Retarus Press Release

E-Invoicing set to become mandatory in Germany

With Retarus, companies can effortlessly implement the new statutory requirements for electronic invoicing

Sydney, 07/06/2024 // From 2025, submitting electronic invoices will become mandatory for all German-based companies. They will be required to transmit and receive electronic invoices exclusively in a structured format. Businesses which have not yet adapted their billing processes to meet the new provisions urgently need to take action. There is hope for these companies: Retarus E-Invoicing fulfills all the new statutory requirements.

As of January 1st, 2025, it will become obligatory for all companies engaged in B2B transactions in Germany to receive e-invoices in line with EN 16931. The permitted formats are CII and UBL (XML), as well as Factur-X/ZUGFeRD (hybrid). Paper-based invoices will remain valid until December 31st, 2026. For one additional year, until December 31st, 2027, this transitional regulation will still apply for invoices issued by companies with less than €800,000 turnover per annum. Existing EDI connections in association with invoices which do not comply with EN 16931 will still be permitted until the end of 2027. However, even during this interim period, companies on the receiving end of “sundry” electronic formats, such as PDF, must explicitly give their consent. As the time and resources associated with implementing this change may be substantial, it is highly advisable to establish the appropriate project structures well in advance. This will facilitate timely implementation within the deadline.

Digitalize billing processes with Retarus E-Invoicing

Efficient process automation, furthermore, enables businesses to achieve significant time and cost savings. With Retarus E-Invoicing, companies digitalize the sending and receiving of invoices. Thanks to closely specified performance indicators for electronic invoices and high levels of data precision, Retarus E-Invoicing customers are in a position to optimize their cash flow and collaboration with suppliers. What’s more, Retarus’ solutions are scalable and can be integrated rapidly, granting the company access to international e-invoicing networks such as PEPPOL within a very short time frame. Every well-known ERP system can be connected without difficulty via EDI and APIs. Hybrid formats, which combine PDF and structured invoice data, for instance ZUGFeRD 2.0, can also be implemented. In this scenario, the Retarus E-Invoicing service digitizes (and structures) the unstructured, analog bills. As a certified PEPPOL access point and member of local e-invoicing associations, Retarus provides its customers with legally compliant e-invoicing services for B2G, B2B and B2C in Europe and around the globe – always adhering to international standards.
