How do consultants invoice clients?

Consultants typically bill either by the hour, on a fixed project fee, or via a monthly retainer — and often a mix. List each clearly with the period covered. This tool comes pre-set with an hourly line and a retainer line you can adjust.

What are normal consulting payment terms?

Net 15 to Net 30 is standard. Retainers are usually billed in advance for the upcoming month, while hourly work is billed after it's delivered. Stating this on the invoice avoids confusion.

Should I show my hourly rate on the invoice?

Yes. Showing hours × rate is transparent and makes approval faster, especially for corporate clients whose finance teams need the breakdown.
