Peppol and Global E-invoicing Compliance

Peppol e-invoicing is a structured way for businesses to exchange electronic invoices across a secure, standardised network. Originally developed for public sector procurement in Europe, it is now expanding rapidly into business-to-business (B2B) transactions as more countries adopt it as part of their national e-invoicing mandates.

This guide covers how Peppol e-invoicing works, which countries have adopted it, and what businesses need to know about connecting to the network. For a broader introduction to Peppol itself, see our complete guide to Peppol.

What Is Peppol E-Invoicing?

Peppol e-invoicing is the exchange of structured electronic invoices through the Peppol network, a global infrastructure that connects businesses, governments, and their trading partners through certified access points.

Unlike sending a PDF invoice by email, Peppol e-invoicing transmits invoice data in a standardised machine-readable format, directly from one financial system to another. This means the data arrives in the receiver’s system ready to process, without manual re-entry or interpretation.

• Key characteristics of Peppol e-invoicing:
• Invoices are transmitted in structured formats, typically Peppol BIS Billing 3.0, which is based on the European standard EN 16931.
• Both sender and receiver must be connected to the Peppol network through a certified Peppol access point provider.
• Once connected, a business can exchange invoices with any other Peppol participant, regardless of which access point provider they use.
• The network is governed by OpenPeppol, a non-profit association that sets the standards and certifies access point providers globally.

Peppol e-invoicing is now mandated or officially supported in countries across Europe, Asia, and Australasia, and the UK has confirmed it will form the basis of its own 2029 e-invoicing mandate.

How Does Peppol E-Invoicing Work?

Peppol uses a “four-corner model” to route invoices between sender and receiver. Each party connects to the network through their own certified access point, and the two access points handle the secure transmission between them.

The four corners are:

• Corner 1: The invoice sender, typically a supplier.
• Corner 2: The sender’s Peppol access point provider, which formats and transmits the invoice.
• Corner 3: The receiver’s Peppol access point provider, which receives and delivers the invoice.
• Corner 4: The invoice receiver, typically a buyer or public authority.

In practice, a supplier generates an invoice in their ERP or accounting system. Their access point converts it to the correct Peppol format and transmits it securely through the network. The buyer’s access point receives it and delivers it directly into the buyer’s system, ready to process.

For a deeper look at the model and how it handles different document types, see our guide to the Peppol four-corner model.

Peppol adoption

• Europe (EU countries): Many EU countries are increasingly adopting or choosing Peppol as the preferred network and format for public procurement and e-invoicing (e.g.Belgium and Germany)
• Singapore: Leading in Asia, Peppol is one of the preferred methods for e-invoicing there and is heavily used in public procurement.
• Australia: Also developing as a Peppol hub; the Australian Federal Agency for Digital Transformation provides official support.

Which Countries Use Peppol E-Invoicing?

• EU: Directive 2014/55/EU has required contracting authorities to accept electronic invoices since 2019, increasing adoption of Peppol across member states.
• Germany: E-invoicing has been mandatory for federal suppliers since November 2020, with Peppol supported as a transfer option.
• Ireland: Pilot projects for e-invoicing in the public sector are underway, with broader adoption expected to follow EU-wide momentum.
• United Kingdom: Peppol is already used in UK public procurement, including the NHS. The UK government confirmed on 23 June 2026 that Peppol will form the central infrastructure for the 2029 B2B e-invoicing mandate. Read our full guide to the UK e-invoicing mandate.
• Singapore: E-invoicing is required in the business-to-government (B2G) environment, with Peppol adopted as the delivery framework.
• Australia: Peppol adoption is progressing through pilot phases, with gradual scaling across both public and private sectors.

Businesses operating across these markets can connect to the Peppol network through a single certified access point, simplifying compliance across multiple jurisdictions.

Local Peppol authorities and service providers

To ensure smooth and standardized e-invoicing across borders, each country designates national authorities or accredited service providers to manage Peppol access. These entities oversee compliance, certification, and connectivity within their respective regions. The following examples highlight how different countries organize their Peppol governance and approved service providers:

• Germany: National Clearing House / certified Peppol Access Point (e.g. B. portals of e-invoicing providers).
• Ireland & UK: Designated authorities or contracts with approved Peppol providers, often through public procurement bodies.
• Singapore: The Infocomm Media Development Authority (IMDA) is central Peppol Authority.
• Australia: Digital Transformation Agency and tech suppliers coordinate Peppol integration.

Peppol Around the World

PEPPOL was originally developed in the EU context but is now used globally. By March 2025, over 1.4 million organizations in 98 countries were registered as Peppol participants.

Outside Europe, countries such as Singapore (since May 2018), Japan (from September 2021), Australia, and New Zealand operate as independent Peppol organizations. Authorities.

What Does a Peppol E-Invoice Look Like?

A Peppol e-invoice is a structured data file, not a PDF or scanned image. It contains the same information as a traditional invoice, but in a machine-readable format that can be processed automatically by the receiver’s financial system.

The most widely used format is Peppol BIS Billing 3.0, based on the European standard EN 16931. A Peppol invoice in this format will typically include:

• Seller and buyer identification, including their Peppol IDs.
• Invoice number, issue date, and due date.
• Line-item detail: description, quantity, unit price, and VAT rate for each item.
• Total amounts including net, VAT, and gross figures.
• Payment terms and bank account information.

This structured data travels through the Peppol network from the sender’s access point to the receiver’s access point. At no point does the buyer need to manually key the data into their system. The invoice arrives in a format their software can read and process directly.

For businesses preparing for the UK mandate or connecting to Peppol for the first time, TrueCommerce handles the formatting and transmission automatically through your ERP. Speak with a Peppol expert to understand how this works for your specific setup.

The rules and timelines for e-invoicing are constantly changing from country to country. What is planned today might be delayed, updated, or replaced tomorrow, which makes it difficult for companies to keep track of everything. This complexity is exactly why many organisations look for a partner who can guide them through the different national requirements.
