Before the due date
A friendly reminder, a few days before.
Automation · 2026 edition
Chasing a customer takes time and a bit of courage. The result: you wait, and your cash flow suffers. An automatic reminder goes out at the right time, in the right tone, for every invoice. Here is the schedule to follow, template messages and the rules to respect.

In short
Automatic payment reminders send scheduled messages based on each invoice's due date: a friendly reminder just before, a follow-up just after, then a firmer message. They stop as soon as payment is received. You stay in control of the last step, the formal demand for payment, and of the customers you prefer to handle yourself.
A friendly reminder, a few days before.
A short reminder, with the invoice attached.
Late payment interest and compensation mentioned.
You approve the formal demand yourself.
Adapt it to your payment terms. Consistency is what matters: every invoice follows the same sequence.
| When | Message | Tone |
|---|---|---|
| D-3 before the due date | Reminder of the invoice, amount and date | Friendly, helpful |
| D+1 after the due date | The invoice appears unpaid, here is the payment link | Neutral, factual |
| D+10 | Second reminder, asking for a payment date | Direct |
| D+20 | Reminder of late payment interest and the €40 compensation | Firm |
| D+30 | Phone call or personal message | Human |
| D+45 | Formal demand by recorded delivery, approved by you | Formal |
Reminders stop automatically as soon as the payment is matched. A customer who has already paid should never receive a reminder.
In the EU, the Late Payment Directive (2011/7/EU) sets common rules for invoices between businesses, which each country applies in its own law. They give weight to your reminders.
30 days by default. More than 60 days only if expressly agreed and not grossly unfair. Some countries set stricter limits.
It runs from the day after the due date, with no reminder needed.
If no rate is agreed, at least the European Central Bank reference rate plus 8 points. Some countries set a higher rate.
A fixed compensation of at least €40 per late invoice is owed by the business customer.
Show the due date and your late payment terms on the invoice. Check what your country requires.
Late payment interest and the €40 compensation do not apply in the same way. Stick to courteous reminders.
A successful reminder is short, polite and makes paying easy.

A friendly reminder a few days before the due date, then a reminder the day after, at D+10 and at D+20. After 30 to 45 days, move on to a phone call, then a formal demand for payment.
The invoice number and date, the amount, the missed due date and a simple way to pay. Keep it short and polite.
Between businesses in the EU, yes: under the Late Payment Directive, it is due automatically for every invoice paid late. Check whether your country also requires it to appear on the invoice.
Yes, if it goes out when they have already paid. That is why it must be linked to your payment tracking and keep a courteous tone.
Send a formal demand for payment by recorded delivery, then consider a court payment order procedure under your country's rules.
