How to follow up an unpaid invoice

Most late payments are forgotten, not refused. A short, polite reminder at the right time is usually all it takes, and it keeps the customer.

Before it is late

Send the invoice the day the work is done, with the due date and your bank details on it. An invoice sent a week late is paid a week late.

First reminder: a day or two after the due date

Hello, this is a gentle reminder that invoice INV-2026-00042 for AED 1,250 was due on 10 October. Here is the link again. Thank you.

Second reminder: a week later

Hello, invoice INV-2026-00042 for AED 1,250 is still open. Could you let me know when we can expect the payment? If there is any question about the invoice, please tell me.

Third reminder: after two weeks

Hello, invoice INV-2026-00042 for AED 1,250 is now two weeks overdue. Please arrange the payment this week, or call me so we can agree a date.

What helps

  • Always give the invoice number, the amount and the due date
  • Send the invoice link again so the customer does not have to search
  • Offer an easy way to pay: bank details on the invoice, or an online payment link
  • Keep a note of what was said and when
  • Call rather than message when two reminders have had no reply

How Tichkuly CRM helps

Short answers

How soon should I remind a customer?

A day or two after the due date is reasonable. Earlier than that, a reminder can feel pushy.

Should I remind by WhatsApp or by email?

Use what the customer answers. For most small-business customers in the UAE that is WhatsApp.

Does Tichkuly send reminders automatically?

No. It shows you who to remind and opens the chat with the message ready. You press send, so nothing goes out without you.
