Key takeaways

• Non-corporate Commonwealth entities (NCEs) have had to receive Peppol e-invoices since 1 July 2022, with a 1 July 2026 milestone of 30% e-invoices received. Business-to-business (B2B) e-invoicing remains voluntary but is growing fast.
• A 2025 study by Avalara and the Centre for Economics and Business Research (Cebr) found e-invoicing saves approximately 39 minutes per invoice in processing time. It also shortens payment cycles by 1.4 days on average across the six markets studied, including Australia, freeing you and your clients to focus on advisory work.
• Australia uses the Peppol network with the Peppol International (PINT) A-NZ specification, and the Australian Taxation Office (ATO) is the Australian Peppol Authority. Setting up is straightforward through an accredited Access Point.
• Even where e-invoicing isn't yet mandatory for your clients, adopting it now positions your practice ahead of future requirements, and research by Avalara and Cebr estimates full adoption could deliver economy-wide gains of up to A$22.5 billion a year for Australia.

Why e-invoicing matters for Australian practices

E-invoicing is reshaping how Australian practices handle invoice processing, compliance, and client advisory. With the federal government already mandating e-invoicing for its own agencies and setting ambitious adoption targets, understanding the practical implications for your practice and clients is essential.

Faster, more accurate invoicing matters for clients waiting on payment. According to Xero Small Business Insights, Australian small businesses were paid 6.9 days late on average in the September quarter of 2026. For your practice, structured e-invoices also mean less manual processing. When supplier invoices arrive directly in your clients' accounting software with all transaction data pre-populated, the time you spend on data entry, reconciliation, and chasing missing details drops substantially.

For your practice, this shift has two dimensions. On the practice side, e-invoicing reduces the time you spend on invoice processing and data entry for clients. Instead of manually entering supplier invoices into each client's accounting system, the data arrives pre-populated and accurate. On the advisory side, it opens a genuine opportunity to guide clients through adoption, helping them streamline their accounts payable and receivable processes before any B2B mandate arrives.

The ATO is actively encouraging voluntary adoption, and businesses that start now will be better prepared as regulatory requirements expand. Your role as a trusted adviser makes you the natural starting point for clients looking to make this transition.

E-invoicing also opens up cross-border opportunities. The Peppol network connects businesses across Australia, New Zealand, Singapore, and parts of Europe, so clients with international trading relationships can send and receive standardised invoices without additional complexity. For practices with clients who import or export goods and services, this is a practical advantage worth highlighting.

How e-invoicing works in Australia

Australia's e-invoicing framework is built on the Peppol network, an open, secure international standard used across Europe, New Zealand, Singapore, and other regions. The following outlines how the system operates in the Australian context.

The ATO is the designated Peppol Authority in Australia, overseeing the network's operation and accrediting Access Points. These Access Points act as intermediaries that connect your clients' accounting software to the Peppol network, similar to how an internet service provider connects you to the web.

Australia uses the PINT A-NZ specification as its mandatory e-invoice format. This specification standardises the data structure of invoices so they can be exchanged reliably between different accounting systems. The transition to PINT A-NZ was completed on 15 May 2025, replacing earlier formats.

The e-invoicing process works in four stages.

1. The sender creates an invoice in their accounting software, just as they would normally. The software formats it according to the PINT A-NZ specification automatically.
2. The invoice is transmitted through the sender's Access Point to the Peppol network, which routes it to the recipient's Access Point.
3. The recipient's accounting software receives the invoice directly, with all transaction data populated. In Xero's e-invoicing software, the e-invoice appears as a draft bill ready for review and approval.
4. Secure transmission between tracked Peppol access points creates a clear audit trail that supports compliance and reduces fraud risk.

Both sender and recipient need to be connected to the Peppol network, but they don't need to use the same accounting software. As long as both parties have an accredited Access Point, e-invoices flow between systems without re-keying.

E-invoicing requirements and mandates

Australia's e-invoicing requirements are evolving, with government agencies leading the way and broader mandates likely to follow. Understanding the current landscape helps you prepare clients and position your practice for what's ahead.

