Peppol in Germany: What Is the Peppol Network? Complete Guide
Table of Contents
If you do business in Germany, or anywhere in Europe, you have probably come across the term "Peppol." But what exactly is it? How does it work? And why should you care?
This guide breaks down what you need to know about the Peppol network: the technology behind it, how it works in Germany, what it costs, and how to get started.
Quick answer: Peppol (Pan-European Public Procurement OnLine) is a global network for exchanging standardized electronic business documents, mainly e-invoices. It uses a four-corner model, where senders and receivers connect through certified access points rather than directly. Peppol is the preferred channel for e-invoices to German federal agencies, though it is not legally mandated.
Key Takeaways
- Peppol is a global network for exchanging standardized electronic business documents, primarily e-invoices.
- It uses a 4-corner model: senders and receivers communicate through certified access points, not directly with each other.
- In Germany, Peppol is the preferred transmission channel for e-invoices to federal government agencies.
- The Peppol network itself is free to use; costs come from your access point provider.
- Peppol is becoming increasingly important for B2B e-invoicing.
What Is Peppol?
Peppol stands for Pan-European Public Procurement OnLine. It started in 2008 as an EU-funded pilot project. Today, it has evolved into a global network for exchanging electronic business documents.
The Peppol network is governed by OpenPeppol, a non-profit international association based in Brussels.
Peppol is not software. It is an infrastructure and a set of standards. Think of it like the postal system.

How Does Peppol Work? The 4-Corner Model Explained
The Four Corners
- Corner 1 (C1), The Sender: Your business.
- Corner 2 (C2), Sender's Access Point: A certified Peppol access point.
- Corner 3 (C3), Receiver's Access Point: The certified access point used by the recipient.
- Corner 4 (C4), The Receiver: The business or government agency that receives the document.
Why does this matter? You never need a direct connection to your trading partner. As long as both parties are connected to the Peppol network, documents flow automatically.
The Technical Flow in 5 Steps
- You create an e-invoice in a Peppol-compliant format.
- Your system sends the document to your access point (C2).
- Your access point looks up the receiver's Peppol ID in the Service Metadata Publisher (SMP).
- The document is transmitted securely via the AS4 protocol to the receiver's access point (C3).
- The receiver retrieves the document from their access point.
Peppol in Germany
In Germany, the Koordinierungsstelle fuer IT-Standards (KoSIT), in cooperation with xeinkauf.de, serves as the Peppol Authority.
Current Status (2026)
- B2G: Peppol is the preferred transmission channel for e-invoices to federal government agencies.
- B2B: With Germany's e-invoicing obligation being phased in from 2025 onward, Peppol is gaining significant traction in B2B.
- State and Municipal Level: Many German states and municipalities also accept e-invoices via Peppol.
Important: To address German public sector recipients, you typically need a Leitweg-ID.
Peppol Access Points: What They Are and How to Choose One
A Peppol access point is a certified service provider that acts as your gateway to the Peppol network.
What Does an Access Point Do?
- Validates your documents against Peppol standards
- Looks up recipient addresses in the Peppol directory
- Transmits documents securely via the AS4 protocol
- Delivers incoming documents to your system
How to Choose the Right Access Point
| Criterion | What to Look For |
|---|---|
| Certification | Officially certified by OpenPeppol |
| Document Types | Does it support invoices only, or also orders, catalogs? |
| ERP Integration | Does it connect to your ERP system? |
| Country Coverage | Critical if you exchange documents internationally |
| Support | Response times, language support |
| Pricing Model | Per-transaction, flat fee, or hybrid? |
Pro tip: The best access point is the one that integrates cleanly with your existing accounting or ERP software.
Peppol ID: Your Address on the Network
Every participant on the Peppol network needs a unique Peppol ID.
A Peppol ID consists of two parts: a scheme identifier and the actual ID.
Example Peppol ID:
0204:991-12345-67Here, 0204 indicates the Leitweg-ID scheme, and 991-12345-67 is the specific Leitweg-ID of the recipient.
Peppol and XRechnung: How They Work Together
XRechnung is the format. Peppol is the delivery channel.
| Aspect | XRechnung | Peppol |
|---|---|---|
| What is it? | An invoice format (XML-based) | A transmission network |
| Purpose | Defines the content and structure | Transports the e-invoice |
| Standard | EN 16931 (German CIUS) | Peppol BIS, AS4 protocol |
| Mandatory? | Yes, for B2G in Germany | Preferred channel for B2G at the federal level |
In practice: you create your invoice in XRechnung format, then send it over the Peppol network.
Good to know: Both XRechnung and Peppol BIS Billing 3.0 are implementations of the European standard EN 16931. They are interoperable.
Peppol for B2B: The Growing Trend
- One connection, many partners: Instead of maintaining separate EDI connections, you connect once to Peppol.
- Scalability: Adding a new trading partner takes minutes, not months.
- Future-proofing: The EU's ViDA initiative is pushing Peppol as the backbone for pan-European B2B e-invoicing.
- Full automation: Peppol enables straight-through processing.
Is Peppol Free?
The Peppol network itself is free. OpenPeppol does not charge for document exchange.
However, you need an access point to connect to the network, and access points charge fees.
What Does Peppol Cost? Full Breakdown
| Cost Component | Typical Range | Notes |
|---|---|---|
| Peppol Network | EUR 0 | No fees from OpenPeppol |
| Access Point Monthly Fee | EUR 0 to 150/month | Some providers offer free basic tiers |
| Cost per Transaction (Sending) | EUR 0.10 to 1.50 | Depends on volume and provider |
| Cost per Transaction (Receiving) | EUR 0 to 0.50 | Many providers charge nothing |
| Setup / Onboarding | EUR 0 to 500 (one-time) | Depends on integration complexity |
| ERP Integration | EUR 0 to 5,000 (one-time) | Depends on your existing systems |
Cost tip: For small businesses with low invoice volume, some providers bundle Peppol into existing accounting software.
Peppol vs. Other Transmission Channels
| Criterion | Peppol | Email (PDF/XML) | Upload Portal | Direct AS4 | Classic EDI |
|---|---|---|---|---|---|
| Standardization | High | Low | Medium | High | High |
| Automation | Very high | Low | Medium | Very high | Very high |
| Setup Effort | Medium | Low | Low | High | Very high |
| Cost | Low to medium | Very low | Free | Medium to high | High |

Bottom line: Peppol offers the strongest combination of standardization, automation, and future-proofing.
