  • Yes, eInvoicing is becoming mandatory for Australian Government agencies. Currently, eInvoicing applies to federal government entities, many state and local government bodies, and the suppliers that work with them. By 1 July 2026, all Non-Corporate Commonwealth Entities (NCEs) must ensure that at least 30% of the invoices they receive are Peppol eInvoices, and by December 2026 they must be able to automatically process and send eInvoices using the Peppol standard. While a nationwide B2B mandate has not yet been announced, government policy clearly signals broader public-sector adoption and stronger expectations for suppliers to onboard. Businesses that trade with government agencies and those preparing for future national requirements will benefit significantly from adopting eInvoicing early.
