Register an ABN/ACN.
In Australia, it is a legal requirement for a business owner to register an Australian Business Number (ABN) with the Australian Business Register (ABR). If you are registering a company, you will also need an Australian Company Number (ACN). An ABN is an 11-digit number unique to an enterprise or business. The number is used to identify a business when they’re dealing with the government, other businesses, and the public.
You’ll also need one if you want to register a business name, a website domain or use digital services like eInvoicing. It’s free, and pretty easy to do so.
