Why Professional Invoices Matter
A professional invoice does more than request payment — it establishes trust, sets clear payment terms, and creates a paper trail for taxes. Research shows freelancers who use professional invoices get paid an average of 11 days faster than those using informal requests.

- Invoice number — Sequential, unique identifier for your records
- Issue date and due date — Typically Net 15, Net 30, or Net 60

Invoice — Sent after work is complete (or at milestones). Requests payment. Legally binding when accepted.
Receipt — Confirmation that payment was received. Issued after payment.
