A polite payment reminder template for an unpaid invoice
Use the checked outstanding balance, the invoice reference and a clear timing question in your next follow-up.
A useful payment reminder makes it easy for the client to identify the invoice and reply. Before writing, check the amount still outstanding against your accounting records. DueSparrow’s free writer uses the figures you enter; it does not verify receipts or send the message.
Check the amount and context
Confirm the invoice reference, original total, payments received and remaining balance. Check the latest client reply before drafting another reminder. A payment promise or a question about the invoice may call for a different next step.
For an illustrative $1,500 invoice with $500 received, the remaining amount is $1,000. Enter the original amount and actual received payments, not the amount you hope will arrive.
- Invoice reference and due date
- Payments checked in accounting records
- Latest promise, question or dispute
Keep the message factual
Example: “Hi Alex, I’m following up on invoice INV-1042. Thank you for the $500 payment; our records show $1,000 remaining from the $1,500 invoice. Could you confirm when the balance is scheduled for payment? If you need another copy of the invoice, please let me know.”
Replace all sample details and confirm the recipient. If your records may be out of date, check them before sending. Avoid adding claims about penalties, legal action or agreed terms that you have not verified.
- Identify the invoice
- State the remaining balance
- Ask a clear question about timing
Review and send from your own email
Use the free payment reminder writer to prepare a draft, then copy or download it. Review every number and send it through your normal communication channel. No message is sent by the free tool.
Record the reply and the next follow-up date. If the client raises an issue, discuss that issue rather than continuing ordinary reminders. A saved DueSparrow workspace helps organize the records; it is separate from your accounting and payment systems.
- Review the draft and recipient
- Send deliberately
- Record the actual reply
