How to create an invoice

A practical guide to creating professional invoices that get paid on time.

A good invoice is clear, complete, and easy to pay. Missing information causes delays — clients hesitate when they cannot verify what they owe or who to pay.

Whether you bill hourly, by project, or on retainer, the structure stays the same: who, what, when, and how much.
