How consultants bill
Consultants usually bill a day rate, a fixed project fee, or a monthly retainer. Expenses (travel, materials) are often billed on top as separate lines.
What to put on a consultant invoice
- The engagement or SOW reference so the client's finance team can match it to the agreement.
- Whether the fee is a day rate, fixed fee or retainer — and the period it covers.
- Reimbursable expenses itemised separately from your fee.
- The essentials every invoice needs: your details, the client's, a unique number, issue and due dates, an itemised list, the total, and how to pay.
