The UK has a late payment problem
Built to chase unpaid invoices, without the anxiety
Existing tools are too expensive, too complex, or too aggressive. NudgeBadger is different.
Automatically calculates statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998. Your rights, included by default. Try our free late payment interest calculator to see the figures for your own invoice.
Use it without signing in and nothing is stored. Sign in and your letters are saved securely to your account, never shared, never sold.
Every letter is calibrated to get you paid without burning the bridge. Friendly first. Firm when needed. Formal only as a last resort.
UK law, UK tone, UK payment culture. Not a US tool with a pound sign stuck on. Built specifically for British freelancers and small businesses.
