PDF Invoice Template

A PDF invoice template is the format you should actually send in: it cannot be edited by the recipient, it looks identical on every device, and every accounts system in the world can open it. Fill in the fields below and download one instantly.

Typical line items

Fields you'll usually include on this invoice:

  • Business and client details, with your tax or EIN number
  • Invoice number and issue date
  • Line items with quantity, rate and amount
  • Subtotal, sales tax and total due
  • Due date and payment instructions

Invoicing Tips

  • PDF is a sending format, not an editing format. Build the invoice somewhere that calculates, then export — do not try to edit a PDF each month
  • It cannot be altered by the recipient, which is the entire reason payment records are sent this way
  • It renders identically everywhere. Word and Excel files reflow on a different machine and can arrive looking broken
  • Name the file with the invoice number, not invoice-final-v2. The client accounts team files by reference
  • Keep the PDF as your record copy — it is the version the client actually received

Common Mistakes to Avoid

  • Sending an editable .docx or .xlsx to a client instead of a PDF
  • Exporting an image of an invoice rather than a real PDF, so text cannot be selected or searched
  • Filing PDFs under names that do not include the invoice number
  • Trying to hand-edit last month PDF instead of regenerating it

Frequently Asked Questions

Why send invoices as PDF?

Because a PDF cannot be edited by the recipient, renders identically on every device, and can be opened by any accounts system. A Word or Excel invoice can be altered and may reflow into something unreadable on another machine.

How do I make a PDF invoice for free?

Fill in the fields on this page and download it — no signup, no watermark. The totals and tax calculate as you type, which is the part that hand-built PDF invoices get wrong.

Can I edit a PDF invoice after sending it?

You should not. If something is wrong, issue a corrected invoice with a new number, or a credit note against the original. Editing a sent invoice breaks the audit trail on both sides.