Australian government mandates

The federal government has been rolling out e-invoicing requirements in phases. Non-corporate Commonwealth entities (NCEs) have been required to receive Peppol e-invoices since 1 July 2022. The government has set further targets to deepen adoption across its operations, as outlined in the ATO's e-invoicing guidance for government.

• The government's 1 July 2026 milestone asked NCEs to work with suppliers so that 30% of the invoices they receive are e-invoices. Entities report their progress to the Australian Peppol Authority every quarter.
• By December 2026, NCEs must be able to send e-invoices and process them automatically.
• E-invoices that meet the A-NZ Invoice Specification qualify as valid tax invoices under Australian tax law, without needing the "tax invoice" label.
• Standard five-year record retention requirements apply to e-invoices, just as they do to other tax records.

B2B e-invoicing in Australia

Business-to-business e-invoicing in Australia is currently voluntary. However, the government's strong push on government-to-business adoption signals that B2B mandates could follow. The pattern is clear from international precedents: countries typically start with business-to-government (B2G) mandates before expanding to B2B, as Belgium, Italy, and others have done.

Encouraging your clients to adopt e-invoicing now means they'll already have systems and processes in place when requirements change. It also positions your practice to offer a proactive advisory service well before any mandates arrive. Commonwealth agencies have been asked to work with suppliers to lift e-invoicing volumes, so clients who trade with them are a natural entry point for broader adoption.

Global context

Australia's approach sits within a broader global trend. Understanding what other countries are doing gives you useful context when advising clients with international operations.

• Brazil and Mexico have had comprehensive e-invoicing mandates in place for years, covering both B2G and B2B transactions
• Belgium introduced mandatory B2B e-invoicing from 1 January 2026, joining a growing list of European countries requiring electronic invoicing between businesses
• Singapore, New Zealand, and Malaysia also use the Peppol network, making cross-border e-invoicing straightforward for clients trading in the Asia-Pacific region
• The European Union continues to expand e-invoicing requirements, with many member states implementing or planning B2B mandates

3 benefits of e-invoicing for accountants and bookkeepers

The practical advantages of e-invoicing go well beyond compliance. For your practice and your clients, the efficiency gains are measurable and meaningful.

1. Cut invoice processing time

E-invoicing saves approximately 39 minutes per invoice in processing time, according to Avalara and Cebr research across six markets, including Australia. That time adds up quickly across a client base. Instead of downloading PDFs from emails, re-keying data into accounting software, and chasing missing details, the invoice data arrives in the right system automatically.

For your practice, this means less time spent on repetitive data entry and more capacity for advisory work. Consider a client who processes 200 supplier invoices per month: at 39 minutes saved per invoice, that's about 130 hours per month freed up for higher-value tasks. For your clients, it means their accounts payable teams can process invoices faster with fewer errors, reducing the back-and-forth that slows down payments.

The structured data format also means fewer invoice queries. Because e-invoices include standardised fields that the recipient's software can read automatically, issues like missing purchase order numbers or incorrect line items are caught before the invoice is sent.

2. Shorten payment cycles

E-invoicing shortens payment cycles by 1.4 days on average across the six markets in the Avalara and Cebr research. Australian firms using it are paid up to 2.5 days sooner. When invoices arrive instantly in the recipient's accounting software with all details pre-populated, there's no delay from manual processing. Your clients' customers can review and approve invoices faster, which supports healthier cash flow.

Avalara and Cebr estimate full e-invoicing adoption could deliver up to A$22.5 billion a year in economic gains for Australia, driven by higher productivity and faster payments. Reduced fraud adds to the benefit. For your clients, even small improvements in payment timing can ease pressure on working capital.

3. Strengthen compliance and reduce risk

E-invoices use structured data and secure transmission between tracked Peppol access points, creating a detailed audit trail. Research by Avalara and Cebr found e-invoicing cuts invoice fraud and lost invoices by around 30–40 percent. For practices managing compliance across multiple clients, this level of data integrity is valuable.

