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.

E-invoicing is no longer a future ambition – it is becoming the standard way businesses exchange invoice data across Europe and beyond. Driven by regulatory initiatives such as ViDA (VAT in the Digital Age), companies are moving away from PDFs and manual data entry towards structured, automated, and compliant invoice processing.
