Peppol Network Guide: What It Is and How to Get Connected

Article overview

This article explains Peppol Network Guide: What It Is and How to Get Connected as a practical reference for European e-invoicing. It defines the topic in plain language, places it in the compliance context, and connects the explanation to invoice formats such as XRechnung, ZUGFeRD/Factur-X, UBL, and CII.

Peppol: The Backbone of European E-Invoicing

Peppol (Pan-European Public Procurement On-Line) is an interoperability framework and network for exchanging structured business documents, including invoices, between connected organisations. It supports domestic and cross-border trade; whether you must use it depends on the rules in your country and the requirements of your trading partners.

At Invoice-Converter.com, we help businesses prepare UBL invoices for Peppol workflows and recipient-side validation. This guide explains everything you need to know about Peppol.

What is Peppol?

Peppol is an international framework that standardizes how businesses and governments exchange electronic business documents. It began as an EU public-procurement project and is now governed by OpenPeppol AISBL, a non-profit association based in Belgium.

Think of Peppol like email for business documents: just as you can send an email from Gmail to Outlook without worrying about compatibility, Peppol allows you to send invoices from one system to another, regardless of the software being used.

The 4-Corner Model Explained

Peppol uses a "4-corner model" for document exchange:

This model ensures that documents are routed securely and that both parties don't need to use the same software or provider.

Peppol ID: Your Business Address on the Network

Every participant on Peppol has a unique identifier called a Peppol ID (also known as Peppol Participant Identifier). This typically consists of:

• A scheme code (e.g., 0106 for Belgian company numbers, 0190 for Dutch KvK numbers)
• Your organization's identifier (e.g., your VAT number or company registration)

Example: A Belgian company with enterprise number 0123.456.789 would have Peppol ID: 0208:0123456789

How to Connect to Peppol

To send and receive documents via Peppol, you need to connect through an Access Point. Here are your options:

Option 1: Through Your Accounting Software

Many modern accounting systems have built-in Peppol connectivity or partnerships with Access Points. Check if your software offers Peppol integration.

Option 2: Dedicated Access Point Provider

You can sign up with a Peppol-certified service provider. The provider handles the technical connection, participant discovery and transport rules. Use the current OpenPeppol service-provider directory, or ask your accounting-software vendor which certified providers it supports.

Option 3: Hybrid Approach

Use Invoice-Converter.com to prepare UBL invoices from your existing PDFs for Peppol workflows, then submit them through your Access Point or government portal after validation. This is ideal if you're transitioning to full Peppol connectivity.

Peppol BIS Billing 3.0: The Invoice Format

Peppol uses Peppol BIS Billing 3.0 as its standard invoice format. This is based on:

• UBL 2.1: Universal Business Language XML syntax
• EN 16931: European e-invoicing standard (core invoice model)
• Peppol CIUS: Additional business rules specific to Peppol

The format ensures that invoices can be processed automatically by any system connected to Peppol, regardless of the recipient's software.

Benefits of Using Peppol

• Interoperability: Send to any Peppol participant worldwide
• Security: Encrypted transmission with verified identities
• Compliance support: Peppol BIS Billing is based on EN 16931; you still need to meet the specific legal and tax rules that apply to your transaction
• Automation: Enables straight-through processing
• Cost Reduction: Lower processing costs than paper or email
• Speed: Real-time delivery instead of postal delays
