How to Make an Invoice for Free

By Daniel · Updated July 2026

An invoice is simply a clear request for payment: who is billing whom, for what, how much, and by when. Getting those details right is what gets you paid promptly — you do not need accounting software for it.

What every invoice needs

  • Your details and the client's — names, and contact or business details for both sides.
  • An invoice number and date — so both of you can refer to it later.
  • Line items — what you did or supplied, with quantities and prices.
  • The total, and any tax — shown clearly.
  • Payment terms — when it is due and how to pay.

How to make one

  1. Open the invoice generator and fill in your details and your client's.
  2. Add a line for each item or service, with quantity and price — the total adds up for you.
  3. Set the invoice number, date and payment terms, then download the PDF.

Getting paid faster

Clear, early payment terms help more than anything. State the due date plainly, give an easy way to pay, and send the invoice promptly. A tidy, professional-looking document also quietly signals that you expect to be paid on schedule.

The invoice is built in your browser, so your details and your client's are never uploaded to a server.
