Hours, rate and role
List consultant, hours and rate per line when billing time and materials.
Reimbursable expenses

Payment terms
Match the terms agreed in your contract, and show the due date clearly.
Tips for getting paid on time
- Add the client's PO number in the notes field if they use one.
- Bill retainers at the start of the period and time-based work at the end.
- Keep expense receipts available in case the client asks for backup.
Invoice requirements such as tax IDs, VAT or sales tax lines and numbering differ by country. Check what your local tax authority requires and include those details on your invoice.
