Germany is one of Europe’s most important e-invoicing markets, with a strong focus on standardized formats and interoperability. Its approach differs from centralized platforms seen in other countries, relying instead on structured formats and network-based exchange. In this deep dive, we explain how e-invoicing works in Germany, which formats and networks are used, and how the German implementation is being rolled out over time.

E-invoicing is rapidly becoming the standard for invoice exchange across Europe. While each country follows its own implementation path, the overall direction is clear: structured invoice data, digital exchange, and increased transparency for tax authorities. This blog provides a high-level overview of how e-invoices are exchanged across key European countries, and how Onventis supports these different models.

As e-invoicing becomes mandatory across Europe, many organizations face the same question: How do we connect to e-invoicing networks without adding complexity to our AP landscape? In this blog, we explain why an integrated Access Point approach is the easiest, most cost-effective, and most future-proof way to receive e-invoices.

In this blog, we explain the difference between international networks and national platforms, how these networks operate, the role of Access Points, and how common network architectures—such as the 5-corner model and the V-model—shape invoice exchange across Europe.
