The anatomy of an invoice

  • Header — the word "Invoice" (or "Tax Invoice"), your logo and a unique invoice number
  • Your details — business name, ABN, address and contact info
  • Client details — who the invoice is billed to
  • Dates — the issue date and the payment due date
  • Line items — a description, quantity, unit price and amount for each
  • Totals — subtotal, GST (if any) and the total due
  • Payment details — how and when to pay (bank/BSB or payment link)

What a tax invoice looks like (Australia)

A tax invoice looks much like a regular invoice, with a few required additions: the words "Tax Invoice", your ABN, and the GST amount shown clearly (or a statement that the total includes GST). For sales over $1,000 it must also show the buyer's identity or ABN.

FAQ

What's the difference between an invoice and a tax invoice?

A tax invoice is issued by a GST-registered business and must show the words "Tax Invoice", your ABN and the GST amount. A regular invoice has no GST and isn't labelled "Tax Invoice".

Does an invoice need a logo?

No — a logo is optional. What matters are the required fields: your business name and ABN, the client, dates, line items, totals and payment details. A logo just makes it look more professional.

What should a simple invoice include?

At minimum: the word "Invoice", a unique number, your business name and ABN, the client's details, the date, a description of what you supplied, the total, and how to pay.