E-invoices that meet the A-NZ Invoice Specification automatically qualify as valid tax invoices, simplifying Goods and Services Tax (GST) compliance for your clients. The digital audit trail also makes it easier to respond to ATO queries and support clients during reviews.

From a practice management perspective, e-invoicing also reduces your professional risk. When invoice data is transmitted electronically between verified systems, there's less chance of manual errors that could lead to incorrect Business Activity Statement (BAS) reporting or GST discrepancies. The audit trail is clear, verifiable, and stored digitally, which supports your record-keeping obligations under Australian tax law's five-year retention requirement.

How to set up e-invoicing for your practice and clients

Getting started with e-invoicing is more straightforward than many practices expect. Follow these steps to set it up for your practice, then roll it out to clients.

1. Connect to the Peppol network through an Access Point

To send and receive e-invoices, you need to connect to the Peppol network through an ATO-accredited Access Point. Access Points are service providers that handle the technical connection between your accounting software and the Peppol network. Some accounting software providers, including Xero, have built-in Access Point capabilities, so you may not need a separate provider.

2. Register for a Peppol Participant ID

Each business on the Peppol network needs a unique Peppol Participant ID, which is typically based on the Australian Business Number (ABN). Your Access Point provider will help you register. Once registered, other Peppol participants can send e-invoices directly to your accounting software using this identifier.

3. Enable e-invoicing in your accounting software

If you're using Xero, enabling e-invoicing is built into the platform. You can register with the Peppol network from within Xero using the ABN in your organisation settings, and Xero handles the PINT A-NZ formatting automatically. Everything runs inside the Xero platform you already use. Once enabled, incoming e-invoices appear as draft bills ready for your review.

4. Roll out to clients

Once your practice is set up, you can guide clients through the same process. This is a genuine advisory opportunity: helping clients connect to the Peppol network, register their Participant IDs, and configure their software gets them exchanging e-invoices sooner and makes you their go-to adviser for digital transformation.

Start with clients who have high invoice volumes or trade with government agencies, where the benefits are most immediate. Commonwealth agencies have a target of receiving 30% of their invoices as e-invoices, so clients who supply them have the strongest incentive to get set up. From there, you can expand to clients who would benefit from faster payment cycles or reduced processing costs, building e-invoicing adoption into your standard onboarding and advisory conversations.

FAQs on e-invoicing for accountants

Here are some frequently asked questions you might ask about e-invoicing as an Australian accountant or bookkeeper.

Is e-invoicing mandatory in Australia?

E-invoicing is mandatory for Commonwealth government agencies, which have been required to receive Peppol e-invoices since 1 July 2022. For business-to-business transactions, e-invoicing is currently voluntary. However, government adoption targets and global trends suggest B2B mandates may follow.

What is a Peppol Access Point?

A Peppol Access Point is a service provider accredited by the ATO that connects your accounting software to the Peppol e-invoicing network. It handles the technical exchange of e-invoices between sender and recipient. Some accounting platforms, including Xero, have built-in Access Point functionality.

Can your clients use e-invoicing if their suppliers use different accounting software?

Yes. The Peppol network is designed to work across different accounting systems. As long as both parties are connected to the network through an accredited Access Point, e-invoices can be exchanged regardless of which software each business uses. The PINT A-NZ specification ensures the data format is standardised.

How do you register your clients for e-invoicing?

Each client needs a Peppol Participant ID, which is typically based on their ABN. You can register them through their Access Point provider or directly through compatible accounting software. In Xero, setup is built into the platform: you register with Peppol using the ABN in the client's organisation settings.

Do e-invoices qualify as tax invoices under Australian law?

Yes. E-invoices that meet the A-NZ Invoice Specification are recognised as valid tax invoices under Australian tax law. They don't need to include the words "tax invoice" separately. Standard five-year record retention requirements apply, just as they do for traditional invoices.

How does e-invoicing improve security compared to traditional invoicing?

E-invoices travel through the Peppol network between secure, tracked access points, creating a verified audit trail from sender to recipient. This is more secure than emailing PDF invoices, which can be intercepted or altered. Because every access point on the network is tracked, this structured transmission reduces the risk of invoice fraud and lost documents.
