Our MailCenter E-Invoice add-on enables companies to create, process and send XRechnungen directly in their SAP system – quickly, easily and in compliance with legal requirements. Existing SAP systems are not designed for the creation and processing of XRechnung by default. With our add-on, you can generate your invoices correctly, efficiently and in compliance with the law. All you have to do is add our extension to your SAP system and configure it briefly. Our solution integrates seamlessly with your existing SAP system, helping you meet new requirements and increase operational efficiency.

What is XRechnung?

XRechnung is a standardized format for electronic invoices, based on the European standard EN 16931. It was developed to ensure the uniform and automated exchange of invoice information between companies and public administrations in the EU.

Why is XRechnung becoming increasingly important for companies?

With the increasing digitization of accounting and the legal obligation to accept electronic invoices in the public sector, XRechnung is becoming essential. It enables automated processing, reduces administrative effort, minimizes errors and lowers costs. In addition, the use of electronic invoices contributes to sustainability by reducing paper consumption.

E-invoicing obligation from 2025

From 2025, the e-invoicing obligation in Germany will be extended to the entire B2B sector. All companies will then have to issue invoices electronically and in XRechnung format. This regulation promotes digital transformation, increases efficiency and transparency in accounting, and forces companies to modernize their processes.
Are you looking for a simple solution for sending electronic invoices in SAP ECC or S4/HANA? Then our MailCenter software is the right choice. If you have any questions, please do not hesitate to contact us.

FAQ – MailCenter XRechnung

Starting situation

The XInvoice specifies a digital format for electronic invoicing. It was determined by the IT Planning Council for the Federal and State Governments.
In this way, Germany is creating a uniform format for electronic invoicing. This is in line with the requirements at European level under EU Directive 2014/55/EU. As an electronic invoice, only this format is accepted by all contracting authorities in the public sector.
Conventional invoicing by paper or simple PDF is no longer possible. Each country has its own peculiarities and formats.
E-RECHNUNG.GV.AT is the method of sending electronic invoices to the public administration. Companies in Austria.

From 2025, e-invoicing will be mandatory in Germany. XRehnung can also be used for this.

Motivation – electronic invoicing directly from SAP ERP

Due to the obligation to use digital invoices, we have developed an extension for XRechnungen and ZUGFeRD for our MailCenter customers. Our goal is the optimal exchange of electronic invoices between business partners and authorities.
This solution is fully integrated with SAP ERP. This allows you to create, validate and send invoices according to the German XInvoice format. The creation takes place directly in the course of invoicing with SAP.

If you send electronic invoices directly from SAP to your customers, this has decisive advantages:

  • All data is processed in SAP. This means that you do not have duplicate data storage, media breaks or cumbersome communication channels.
  • Due to the simple configuration, you can make adjustments yourself in case of changes to the standard. As a result, you don’t need programming adjustments or expensive consultants.
  • Little configuration is required. This means that you are fully operational after a short time to send invoices.

What is Peppol?

The Pan-European Public Procurement OnLine (PEPPOL) is an international project. It is used to standardise cross-border, electronically supported public procurement procedures within the European Union.
The aim is to speed up the electronically supported public tendering and procurement process and thus save costs.
PEPPOL supports E-invoicing Directive 2014/55/EU. HOWEVER, PEPPOL is not limited to the exchange of invoices (E-Invoicing) such as ZUGFeRD. It covers the entire electronic procurement process.
PEPPOL allows the exchange with all registered partners in the network via a connection. Access is via so-called access points.

Benefits of PEPPOL

PEPPOL brings benefits to public and private organizations. Some of the key benefits include:

  • Cost savings: PEPPOL’s streamlined processes lead to significant cost reductions in public procurement.
  • Greater efficiency: Electronic procurement via PEPPOL speeds up the tendering and procurement processes, resulting in faster results.
  • PEPPOL follows the EU Directive 2014/55/EU on electronic invoicing and complies with EU regulations.
  • Secure communication: Encrypted communication via AS4, SSL and TLS guarantees the security of sensitive information.
  • Reliability: PEPPOL provides shipping and technical confirmations that guarantee users a successful transaction.
  • Wide connectivity: PEPPOL allows exchanges with all partners registered in the network through a single connection.
  • Uniform standards: The use of defined standards such as UBL ensures uniform communication.
