Freelance Invoice Basics

What solo contractors should include on a professional invoice.

Your invoice is often the last impression before payment. Clarity beats creativity — finance teams approve documents they can understand in ten seconds.

  • —Freelance invoices should read clearly to non-technical AP staff.
  • —Payment terms and due date are not optional.
  • —Professional layout reduces payment delays.

Minimum viable invoice

Include your name or business name, client name, invoice number, dates, line items, total, currency, and how to pay. That alone beats a vague email asking for payment.

  • Your legal name and contact
  • Client company and contact
  • Invoice number and dates

Payment terms for freelancers

Net 15 or Net 30 are common for retainer and project work. Use due on receipt for deposits or small jobs. Put the terms on the invoice and in your contract.

  • Net 15 or Net 30 for projects
  • Due on receipt for deposits
  • Match contract and invoice

Look professional without heavy software
