Describe the fixed-fee scope
A fixed fee still needs an identifiable project, deliverable, or billing milestone. Use the same project name and scope language that appears in the accepted proposal so the client can match the documents.

Common mistakes
Summarize scope in the line description and tie payment to deliverables. Fixed-fee projects still need a due date and a note on what happens if scope expands.
Show how this invoice fits the payment schedule
State whether the charge is a deposit, progress payment, milestone, or final balance. Display prior payments and the remaining amount when they help the client understand the full project total.
Keep additions out of the base fee
List approved scope additions separately and reference the change record. Avoid using the invoice to introduce work or pricing the client has not already had an opportunity to review.
