How to write a writer invoice
- Give each piece its title, so the client can match it to what was published.
- Say whether your price is per word, per piece or per hour.
- Note when rights or ownership transfer to the client.
- Invoice when a piece is approved, not when it is published, unless agreed otherwise.
