Procurement, vendor and AP software in Australia
Australia is one of the few markets where e-invoicing is already normal in government supply chains, and where large companies publish how fast they pay suppliers. Both facts change what a good procurement or AP tool needs to do.
The short answer
Australian companies buying procurement, purchase order, vendor management or AP software should test four things: ABN validation at supplier onboarding, Peppol e-invoice sending and receiving, payment data that supports Payment Times Reporting and the Taxable Payments Annual Report where they apply, and a two-way sync with Xero, MYOB, NetSuite, Dynamics 365 or TechnologyOne. GST is 10% and most businesses close their year on 30 June.
Four guides, each built around how Australians search
Australian search volumes are healthy for a market this size. 'AP automation' and 'vendor management system' lead their categories, and each guide uses the local phrasing.

Australia took e-invoicing seriously early. Non-corporate Commonwealth entities have had to receive Peppol e-invoices since July 2022 and aim to pay valid ones within five days. The proposed Business e-Invoicing Right, which would have let any business demand Peppol invoices from suppliers, was not enacted, so B2B adoption is voluntary. Even so, Peppol is a normal question in Australian tenders, and AP tools are expected to handle it.
Payment speed is public here. Under the Payment Times Reporting scheme, large businesses report how quickly they pay small business suppliers, and the data is published. That gives AP teams a board-level reason to fix slow approvals, and it means the AP system needs clean data on invoice receipt and payment dates.
Supplier identity runs through the ABN. Businesses check a supplier's ABN through ABN Lookup at onboarding, and if a supplier does not quote one, the payer may have to withhold tax from the payment. Add the Taxable Payments Annual Report for contractors in industries like construction, cleaning, courier and IT, and the supplier master becomes a tax record in its own right.

Compliance timeline
July 2022
Non-corporate Commonwealth entities must be able to receive Peppol e-invoices.
1 July 2026
Target for those entities to process at least 30% of received invoices via Peppol.
Each reporting period
Large businesses file under the Payment Times Reporting scheme.
Where Australian teams feel it first
Building and construction
Contractor payments must be reported in the Taxable Payments Annual Report, and subcontractor insurance and licences expire constantly. Vendor management and AP have to share one supplier record.
Government suppliers
Suppliers to Commonwealth agencies get paid faster on Peppol e-invoices. They are usually the first Australian businesses to send e-invoices themselves.
Mining and resources
Remote sites, capital purchases and long supply chains make PO control and goods receipt the priority. Western Australian operators often run TechnologyOne or SAP.
Health and aged care
Large provider groups buy from thousands of suppliers and handle sensitive data. Supplier risk, privacy and contract tracking come before AP speed.
Buying software in Australia: FAQ
Not for business-to-business invoices. Non-corporate Commonwealth entities must be able to receive Peppol e-invoices, and the proposed Business e-Invoicing Right was not enacted, so B2B use remains voluntary.
A scheme that requires large businesses, generally those with total income above AUD 100 million, to report how they pay small business suppliers. Reports are published by the Payment Times Reporting Regulator.
You should. If a supplier does not quote a valid ABN, you may need to withhold tax from payments. Most vendor management and AP tools check ABNs automatically against ABN Lookup.
Xero and MYOB dominate small and mid-sized businesses. Larger companies run NetSuite, Dynamics 365, TechnologyOne and SAP.
Many Australian businesses close their year on 30 June. Starting an evaluation in the first quarter of the calendar year gives you time to go live before the new financial year.
