Chase an unpaid invoice without ruffling feathers

When to follow up, what to write, on which channel: a simple reminder schedule and ready-to-copy messages to get paid without losing the client.

A late invoice is almost never a sign of bad faith. Most of the time, it was forgotten, lost in a WhatsApp thread, or is waiting for someone else's approval. A good reminder helps the client pay; it doesn't accuse them.

Prevent before you chase

The best reminder is the one you never have to send. Three habits greatly reduce late payments:

Announce the payments in the quote. Deposit, steps and balance in black and white, with dates.
Send the invoice at the right moment. Right after a step is approved, when the client is happy with the work.
Make paying easy. A link, payment methods they already use (mobile money, card, transfer) and the exact amount in their currency.

A simple reminder schedule

3 days before: a friendly heads-up that the due date is coming.
3 days after: a short follow-up, with the payment link.
10 days after: a more direct message, offering to talk if something is holding things up.
20 days after: a phone call. At this point, a conversation sorts out more than yet another message.

Ready-to-copy messages

Before the due date: "Hi Awa, just a quick reminder: invoice INV-2026-014 for the Mockups step is due on Friday. You can pay it here with Orange Money or by card. Thanks!"

After the due date: "Hi Awa, I'm following up on invoice INV-2026-014, which was due on Tuesday. Is everything OK on your end? The payment link is still active."

When things are stuck: "Hi Awa, invoice INV-2026-014 is still outstanding. If paying it all at once is a problem, we can split it into two payments. Let me know what works for you."

What to avoid

Chasing payment in a WhatsApp group where other people can read it.
Threatening to stop work at the very first delay.
Carrying on delivering without saying anything while several invoices pile up.
