Firm Invoice Chase Letter
A firmer chase for an invoice that is now well overdue — clear about consequences and backed by your statutory right to charge interest.
When to use this
Reach for this once an invoice is 30 or more days overdue and earlier reminders have gone unanswered. It stops assuming good faith: it spells out clear consequences and references your right to statutory interest under UK law.
Sample excerpt
Despite my previous reminders, invoice #1042 for £1,800 remains unpaid — now 30 days overdue. Under the Late Payment of Commercial Debts (Interest) Act 1998, I am entitled to charge statutory interest at 8% above base rate from the day after the due date. I ask that you settle this within 7 days to avoid further action.
Why it works
Citing the Late Payment of Commercial Debts (Interest) Act 1998 signals that you know your rights and are prepared to use them, which often shifts an invoice up a slow-paying client’s priority list. NudgeBadger works out the interest you’re owed and words it correctly, so the letter is firm and accurate rather than just annoyed.
