E-invoicing for Australia — from ATO Peppol to STP Phase 2.
Australian invoicing sits across three regimes: the ATO-led Peppol BIS Billing 3.0 framework, the quarterly GST and BAS lodgement cycle, and the Single Touch Payroll machinery that runs at every pay event. This centre consolidates eight guides — anchored to ATO, ASIC, ABR Lookup and Treasury practice — on Peppol BIS, ABN/ACN validation, Xero/MYOB/QuickBooks migration, GST at 10%, STP Phase 2, FBT vs PAYG, Trans-Tasman invoicing with New Zealand, and the instant asset write-off.
