How to write a freelancer invoice
- Describe each deliverable so the client's accounts team can match it to the project without asking.
- Bill extra work separately and say who agreed it, so scope changes do not turn into disputes.
- Invoice as soon as a milestone is delivered rather than at the end of the month.
- Agree your payment terms and late fee in your contract or quote before you start.
