What to include in a copywriter invoice
- Piece title and word count. Each article or page by title with its word count or agreed length, which is clearer than an hourly figure and easy for an editor to check.
- Rate unit on each line. Whether the line is priced per word, per 1,000 words, per page or per piece, so the client can recheck the total without asking you.
- Revision rounds included. How many rounds of edits the price covers and any extra rounds billed separately, which stops a rewrite being treated as a small correction.
- Research and interviews. Interviews, source research or keyword research billed as its own line when it goes beyond what the per word rate assumed.
- Kill fee. The part of the fee owed if the client cancels after work has started, as agreed in the contract, billed on its own line for the cancelled piece.
- Rights and usage. Which rights transfer on payment, such as all rights, first rights or work made for hire, so ownership is clear once the invoice is paid.
- Client PO or project code. The purchase order number or project code the client's accounts team asks for, because invoices without one often stall in an approval queue.
- Delivery and publication date. When the piece was delivered, and the URL or issue if already published, since many clients count payment terms from delivery or publication.
