Proofline helps UK freelancers and small service businesses recover overdue B2B invoices. It calculates statutory interest and compensation, organises the chase history into a clear chronology, and creates a factual payment request. Case details stay in the browser, and the paid Recovery Pack produces a printable evidence register, final request and seven-day action plan.
Late payment advice is scattered across calculators, email templates and legal guidance. Proofline was built to turn those disconnected steps into one private, practical workflow that helps a freelancer see what happened, what is recoverable and what to do next.
