Australian invoicing tips for small businesses
Tax invoice requirements
If you are registered for GST, your invoices for $1,000+ must include: the words "Tax Invoice", your ABN, the date, a description of goods/services, the GST amount, and the total including GST.
Set clear payment terms
Always state your payment terms clearly on every invoice. Net 7 or Net 14 days is standard for most Australian small businesses. The longer you give clients to pay, the longer you wait for your money.
Use sequential invoice numbers
Number your invoices sequentially (INV-001, INV-002 etc). The ATO requires you to keep records of all invoices issued. Sequential numbering makes your bookkeeping and tax time much simpler.
Do you need to charge GST?
You must register for GST and charge 10% GST if your annual turnover is $75,000 or more. Below this threshold, GST registration is optional. If not registered, do not include GST on your invoices.
Follow up promptly
Send a polite reminder the day payment is due, then follow up at 7 and 14 days overdue. Most late payments in Australia are due to oversight rather than intent — a friendly reminder usually works.
Keep records for 5 years
The ATO requires you to keep business records including invoices for 5 years. Save your PDFs in a cloud folder (Google Drive, Dropbox) organised by financial year so they are easy to find at tax time.
