Peppol Access Point Germany 2026: How it works and Registration Guide

From January 1, 2025, businesses in Germany must have been able to receive structured e-invoices, but mandatory B2B e-invoice issuance starts from 2027. Unsurprisingly, many businesses are looking at Peppol Access Points to send and receive e-invoices. 

Key Takeaways

• Germany requires businesses to issue EN 16931-compliant e-invoices from January 1, 2027. 
• While a Peppol Access Point is not mandatory, it remains a widely used option for structured invoice exchange.
• KoSIT serves as Germany's Peppol Authority and maintains the XRechnung standard.
• Public sector invoices typically require XRechnung and a Leitweg-ID. 
• Businesses can connect through certified providers without operating their own Peppol Access Point.

What is a Peppol Access Point?

A Peppol Access Point links your organization to the Peppol eDelivery Network. Without it, you cannot exchange documents through Peppol. It handles the secure sending and receiving of invoices and other business documents using agreed standards.

Who Needs a Peppol Access Point in Germany?

Germany does not mandate Peppol. But for many businesses, it is the easiest path to compliant invoice exchange.

1. Businesses Sending Electronic Invoices

Businesses preparing for Germany's phased B2B e-invoicing rollout may choose to use a Peppol Access Point to issue structured invoices efficiently.

The issuance requirement applies:

• From January 1, 2027, for businesses whose 2026 turnover exceeds €800,000.
• From January 1, 2028, for all remaining businesses.

Although not mandatory, Peppol is widely adopted for standardized domestic and cross-border invoice exchange.

2. Businesses Receiving Electronic Invoices

From January 1, 2025, businesses must be able to receive e-invoices. They can also check if Peppol fits their invoice volumes, supplier base, and digitalization goals.

3. Suppliers to Public Authorities

Businesses that invoice federal, state, or local government entities frequently use Peppol because many public sector organizations are reachable through the network.

These invoices often require:

• XRechnung compliance.
• Buyer reference information.
• Leitweg-ID details.
• Additional procurement-related information.

For organizations serving government customers, Peppol is often essential, even when not mandatory.

How Does a Peppol Access Point Work? The 4-Corner Model

The Peppol network operates through a four-corner model that allows participants to exchange invoices without establishing direct technical connections with every trading partner.

Invoice Flow Through the Network

1. The sender creates an invoice in a compliant format such as Peppol BIS Billing or XRechnung.
2. The invoice is submitted to the sender's Access Point.
3. The Access Point validates the invoice. Then it identifies the recipient's endpoint using Peppol metadata services.
4. The invoice is then sent through the Peppol network safely.
5. The receiving Access Point validates the message and forwards it to the recipient's system.
6. The recipient's system processes the invoice automatically.

Standards Used Within the Network

Several standards support invoice exchange through Peppol:

Why Peppol Access Points Are Important?

Despite Germany's B2B e-invoicing rules not requiring Peppol, ignoring it may be impractical for your business.

1. Support for Regulatory Compliance

Peppol Access Points are one of the most practical ways to exchange EN 16931-compliant invoices. They provide a standardized framework for transmission and validation. Their importance is even greater in public sector invoicing, where many authorities are accessible through the Peppol network and require XRechnung-compliant invoices.

2. Secure Invoice Exchange

Peppol participants must meet technical and security requirements established by OpenPeppol. This creates a controlled network where organizations can exchange invoices through verified endpoints rather than open email channels.

3. Interoperability Across Systems

Another biggest strength of Peppol is that it replaces countless one-off integrations with a single standardized connection. Instead of building separate invoice exchange links for every customer and supplier, organizations connect once to the Peppol network and can transact with all reachable participants.

4. Automation and Operational Efficiency

Structured invoice data should eliminate most manual invoice entry. When invoice information is exchanged in a structured format, details such as supplier information, tax amounts, purchase order references, and payment terms can move directly into ERP and accounting systems. There is no need to re-key. This cuts down transcription errors and speeds up invoice processing.

5. Cross-Border Invoice Exchange

Peppol supports invoice exchange across multiple countries through a single network connection. This eliminates the need for multiple bilateral EDI arrangements and simplifies international invoicing.

6. Support for German Public Sector Requirements

Germany may have adopted XRechnung as its national e-invoicing standard for public procurement, but compliance is only part. Peppol Access Points help businesses exchange XRechnung-compliant invoices, connect with public authorities, support Leitweg-ID requirements, and improve invoice routing accuracy.

Difference Between Peppol Access Point vs Service Provider

These two concepts are related. But they are not the same. 

How to Register and Connect with a Peppol Access Point in Germany?

Germany does not have a centralized registration process for businesses joining the Peppol network. Instead, you select a certified provider and complete onboarding through that provider.

Step 1: Select a Provider

Providers can be very different. It is worth checking a few things before making a choice:

• EN 16931 compliance support.
• XRechnung capabilities.
• ERP integration options.
• Cross-border invoicing requirements.
• Customer support quality.
• Pricing structure and scalability.

If your business operates internationally, you should also assess whether the provider supports invoice exchange across many countries.

Step 2: Obtain a Peppol Identifier

You need a Peppol participant identifier to exchange documents through the network.

Common identification schemes include:

• VAT ID scheme (9930).
• GLN scheme (0088).
• IBAN scheme (9918) when other identifiers are unavailable.

If you are a public sector entity, your identifier may be linked to your Leitweg-ID through the 0204 scheme. Your provider will assist with participant registration and metadata publication.

Step 3: Complete Business Registration

Providers generally request:

• Company legal name.
• Registered address.
• VAT registration information.
• Contact details.
• Technical integration requirements.
• Estimated invoice volumes.

Step 4: Choose an Integration Method

Most providers offer many integration approaches:

Step 5: Testing and Validation

Before production activation, your provider will typically perform testing to verify:

• Invoice format validation.
• Participant registration.
• Routing accuracy.
• End-to-end document delivery.
• Integration performance.

Step 6: Production Activation

After setup, you're ready. You can exchange invoices with customers, suppliers, and public authorities through Peppol.
