Electronic invoicing (e-invoicing) is rapidly transforming the way businesses transact. In Australia, one of the key frameworks enabling this change is PEPPOL — a secure, standardized network that allows structured invoice data to be exchanged between organizations. For business-to-government (B2G) transactions, PEPPOL e-invoicing is not just a “nice-to-have” but an increasingly mainstream mechanism. This blog explores what PEPPOL B2G invoicing is, how it’s implemented in Australia, what the future holds (especially looking ahead to 2026), and why choosing the right service provider (like AAssureComply) matters.
Understanding PEPPOL forms the basis of modern e-Invoicing.
PEPPOL means Pan-European Public Procurement Online. It started that way but now serves as a global network in Europe, Asia, Australia, and New Zealand. Organizations exchange invoices as structured data through PEPPOL instead of emailing them. This setup ensures interoperability, security, automation, faster processing, and error reduction.
PEPPOL relies on standardized XML documents rather than PDFs. These documents go through accredited Peppol Access Points. Those act as secure gateways transmitting invoices between systems. Australia started using PEPPOL in 2019. The country now sees it as the main framework for e-invoicing, particularly for Business-to-Government suppliers.
PEPPOL e-Invoicing in Australia shows solid progress today.
The Australian Taxation Office drives this as the Australian Peppol Authority. Key milestones mark the path forward. In 2022, all Non-Corporate Commonwealth Government agencies had to receive PEPPOL e-invoices. From 2024 to 2025, the shift happens to the new PINT A-NZ e-invoicing format. That replaces the older BIS standard.
By 2026, strong adoption targets hit the public sector. Agencies must use e-invoicing in all procurement processes. These updates make e-invoicing the required way to send invoices to the federal government starting in 2026. It stops being just an option.
B2G invoices mean Business-to-Government transactions.
A PEPPOL B2G Invoicing comes from a business to any government body. That includes federal departments, state government agencies, local councils, and government-owned corporations. In the past, suppliers sent these as PDFs via email to procurement departments. PEPPOL changes them into structured e-invoices now.
This transformation brings automatic validation, faster approval, more secure delivery, prompt payments, and full audit trails. Suppliers benefit from fewer rejections and better ties with public sector clients. Things run smoother overall.
Transitioning to PINT A-NZ marks Australia’s new required format for e-invoices.
Australia and New Zealand follow the PINT A-NZ specification, known as Peppol International. It becomes mandatory soon. The shift improves alignment with global standards. It adds more support for invoice types and enhanced data fields.
Interoperability gets better too. Validation rules turn cleaner. Businesses need their invoicing systems to handle PINT A-NZ. They cannot stick with the old BIS 3.0 format. AAssureComply helps fully with migrating to this setup. Your invoices stay accepted without issues.
The PEPPOL Service Provider Register plays a key role in the process.
To send or receive e-invoices, connections go through an accredited PEPPOL Service Provider. People call these Access Points too. The ATO keeps the Peppol service provider register up to date. It lists all certified providers meeting the standards.
These providers handle secure data transmission, correct PEPPOL formatting, compliance with Australian rules, and reliable system connections. Picking the right one matters a lot. Mandates keep growing in the public and private sectors. It affects everyone involved.
Government mandates outline Australia’s 2026 e-Invoicing roadmap clearly
The goal stays straightforward. E-invoicing became standard in the public sector before long. By July 2026, at least 30 percent of invoices to federal agencies must arrive as PEPPOL e-invoices. By December 2026, all agencies handle sending, receiving, and processing e-invoices automatically.
Paper and PDF methods drop off significantly or disappear entirely. Suppliers dealing with government entities need to enable PEPPOL well ahead of 2026. Preparation makes sense now.
Businesses gain real reasons to adopt PEPPOL right away.
Mandates focus on the government for now. Still, benefits reach suppliers directly. Faster payments come first. Structured invoices cut validation time. Government agencies pay quicker as a result.
Costs drop too. E-invoicing cuts manual tasks and saves businesses 60 to 70 percent in processing expenses. Errors decrease with automated validation. That leads to fewer rejected invoices. Fraud risks fall since transmitted invoices resist tampering or faking.
Compliance stays future-proof. As rules spread to B2B areas, early users align completely. They stay ahead of the curve.
