1. Clear subject line
Put the invoice number in it, so the client can find it later.
2. Reply in the same thread
Send follow-ups as replies, so the whole history stays in one place.
3. Get firmer slowly
Start friendly. Mention late fees only in the final notice.
How do I write a polite payment reminder email?
Keep it short and specific. Use a clear subject line with the invoice number, greet the client by name, mention the amount, what it’s for and the due date, and end with a simple question like "Could you let me know when I can expect it?" Assume they forgot, not that they refused.
What is a good subject line for a payment reminder email?
Clear beats clever. Include what it is and the invoice number, for example "Friendly reminder: payment due on 20 October – Invoice INV-102" or "Overdue payment – Invoice INV-102". Clients can find it easily later, and it’s less likely to be ignored.
When should I send payment reminder emails?
A common schedule is: a friendly reminder 2–3 days before the due date, one on the due date, then follow-ups at 3 days, 1 week and 2 weeks overdue. Weekday mornings tend to get the fastest replies.
How do I write a final notice for an unpaid invoice?
Stay professional and factual. Mention your earlier reminders, give a clear deadline (for example 3 or 7 working days), and say what happens next: pausing work, late fees as per your terms, or formal recovery. Only mention consequences you’re really prepared to follow through on.
Can I charge interest on late payments in India?
If you’re registered as an MSME (Udyam) and your client is a business, the MSMED Act lets you claim compound interest at three times the RBI bank rate on payments delayed beyond the agreed date (maximum 45 days). Otherwise, late fees apply only if they were agreed in your contract or invoice terms.
DueBlink sends polite reminder emails automatically when a client goes quiet, and gets firmer step by step, so you never have to chase by hand.
