E-invoicing in MYOB Acumatica: Peppol, Setup and What the ATO Expects in 2026

Updated 20 October 2026: added a plain answer on whether MYOB e-invoicing uses Peppol, the identifiers you need (ABN under the 0151 scheme) and a numbered setup sequence for MYOB Acumatica; every date and register entry re-checked against the ATO, the A-NZ Peppol repository and MYOB’s release notes.

Yes. MYOB Acumatica e-invoicing uses the Peppol network, but through an ATO-accredited access point rather than a built-in feature: as at 20 October 2026 the ATO’s eInvoicing Ready register lists MYOB Business, not MYOB Acumatica. Your ABN becomes your Peppol address, the access point converts invoices to PINT A-NZ, and the next government deadline is December 2026, when Commonwealth agencies must send eInvoices too.

At a glance

• Who it is for: Australian and New Zealand businesses on MYOB Acumatica (MYOB Advanced until the 2024 rename) that invoice government agencies or large buyers moving to Peppol eInvoicing.
• Problem it solves: Knowing which eInvoicing dates apply to you, which identifiers the network needs, and how MYOB Acumatica sends and receives PINT A-NZ eInvoices.
• Platforms: MYOB Acumatica, any edition, through an ATO-accredited Peppol access point. MYOB Business has native send and receive.
• Typical cost: No published figure for the connection; the ATO says access points charge per invoice, per data volume or by subscription, per its guidance for medium and large businesses. MYOB Acumatica licensing is quoted per named user through partners; our MYOB Acumatica cost guide covers implementation ranges.
• Typical timeline: The network connection is the short part. Onboarding the customers and suppliers you exchange eInvoices with takes longer and is paced by them.
• Last verified: 20 October 2026 against the ATO’s eInvoicing for government page (updated 13 October 2026), the eInvoicing Ready product register, the ATO’s Peppol identifier page and the A-NZ Peppol repository.

If you supply Australian government agencies, the eInvoicing timetable has moved on since we first wrote this post in March: the first federal milestone has passed and the next is weeks away. On MYOB Acumatica, the invoicing data is already in the right shape. What you need is the connection, and the identifiers that let the network find you.

Does MYOB e-invoicing use Peppol?

Yes, for every MYOB product, but the route differs. Australia runs eInvoicing on the Peppol network with the Australian Taxation Office (ATO) as the Australian Peppol Authority. The question is whether your software talks to the network itself or a service provider does.

MYOB Business does it natively. The ATO’s eInvoicing Ready product register, checked 20 October 2026, lists “MYOB Business - ALL browser products” with send and receive capability.

MYOB Acumatica is not on that register, and neither is MYOB Advanced, the same product under its pre-2024 name. We also searched MYOB’s 2026.1.x release notes, the 2026 R1 notes and the 2025 R2 notes on 20 October 2026 and found no Peppol or eInvoicing entry. So MYOB Acumatica connects through an accredited access point: a service between your system and the network that converts your invoice data to the Peppol format and routes it to your customer’s access point. The ATO’s getting started page lists this as one of four connection routes: “connect existing software to an accredited access point”.

Mid-market ERPs commonly work this way: the access point handles the network and the ERP does the accounting. One accredited provider with a published MYOB Acumatica integration is MessageXchange, which supports Peppol eInvoicing and EDI and is on the ATO’s accredited service provider register of around 50 providers. The ATO also publishes a checklist for selecting an access point with 13 things to ask.

What does Australia’s eInvoicing mandate require in 2026?

Australia adopted Peppol in 2019; what has changed since is the pressure on government buyers. The ATO’s eInvoicing for government page, updated 13 October 2026, sets 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 automated processing and sending of eInvoices by December 2026. Agencies report progress quarterly, and from July 2026 that report includes eInvoices sent.

Agencies now have a number to hit and a quarterly report on it. If you invoice a federal department and still send PDFs, expect the conversation. The ATO lists the government entities able to receive eInvoices with their ABNs, the quickest way to check a specific customer.

State governments are further along than most people assume. Per the same ATO page, many Queensland Government agencies can both receive and send eInvoices, all New South Wales Government agencies can receive them, and more than 300 state, territory and local government organisations use eInvoicing. For a Brisbane business selling to Queensland Government, that means now.

New Zealand has gone further. Under the fifth edition of the Government Procurement Rules, agencies must ensure large suppliers send eInvoices from 1 January 2027, a large supplier being one with total revenue above $33 million. If you trade across the Tasman at that scale, plan around that date.

What identifiers do you need to set up e-invoicing?

Your ABN, as a Peppol participant identifier. Every entity in the Peppol Directory has a participant identifier made of a scheme, an International Code Designator (ICD) and the identifier itself. The ATO’s page on identifying Australian entities on the network gives its own as the worked example, “iso6523-actorid-upis::0151:51824753556”, and states that “‘0151’ is the ICD for the ABN which is used by most Australian businesses”. Your Peppol address is 0151 followed by your ABN. New Zealand businesses use their NZBN. Some groups that trade overseas use a different ICD; settle that before registration.

