If your business supplies goods or services to Australian government agencies, there are two dates in 2026 worth understanding. The first is 1 July 2026. The second is December 2026. Both are tied to Australia’s eInvoicing mandate, and if you’re running MYOB Acumatica, the good news is that you already have what you need to comply. You just need to connect the pieces.
This post covers what eInvoicing actually means in 2026, what’s changed from the earlier Peppol rollout, and how MYOB Acumatica users get set up before the deadlines hit.
What Australia’s eInvoicing mandate requires in 2026
Australia adopted the Peppol eInvoicing standard back in 2019. What’s changed is the teeth behind it. The Australian Taxation Office now requires all Non-Corporate Commonwealth Entities (NCEs), meaning federal government departments and agencies, to receive 30% of their invoices via eInvoicing by 1 July 2026. By December 2026, they must also be able to send eInvoices automatically.
For businesses supplying to government, the practical effect is straightforward: if you’re invoicing a federal agency and you’re not sending via Peppol, there’s a good chance your trading partner will start pushing you in that direction this year. Some agencies are already requiring it for new supplier onboarding.
The technical standard has also tightened. Since 15 May 2025, the only supported format for sending eInvoices in Australia is Peppol PINT A-NZ. The earlier ANZ BIS 3.0 format is no longer valid for sending. If your system was set up on the older format, it needs updating.
How MYOB Acumatica connects to the Peppol network
MYOB Acumatica doesn’t connect to Peppol directly out of the box. You connect through an accredited Peppol Access Point, which is a service provider that sits between your system and the Peppol network and handles the translation and routing.
The most established Access Point for MYOB Acumatica users in Australia is MessageXchange, which holds Peppol certification and maintains a dedicated MYOB Acumatica integration. MessageXchange handles the PINT A-NZ format mapping and can adjust the configuration as standards evolve, without you needing to touch the underlying ERP setup.
Setup is faster than most people expect. According to MessageXchange, connecting to the Peppol network through an Access Point can take less than a day once you have your ABN registered as your Peppol Participant ID. The ABN is how your business is identified on the Australian Peppol network, and it’s the same identifier your trading partners use to route invoices to you.
What changes in your day-to-day invoicing workflow
Once you’re connected, the invoicing workflow in MYOB Acumatica doesn’t change significantly for your team. You create the invoice the same way you always have. The Access Point intercepts the data, converts it to PINT A-NZ format, and delivers it directly into your customer’s accounts payable system through the Peppol network.
The practical differences your team will notice: no more PDFs attached to emails for Peppol-connected customers, faster acknowledgement of receipt, and in many cases faster payment because the invoice arrives pre-structured in the buyer’s system rather than requiring manual keying.
Importantly, a Peppol eInvoice that meets the A-NZ Invoice Specification qualifies as a valid tax invoice under Australian law. You don’t need to add “tax invoice” or “GST invoice” headers. The structured data fields carry the required information. If you want to confirm how this aligns with your current invoicing obligations, the ATO’s tax invoice guidance covers the data requirements in detail.
“Most MYOB Acumatica clients we work with are closer to Peppol-ready than they realise. The platform handles the invoicing data correctly. What they’re usually missing is the Access Point connection and the PINT A-NZ mapping. That’s a configuration project, not a system overhaul.”

What about businesses that don’t supply to government?
The 2026 mandates apply specifically to Non-Corporate Commonwealth Entities as buyers. There’s currently no legal requirement for private-sector businesses to send eInvoices to other private-sector businesses in Australia.
That said, eInvoicing adoption among larger private-sector buyers is growing. The same PINT A-NZ standard works across all trading relationships, and if a major customer asks you to invoice via Peppol in the next 12-24 months, being already connected means you can say yes immediately.
It’s also worth considering the operational side. Accounts payable teams at larger organisations are under pressure to reduce manual processing. Structured eInvoices that arrive directly into their ERP reduce re-keying errors and processing time. Some buyers are starting to prioritise Peppol-capable suppliers as part of their procurement criteria, even where it isn’t mandated.
Payday Super and eInvoicing: two compliance projects landing in 2026
It’s worth noting that eInvoicing isn’t the only compliance change hitting MYOB Acumatica users in 2026. The Payday Super requirement, which links superannuation payments directly to each payroll run rather than quarterly, takes effect from 1 July 2026. If you’re planning a system review ahead of the financial year, both projects make sense to address at the same time.
Our MYOB Acumatica payroll guide for 2026 covers the Payday Super requirements in detail if you want to understand the scope of that change alongside eInvoicing.
Frequently asked questions about MYOB Acumatica eInvoicing
Is eInvoicing mandatory for all Australian businesses in 2026?
Not for private-sector transactions. The current mandate applies to Non-Corporate Commonwealth Entities as buyers, requiring them to process 30% of invoices via eInvoicing by 1 July 2026 and to send eInvoices by December 2026. There is no mandatory requirement for business-to-business eInvoicing in the private sector, though adoption is growing.
What is Peppol PINT A-NZ and why does it matter?
PINT A-NZ (Peppol International A-NZ) is the current mandatory format for eInvoicing in Australia and New Zealand. Since 15 May 2025, it is the only supported format for sending invoices on the Peppol network. If your eInvoicing setup was configured on the earlier ANZ BIS 3.0 format, it needs to be updated before you can send compliant eInvoices.
Do I need a separate system to send Peppol eInvoices from MYOB Acumatica?
You need an accredited Peppol Access Point to connect MYOB Acumatica to the Peppol network. Providers like MessageXchange offer a dedicated MYOB Acumatica integration that handles the format conversion and delivery. You continue using MYOB Acumatica as normal; the Access Point manages the transmission to your trading partner.
How do I register for Peppol eInvoicing in Australia?
You register your ABN as your Peppol Participant ID through your chosen Access Point provider. Once registered, your business appears in the Peppol Directory and trading partners can send eInvoices directly to you. The ATO maintains a register of accredited Peppol Access Point providers if you want to review your options.
