Chasing an invoice is a three-letter process, and most freelancers send the wrong one first. Pick the stage, fill in six fields, and get a letter that reads like it was written by someone who expects to be paid — with the right statutory interest wording for your jurisdiction. Download it as Word or copy the text.
Send them roughly 7–14 days apart, always in writing, always to a named person. The paper trail is what makes stage three credible.
This page is free and always will be. If you'd rather not assemble the paperwork yourself, the Freelancer Legal & Admin Pack is 8 editable Word documents with every clause above already in them — contractor agreement, NDA, invoice, all three late-payment letters, SOW, privacy policy, terms of service and a payment plan agreement. One-time $17, no account, instant download.
