How to invoice in Australia

Australia is strict about the heading: the document has to say "Tax invoice" on it. Below that, show your business name, your 11-digit ABN, the issue date, a description of each item, and either the GST amount per line or a statement that the total includes GST. A tax invoice is required for taxable sales over A$82.50 (GST-inclusive), and for invoices of A$1,000 or more you must also show the buyer's identity or ABN. Only businesses registered for GST charge the 10% GST; registration is required once annual turnover reaches A$75,000.

What Australian invoices must include

  • The word “Invoice” and a unique, sequential invoice number
  • The issue date (and the supply date if it differs)
  • Your business name, address and ABN
  • The client's name and address (and their ABN for reverse-charge or intra-EU supplies)
  • A clear description and quantity for each line
  • The net amount per GST rate, the rate(s) applied and the GST amount
  • The total payable, in AUD
  • Payment terms, the due date and how to pay (bank name, IBAN/account)
  • The words "Tax invoice" as the document heading
  • Your 11-digit ABN
  • Buyer's ABN or identity for invoices of A$1,000 or more
  • GST amount per line, or a statement that the total includes GST

GST & reverse charge

For cross-border work, the right wording matters. Invoice Forever offers ready-made Australian GST notes such as:

  • Total includes GST at 10%.
  • GST-free supply — no GST has been charged (e.g. export or other GST-free goods and services).
  • Supplier is not registered for GST; no GST has been charged.

E-invoicing in Australia

E-invoicing is mandatory only in the public sector, not for B2B. From mid-2026 all Non-Corporate Commonwealth Entities must receive at least 30% of their supplier invoices via the Peppol network, and by December 2026 must be able to automatically process incoming invoices and send Peppol e-invoices. Private-sector B2B adoption remains voluntary and government-encouraged, with no compulsory mandate.

Invoice Forever can export a structured EN 16931 / Peppol BIS (UBL) e-invoice alongside the PDF (beta) — the format most of these mandates are built on. You still send it via your own access point, and some countries require their own national format.

Payment terms in Australia

Payment terms are set by agreement; 14 to 30 days from the invoice date is the common B2B norm, and many small businesses invoice on shorter 7- or 14-day terms. Include your BSB and account number (or PayID) so clients can pay by bank transfer.

Questions about invoicing in Australia

GST is 10% on most goods and services. You must register for GST once your annual turnover reaches A$75,000 (A$150,000 for non-profits), and only registered businesses charge GST on their invoices.

Yes. If you are registered for GST, your 11-digit ABN must appear on every tax invoice. If you supply a business without quoting an ABN, the payer may be required to withhold 47% of the payment.

Not for business-to-business. E-invoicing over the Peppol (PINT A-NZ) network is mandatory only for federal government agencies — from mid-2026 at least 30% of their supplier invoices must arrive via Peppol. Private businesses are encouraged but not required to adopt it.
