Mandatory e-invoicing from 1.1.2025

The introduction of the obligation to receive e-invoices in the B2B sector starting in 2025 in Germany marks a significant change in invoicing practices for companies. This development reflects an inevitable trend towards the standardization of financial transactions that is already emerging in many European countries.

In the B2G sector, e-invoicing in various formats such as XRechnung was introduced as early as 2014 in the first EU countries. Starting from January 1, 2025, all B2B companies in Germany must legally be able to receive e-invoices as well.

What exactly is an e-invoice?

An e-invoice is defined by its form: it is an invoice that is created in a machine-readable, structured format and is transmitted and received electronically. This structure enables automated processing in accounting systems, which reduces manual intervention and increases efficiency.

The European standard EN 16931 forms the basis for the formats of electronic invoices. This standard was developed to ensure the compatibility of invoicing processes across national borders and thus promote efficiency in the European single market.

The essentials:

  • From January 1, 2025, all B2B companies in Germany will be required to be able to receive and process e-invoices.
  • From 2025, traditional PDF invoices and paper invoices will no longer meet the legal requirements for e-invoices.
  • Electronic invoices must be created in a defined, digital format, such as the XRechnung invoice format, the EDI process and the ZUGFeRD invoice.
  • According to the DIN EN 16931 standard, these e-invoices must contain more extensive details than traditional invoice formats.
  • There are transitional periods for sending e-invoices (outgoing invoices) until December 31, 2027.

What does the e-invoicing obligation mean for your company?

Starting from January 1, 2025, receiving e-invoices will become mandatory for all B2B transactions in Germany. With the introduction of e-invoicing, a distinction is made between “electronic invoices” and “other invoices.” Electronic invoices include formats such as XRechnung, EDI (Electronic Data Interchange), and ZUGFeRD invoices. The standard for electronic invoices is defined by the European norm EN 16931. Simple PDFs or paper invoices will no longer meet these requirements.

From the first day of the regulation, all companies must be able to receive and process e-invoices. This includes the secure archiving of invoices for auditing purposes.

Transitional arrangements and adjustment period

Beginning in early 2025, the obligation to receive e-invoices will come into force without a transitional period. However, issuers have until the end of 2027 to fully transition their systems to meet the new requirements. Between 2025 and 2027, various forms of traditional and electronic invoices are permissible if they have the recipient’s consent. This includes paper invoices and PDFs, which can be used until the end of 2026. Businesses with annual revenues below 800,000 euros may continue using these formats until the end of 2027.

From 2028, all B2B companies in Germany must strictly comply with the new requirements for electronic invoices, which marks the complete transition to compliant e-invoices.

Preparation for mandatory e-invoicing

Switching to digital processing of all incoming and outgoing invoices requires a revision of your internal systems and processes. Currently, there are no specific legal requirements regarding the transmission method of e-invoices. However, it is generally expected that companies establish a system capable of receiving invoices through secure electronic channels such as EDI or Peppol.
