Late payment is one of the biggest financial challenges facing UK small businesses. Research consistently shows that small businesses are owed billions of pounds in overdue invoices at any given time. Here’s how to reduce late payments and deal with them when they occur.
Prevention Is Better Than Cure
Clear payment terms on every invoice, agreed upfront. Credit checking new clients before extending payment terms. Requiring deposits for larger jobs. Shorter payment terms — 14 days rather than 30 — for standard invoices. All of these reduce your exposure to late payment.
💡 Key takeaway
UK law allows you to charge 8% above base rate interest on overdue invoices automatically — most businesses never use this right.
Automated Payment Reminders
Cloud accounting software like Xero lets you set up automatic payment reminders — sent by email before and after the due date. This alone dramatically improves payment speed without any awkward conversations. Most clients pay within hours of a polite automated reminder.
Statutory Interest on Late Payments
Under the Late Payment of Commercial Debts Act, you’re entitled to charge 8% above the Bank of England base rate on overdue business-to-business invoices, plus a fixed debt recovery charge of £40–£100 depending on the debt size. Many businesses don’t realise they can charge this.
Escalating Your Response
If automated reminders don’t work: call the client directly. Discuss payment plans if there are genuine financial difficulties. Send a formal Letter Before Action. Consider using a debt collection agency or taking the matter to the County Court — straightforward for debts under £10,000.
Credit Control as a Routine
Make credit control a regular, scheduled activity — not something you do only in a crisis. Review your aged debtors report weekly. A bookkeeper can produce this report and flag overdue invoices before they become a significant problem.
