How to Invoice as a Sole Trader in Australia

As an Australian sole trader, you invoice clients under your own name (or a registered trading name) with your ABN. If your annual turnover is $75,000 or more you must register for GST and issue tax invoices — otherwise standard invoices are fine.

Step by step:

  • Apply for an ABN through ABR if you don't have one yet — it's free
  • If you expect to earn over $75,000/year, also register for GST
  • Use an invoice template that includes your name, ABN, and contact details
  • Issue a unique sequential invoice number on every invoice
  • List the client's name, the work performed, hours or units, and rate
  • Show subtotal, GST (if registered) and total amount due
  • Set payment terms — Net 7 or Net 14 is common for sole traders
  • Include bank, BPAY, or PayID details for fast payment
  • Send the PDF by email and follow up if not paid by the due date
  • Keep copies of every invoice for at least five years

Without an ABN, clients may withhold 47% under the No-ABN Withholding rule. InvoiceSonic is built for Australian sole traders and pre-fills your ABN and GST settings automatically.
