Payment reminder message to customer

A payment reminder message to customer is the one most owners put off, then send too late and too angry. The real trap is the gap: you wait two weeks hoping the money arrives, so the first message the customer sees already sounds like a complaint. Most late payers just forgot. This page gives you a message for every stage: before the due date, on the day, 3 days late, 14 days late, 30 days late and a final notice. There are versions for a customer who promised to pay and did not, one for a part payment, and four in Bahasa Malaysia.

Tap any green message to copy it.

When to send it

Start before the money is late. A reminder 3 days before the due date gets paid far more often than a chase after it, because nobody has to admit they forgot. Send between 9am and 5pm on a working day. Avoid Friday afternoon and the day before a public holiday, when nobody in accounts will act on it. Always attach or link the invoice again. "Which invoice?" is the most common reason a payment stalls for another week.

1. Friendly, 3 days before it's due

Use for regular customers and anyone on 30-day terms.

You → customer
Hi [Name], a quick heads-up that invoice [#INV-0123] for [RM amount] is due on [date]. You can pay here: [pay-link]. Thanks!

2. On the due date

Use when the day arrives and nothing has come in yet.

You → customer
Morning [Name], invoice [#INV-0123] for [RM amount] is due today. Bank details: [bank], [account no.], [account name]. Please send the slip here once done so I can match it. Thank you 🙏

3. 3 days late

Use when it's probably an oversight. Assume it is.

You → customer
Hi [Name], I haven't seen payment for invoice [#INV-0123] ([RM amount], due [date]) yet. It may have crossed with this message. If it's already paid, just send me the slip and I'll update it.

4. 3 days late, sent to accounts

Use when your contact is the buyer, but someone else pays.

You → customer
Hi [Name], could you help me forward invoice [#INV-0123] to whoever handles payments? It was due on [date]. If you share their number, I'll follow up with them directly so I don't keep bothering you.

5. 14 days late

Use when the friendly ones got no reply. Ask for a date.

You → customer
Hi [Name], invoice [#INV-0123] for [RM amount] is now 14 days overdue. Can you let me know the date you'll be paying? I need to plan this week's stock orders around it.

6. After a broken promise

Use when they gave a date and it passed.

You → customer
Will pay by Friday boss
Hi [Name], you mentioned payment by Friday [date] for invoice [#INV-0123], but I haven't received it. Can you confirm a new date today, and whether it will be the full [RM amount]?

7. Part payment received, balance still due

Use when they paid some of it and went quiet.

You → customer
Hi [Name], thanks for the [RM paid] received on [date]. The balance of [RM balance] on invoice [#INV-0123] is still open. Can you settle it by [date]? Same account: [account no.].

8. 30 days late, holding new orders

Use for trade customers who keep ordering while the old invoice sits.

You → customer
Hi [Name], invoice [#INV-0123] for [RM amount] is now 30 days overdue. I'll need it cleared before I can send your next order. Once the slip comes through, I'll release it the same day.

9. Final notice

Use once, with a real date and a real next step you will take.

You → customer
Hi [Name], this is a final reminder for invoice [#INV-0123], [RM amount], overdue since [date]. Please pay by [final date]. After that, I'll have to put your account on hold and pass this to [our accounts team / a collection agent]. I'd rather sort it out between us, so call me if there's a problem.

In Bahasa Malaysia

What not to send

  • "Any update?" with no invoice number. It gives the customer nothing to act on and an easy reason to ignore you.
  • A threat in the first late message. You lose a customer who simply forgot, and you have nothing left to escalate to.
  • A final notice you won't follow through on. Next time, they'll know your deadlines are soft.
  • Reminders in a group chat. Chasing one customer's debt in front of others embarrasses them and rarely speeds things up.
  • A screenshot of the invoice without the amount typed out. Customers search chats by text, and an image can't be found later.

Stop typing these by hand

Cupbots runs on your own WhatsApp number. It takes orders, sends invoices with a pay-link and answers "any update?" in the chats you already use, so messages like these go out on time without you.

FAQ

How do you politely remind a customer to pay?

Send the reminder before the due date, not after. Name the invoice number, the amount and the date, and put the pay-link or bank details in the same message so they can pay without asking. Keep it to two or three lines. A short message with everything in it reads as admin, not as chasing.

How many days after the due date should I send a reminder?

Send one on the due date, another 3 days after, and a firmer one at 14 days. At 30 days, call or send a final notice with a clear date and what happens next. Waiting longer than a week for the first late reminder tells the customer that paying late costs nothing.

Is it rude to send a payment reminder on WhatsApp?

No, if the customer already deals with you on WhatsApp. Most small business customers in Malaysia and Singapore prefer it to email, because they see it sooner. Keep the tone the same as your usual chats, and send it during working hours, not at night or on a public holiday.

What should I write when a customer keeps promising to pay?

Quote their own promise back to them with the date they gave, then ask for one specific thing: a date and an amount. Avoid open questions like "any update?", which invite another vague reply. If the second promised date passes, move to the final notice.
