A good invoice payment reminder states the invoice number, amount, due date, payment method, and the action you want. Start with a friendly reminder, then become more direct only when the payment is actually overdue.

How to approach it
- Confirm the facts before writing: invoice number, balance, due date, accepted payment method, and the correct recipient.
- Lead with context rather than blame. Say what the invoice is for, then ask the client to confirm when payment is scheduled.
- Make the next step easy. Attach the invoice if appropriate, include a payment link or instructions, and give a reasonable reply date for overdue balances.
Useful wording examples
- Subject: Friendly reminder — invoice 1048 due June 30

Hi [Client name],
A quick reminder that invoice [number] for [amount], dated [date], is due on [due date]. I’ve attached a copy for convenience. Could you confirm the expected payment date, or let me know if anything needs clarification?
Thank you,
[Your name]
What to avoid