An access point registration. The access point registers your participant identifier and, once you can receive, lists you in the Peppol Directory: “When you can receive eInvoices, your service provider will list you in the Peppol Directory”, as the ATO puts it. Only receivers are published, so a send-only business may not appear at all. If a customer cannot find you in the directory, that is usually why.

Your trading partners’ ABNs in your invoice data. The ATO says the ABN “is the business identifier that is commonly used to route eInvoices in Australia” and that your system should include both your ABN and your receiver’s ABN. An invoice to a customer record with no ABN has nowhere to go, so run your customer master through an ABN check before you connect.

What does the ATO expect a business to have in place?

The ATO does not certify individual businesses, but its getting started guidance, updated 3 September 2026, defines the end state: “A business is eInvoice-enabled when they can send and receive eInvoices through the Peppol network”, and “you will need software to receive or send the invoice data and an accredited access point to connect to the Peppol network”.

So the ATO expects you to have decided your scope (send, receive or both), chosen a connection route and an accredited access point, and picked the trading partners to start with, ideally a few with simple requirements and high volumes. There is no form to lodge with the ATO. As Peppol Authority, the ATO does not receive a copy of eInvoices and cannot view their contents.

How do you set up MYOB Acumatica for eInvoicing through an access point?

MYOB documents no native eInvoicing screen in MYOB Acumatica, so the setup is the provider’s connector plus the ERP data it reads. Here is the sequence we scope with clients.

1. Decide send, receive or both, and list the first partners. A Commonwealth agency you already invoice is the obvious first receiver: it is on the ATO’s enabled entities list and has a target to meet.
2. Choose an accredited access point with a MYOB Acumatica connector. Work from the ATO’s register and checklist. Ask how the connector reaches MYOB Acumatica (API, SFTP or file export), who maintains the PINT A-NZ mapping when the specification changes, and what happens when a message bounces. If the connector uses the MYOB Acumatica API, confirm your licence covers it; our hidden costs guide covers that line item.
3. Register your ABN as the participant identifier. The access point registers 0151 plus your ABN and lists you in the Peppol Directory once receiving is on. If you run several companies in one tenant, each ABN is its own participant, so decide which entities register.
4. Prepare the ERP side. ABNs on every customer and supplier record you will exchange eInvoices with, GST tax codes the connector can map to the specification’s tax categories, and the document mapping that takes your MYOB Acumatica invoice fields (both ABNs, invoice number and date, lines, GST per line, totals, payment details) into PINT A-NZ. The connector handles the format; someone still has to check the data.
5. Test with one receiver. Send a live invoice to one agency or willing customer and confirm the acknowledgement comes back. If you receive, confirm a supplier’s eInvoice lands as a bill with lines populated.
6. Onboard the rest. Write eInvoicing into new contracts and renewals and work through your customer list by volume. This step is paced by your trading partners.

None of this is customisation, which is why it fits inside a fixed-scope piece of work rather than a development project.

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 and mandatory 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 as of 31 March 2026, per the joint Peppol authorities’ repository. If you 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 reason the access point model suits MYOB Acumatica. The specification gets bi-annual releases, 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 as you do now; the access point picks up the data, converts it to PINT A-NZ and delivers it into your customer’s accounts payable system. For customers not on Peppol, you keep sending PDFs.

The differences show up on the receiving end. There is an acknowledgement when the invoice lands, so “we never got it” stops being a reason for late payment, and nobody on the buyer’s side re-keys your lines. For Commonwealth agencies there is a payment rule too: under the supplier pay on-time policy, agencies that receive eInvoices pay them within five days regardless of value, the $1 million threshold having been removed from 1 July 2022.

A Peppol eInvoice that meets the A-NZ specification is also a valid tax invoice: the ATO, as Peppol Authority, defines the Australian requirements so that the specification supports GST and eInvoices are valid tax invoices. 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, the ABN on half their customer records 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 bind Commonwealth entities as buyers; eInvoicing is not mandatory for business-to-business trade. Treasury consulted on mandatory business adoption in November 2020 and a Business eInvoicing Right in December 2021, and the ATO’s software developer page records that neither has been enacted.

The commercial pressure is a different matter. The ATO’s enabled entities page describes the Peppol Directory as holding hundreds of government organisations and thousands of other Australian businesses that can receive eInvoices. Larger private buyers ask for eInvoices because a structured invoice costs them less to process than a PDF, and the connection you build for one government customer works for every other Peppol buyer, so you can say yes the first time a major customer asks, usually in a contract renewal with a deadline attached.

Receiving is the other half. Registered to receive, your supplier invoices arrive in MYOB Acumatica as data instead of attachments, a real cut in keying for a wholesaler or builder with hundreds of supplier bills a month.

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

Payday Super started the same day, moving superannuation guarantee payments from a quarterly cycle to each pay run. Both changes touch the same finance team. Our Payday Super checklist for MYOB Acumatica payroll covers what to reconcile now that the first quarter under the new rules is behind you.

Goes well with

• MYOB Acumatica accounts payable: vendor bills, EFT payments and BAS-ready coding: where received eInvoices land and how the bill gets matched and paid.
• MYOB Acumatica accounts receivable: invoices, dunning letters and getting paid on time: the module your eInvoices come out of.
• MYOB Acumatica support: what’s included and what costs extra: where a connection project sits against your support arrangement.
