Payment reminders: 3 levels from polite nudge to final notice

Without a system, 15–20% of your customers pay late. A three-level approach — friendly, formal, final notice — gets 95% paid on time.

The biggest cashflow win for an SMB is payment discipline. A three-level reminder process keeps things professional without burning bridges.

Level 1: friendly reminder — day 3 after due date

"Hi, invoice no. X was issued on [date] and was due on [date]. You may have missed it — link to invoice here." 80% pay within 5 days.

Level 2: formal reminder — day 14

"We have not yet received payment for invoice X. We kindly request that you settle this within 7 days. Please include the invoice number with your payment." 15% of the first group follows up.

Level 3: final notice — day 28

"This is our final notice. If payment is not received before [date], we will charge administrative costs in accordance with the law (€40 minimum) and transfer the outstanding amount to a collections agency." 4% of the total group.

The last 1%

Collections or write-off. See bad debts.

Automate it

Every step should be automatic — email on day 3, day 14, day 28. Your manager gets a notification when the final notice goes out (that's when a phone call is sometimes worth it). See recurring invoicing for the technical setup.

Tone of voice by customer type

• Regular customer: a bit more breathing room (day 5–10–21 instead of 3–14–28).
• New customer: stick to the default (3–14–28) so your standards are clear from the start.
• Large customer with a payment cycle: align with their cycle, not your defaults.
