
Why this works: Still friendly, but the subject line lands on the due date so it surfaces in their inbox at the right moment. Offering alternatives ("reply for other methods") removes payment friction.
Template 3 — Polite follow-up (7 days overdue)
Subject: INV-001 — 7 days past due
Body:
Hi [First name],
Following up on invoice INV-001 for $3,200, which was due on May 1 and is now 7 days past due.
I want to make sure this did not slip through. If you have already initiated payment, please ignore this. Otherwise, you can use the link below.
If something is blocking payment on your end, let me know and we can figure it out.
Thanks,
[Your name]
Why this works: Acknowledges the possibility of an oversight without accusing. The "if something is blocking payment, let me know" line is critical — it invites a reply, which is what you want at this stage. See how to ask politely for variants.
Template 4 — Firm reminder (14 days overdue)
Subject: Action needed: INV-001 now 14 days overdue
Body:
Hi [First name],
Invoice INV-001 for $3,200 is now 14 days past due. I have not heard back from my previous emails.
Please let me know the status by [date 5 business days out]. If you are unable to pay the full amount, we can discuss a payment plan.
If I do not hear back, I will need to follow up directly by phone.
[Your name]
Why this works: Sets a deadline, opens the door to a payment plan (often the real reason people go quiet), and signals escalation. Avoid threatening language — clear consequences are enough.
Template 5 — Final notice (30 days overdue)
Subject: Final notice: INV-001 — 30 days overdue
Body:
Hi [First name],
This is a final notice that invoice INV-001 for $3,200 is now 30 days past due.
Per our agreement, a late fee of $48 (1.5% per month) has been added, bringing the balance to $3,248.
If full payment is not received by [date 7 days out], this account will be referred to collections.
[Your name]
Why this works: Specific deadline, specific consequence, specific number. No emotion. At this stage, vague language signals weakness. See how to charge late fees legally before adding them.
How to actually send these
Pasting these manually defeats the point — by the time you remember to follow up, you are already late. Duefy sends these automatically based on the invoice due date, escalates the tone, and pauses the whole sequence if the client replies.
