Published July 2026 · Updated July 2026

Key takeaways

  • Set clear payment terms upfront so expectations are agreed.
  • Follow a polite, escalating reminder schedule.
  • Make paying as easy as possible.
  • Know your right to charge interest on overdue commercial invoices.

Set terms upfront

Agree payment terms before you start, on your quote and invoice. Clear due dates and accepted payment methods remove ambiguity and give you a firm footing to follow up.

A reminder schedule

Have a set routine: a friendly reminder just before the due date, a polite nudge the day after, and firmer follow-ups at set intervals. Consistency matters more than tone, and most late payments are simply oversights.

Make paying easy

Include a clear amount, due date and payment options on every invoice. The fewer steps between the customer and paying, the sooner the money arrives.

Know your rights

For overdue commercial (business-to-business) invoices, you may be entitled to charge statutory interest and a fixed recovery cost under UK late-payment rules. Even mentioning this politely can prompt payment.

Worked example

Day −2: friendly 'invoice due soon' note
Day +1: polite 'now overdue' reminder
Day +7 and +14: firmer follow-ups, mention terms
Consistency gets most invoices paid without friction.
