How to write a consultant invoice
- Separate the retainer from extra work billed by the hour, so the client sees what was outside the agreement.
- Add a short summary of the work done; it reminds the client of the value they received.
- Bill retainers at the start of the month and hourly work at the end.
- Get the engagement letter signed before you start.
