Send it on letterhead by email after your WhatsApp reminders, and keep a copy: it is the record you will need if the matter goes further.

This outstanding payment reminder letter format gives you three versions (first, second and final) in one editable Word file. Fill the brackets, put it on your letterhead and email it as a PDF. ## Outstanding payment reminder letter format: first reminder **Subject:** Payment reminder: invoices outstanding as of [date] Dear [Customer name], our records show the following invoices for [service / AMC] at [site] remain unpaid: - Invoice [No.] dated [date], Rs [amount], [days] days overdue - Invoice [No.] dated [date], Rs [amount], [days] days overdue - Total due: Rs [total] We request you to clear the amount by [date] by UPI ([UPI ID]) or bank transfer ([account details]). If you have already paid, please share the payment reference so we can update our records. Regards, [Name], [Company], [Phone] ## Second reminder **Subject:** Second reminder: Rs [total] outstanding Dear [Customer name], further to our letter of [date], the amount of Rs [total] is still outstanding. Please let us know if there is any issue with the service or the invoice, so we can resolve it. Otherwise we request payment by [date]. ## Final reminder **Subject:** Final reminder before suspension of service Dear [Customer name], despite our reminders dated [dates], Rs [total] remains unpaid. As per clause [no.] of our agreement dated [date], we will pause scheduled visits from [date] if payment is not received. We value your business and would prefer to settle this directly. ## What to attach - A statement of account: every invoice, payment and the balance. - Copies of the unpaid invoices. - For AMC customers, the visits completed in the period, so the customer sees what they are paying for. ## Mistakes that delay payment - Sending the letter to the person who booked the service instead of the person who pays. - A total that does not match your own invoices. One wrong number and the customer stops trusting the whole letter. - Threats you will not carry out. State only the next step you will actually take. ## Keep the statement ready A reminder letter is only as good as the statement behind it. In ServicePilot each payment is recorded against the invoices it clears, so the balance and days overdue per customer come from the [payments record](https://servicepilot.in/features/payments-and-collections/), not from a separate sheet.

Quote the clause rather than inventing a rate. **Q: Is a reminder letter the same as a legal notice?** A: No. A legal notice is usually sent by a lawyer. A reminder letter is your own business letter and often settles the matter. **Q: Can I send it by email?** A: Yes. Email with the letter as a PDF is normal and gives you a dated record. ## Related articles [Quotes & Payments Quotation Follow Up Message: WhatsApp and Email Samples Quotation follow up message samples for WhatsApp and email: day 1, day 3, day 7 and last follow-up, for AMC, installation and repair quotes.
