MYOB Acumatica eInvoicing in 2026: Peppol Deadlines, PINT A-NZ and How to Connect

Updated 15 September 2026: the 1 July 2026 milestone and Payday Super are now written as past events, the December 2026 and 1 January 2027 (New Zealand) dates added, the PINT A-NZ retirement dates corrected against the A-NZ Peppol repository, the “not on the ATO’s eInvoicing Ready register” finding added with a link, the meta description (which carried another post’s text) fixed, and the short answer, At a glance block, dates table, structured FAQ and related links added.

MYOB Acumatica connects to the Peppol eInvoicing network through an ATO-accredited access point, not natively: as at 15 September 2026 the platform is not on the ATO’s eInvoicing Ready product register, so the access point converts your invoices to the PINT A-NZ format. The 1 July 2026 federal milestone has passed and the next date is December 2026, when agencies must be able to send eInvoices too.

At a glance

• Who it is for: Australian and New Zealand businesses running MYOB Acumatica (or MYOB Advanced, the same product before the 2024 rename) that invoice government agencies or large buyers who are moving to Peppol eInvoicing.
• Problem it solves: Knowing which eInvoicing dates apply to you, and what it takes to send and receive PINT A-NZ eInvoices from MYOB Acumatica.
• Platforms: MYOB Acumatica, any edition, connected through an ATO-accredited Peppol access point.
• Typical cost: No published figure. The ATO notes access points charge per invoice, per data volume or by subscription, and the amount varies by provider, per its guidance for medium and large businesses. The MYOB Acumatica side is a configuration project scoped with your partner.
• Typical timeline: The network connection is the short part. Onboarding the customers and suppliers you want to exchange eInvoices with takes longer and is paced by them, not by the software.
• Last verified: 15 September 2026 against the ATO’s eInvoicing for government page (updated 5 August 2026), the eInvoicing Ready product register and the A-NZ Peppol specification repository.

If your business supplies goods or services to Australian government agencies, the eInvoicing timetable has moved on since we first wrote this post in March. The first federal milestone has been and gone. The next one is a few months away. And the technical standard underneath it all has finished its changeover. If you run MYOB Acumatica, the good news has not changed: the invoicing data is already in the right shape. What you need is the connection.

This post covers where the mandate stands in September 2026, how MYOB Acumatica eInvoicing actually reaches the Peppol network, and what changes for your accounts team once it does.

What does Australia’s eInvoicing mandate require in 2026?

Australia adopted the Peppol framework in 2019, with the Australian Taxation Office (ATO) as the Australian Peppol Authority. What has changed since is the pressure on government buyers. The ATO’s eInvoicing for government page sets out two transitional targets for Non-corporate Commonwealth Entities (NCEs), meaning federal departments and agencies: 30% of all invoices received as eInvoices by 1 July 2026, and the ability to process and send eInvoices automatically by December 2026. Behind those targets, Treasury and the Department of Finance are establishing eInvoicing as the default method of invoicing in Commonwealth procurement.

The practical effect for suppliers is that agencies now have a number to hit and a quarterly report to the ATO on how they are tracking. The ATO’s own advice to agencies is to prioritise their highest-volume suppliers and to write eInvoicing into new contracts and renewals. If you invoice a federal department and still send PDFs, expect the conversation. The ATO also lists the government entities able to receive eInvoices, which is the quickest way to check whether a specific customer is ready for you.

State governments are further along than most people assume. Per the same ATO page, many Queensland Government agencies can both receive and send eInvoices, most New South Wales agencies can receive them, and more than 300 state, territory and local government organisations are on the network. For a Brisbane business that sells to Queensland Government, eInvoicing is available today, not in December.

New Zealand has gone a step further. Under the fifth edition of the Government Procurement Rules, agencies must ensure large suppliers send eInvoices from 1 January 2027, where a large supplier is one with total revenue above NZ$33 million. If your MYOB Acumatica business trades across the Tasman at that scale, the New Zealand date is the one to plan around.

Does MYOB Acumatica send Peppol eInvoices out of the box?

No. MYOB Acumatica connects to the Peppol network through an accredited access point, a service that sits between your system and the network, converts your invoice data into the Peppol format and routes it to your customer’s own access point. The ATO keeps an eInvoicing Ready product register of software that has demonstrated native send or receive capability; as at 15 September 2026 it lists MYOB Business, but not MYOB Acumatica. That is not a gap in the platform so much as a design choice common to mid-market ERP: the access point handles the network side, and the ERP keeps doing the accounting.

