An ABN is a unique 11-digit identifier issued by the Australian Business Register to businesses and organisations operating in Australia.
The Australian Business Number is your business's primary identifier for dealings with other businesses, the ATO and government agencies. Registering for an ABN is free and is required before you can register for GST, claim fuel tax credits or interact with the ATO business portal. Your ABN must be quoted on all invoices, purchase orders and business correspondence. If a supplier does not quote an ABN on their invoice, you may be required to withhold 47% of the payment amount and remit it to the ATO (no ABN withholding). An ABN is also required to operate a business bank account and to access many government grants and programs. While having an ABN does not automatically mean you are registered for GST (that is a separate registration), it is the first step. SortBooks tracks ABN references on supplier invoices in Xero and can flag invoices without valid ABNs that may require withholding.

GST is a broad-based consumption tax applied to most goods and services. Businesses collect GST on sales and claim credits for GST paid on purchases, remitting the net amount to the tax authority.
The ATO is Australia's principal tax collection agency, responsible for administering income tax, GST, superannuation, excise and other federal tax obligations.
A tax invoice is a document that includes GST/VAT information and your registration number. It is required for customers to claim input tax credits on their purchases from you.
A sole trader is a business structure where one person owns and operates the business. The owner and the business are the same legal entity, and the owner is personally liable for all debts.