One accredited access point with a published MYOB Acumatica integration is MessageXchange, which supports both Peppol eInvoicing and EDI for the platform and appears on the ATO’s accredited Peppol service provider register. Other accredited providers on that register can connect an ERP through an API or file exchange; the register is the place to compare them, and the ATO publishes a checklist for selecting an access point.

Your Australian Business Number (ABN) is the address on the Peppol network. The access point registers it as your Peppol participant identifier, and trading partners route eInvoices to you by ABN, not by email address. Once you are registered to receive, you appear in the Peppol Directory. The ATO’s advice for medium and large businesses is worth a read before you engage a provider: it covers the questions to answer first, such as whether you need to send, receive or both, and which trading partners to start with.

What is PINT A-NZ and does your setup use it?

PINT A-NZ Billing is the Peppol invoice specification for Australia and New Zealand, published by OpenPeppol. It has been the mandatory specification since 15 May 2025. The earlier A-NZ extension of Peppol BIS Billing 3.0 was deprecated on 22 May 2025 and removed from the Peppol network on 31 March 2026, according to the joint Australian and New Zealand Peppol authorities’ repository. If your business connected before mid-2025, confirm with your access point that your mapping is on PINT A-NZ. Anything still on the old profile cannot send.

This is one of the reasons the access point model suits MYOB Acumatica. The specification gets bi-annual updates, per the ATO’s software developer guidance, and the access point absorbs them. Your MYOB Acumatica configuration does not change when the format does.

How MYOB Acumatica eInvoicing changes day-to-day invoicing

Less than your team will expect. You raise the invoice in MYOB Acumatica the way you do now. The access point picks up the invoice data, converts it to PINT A-NZ and delivers it straight into your customer’s accounts payable system through the network. For customers who are not on Peppol, you keep sending PDFs.

The differences your accounts team will notice are on the receiving end. There is an acknowledgement when the invoice lands, so “we never got it” stops being a reason for late payment. The invoice arrives already structured, so nobody on the buyer’s side re-keys your line items. And for Commonwealth agencies there is a payment rule attached: under the supplier pay on-time policy, agencies that receive eInvoices pay them within five days, and the $1 million contract threshold on that rule was removed from 1 July 2022.

A Peppol eInvoice that meets the A-NZ specification is also a valid tax invoice. The ATO, in its role as Peppol Authority, defines the Australian requirements so that eInvoices support GST and are valid tax invoices; the structured fields carry what a tax invoice needs. The same page makes a point worth passing on to anyone nervous about the ATO seeing their invoices: the ATO does not receive a copy of eInvoices and cannot view their contents. If you want to check what a compliant Australian tax invoice has to show, our tax invoice generator lays out the required fields.

“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.”

Do you need eInvoicing if you don’t sell to government?

Not by law. The 2026 targets apply to non-corporate Commonwealth entities as buyers, and the ATO’s guidance is explicit that eInvoicing is not mandatory for business-to-business trade and does not apply to consumer sales at all. Treasury consulted on a business mandate and a “business eInvoicing right” in 2020 and 2021, and the ATO’s software developer page records that neither has been enacted.

The commercial pressure is a different matter. The ATO’s government page puts more than 400,000 Australian businesses on the Peppol network. Larger private buyers with accounts payable automation are steadily asking suppliers for eInvoices because a structured invoice costs them less to process than a PDF, and the access point you connect for a government customer works for every other Peppol-connected buyer as well. Connecting once means you can say yes the first time a major customer asks, which tends to happen in a contract renewal, with a deadline attached.

Receiving is the other half. If your business processes a lot of supplier invoices, being registered to receive eInvoices means those invoices arrive in MYOB Acumatica as data instead of attachments. That is a real reduction in accounts payable keying for a wholesale or construction business with hundreds of supplier bills a month, and it is the reason the ATO frames eInvoicing to medium and large businesses as an accounts payable project as much as a compliance one.

Payday Super landed on the same day: what else changed on 1 July 2026

eInvoicing was not the only change that hit MYOB Acumatica users on 1 July 2026. Payday Super started on the same date, moving superannuation guarantee payments from a quarterly cycle to one tied to each pay run. If you are reviewing your system this financial year, both changes touch the same finance team and the same partner, and it makes sense to look at them together.

Our MYOB Acumatica payroll guide for 2026 covers what Payday Super changed in the payroll module and what to check now that the first quarter under the new rules is behind you.
