The Problem

EU E-Invoicing Is a Maze.
We're the Map.

The European Union is mandating electronic invoicing across all member states. For small businesses trading across borders, that means navigating a labyrinth of country-specific standards, validation rules, and tax authority portals — all with strict deadlines and real consequences for non-compliance.

12+

Different Standards

Peppol, UBL, CII, Factur-X, XRechnung, KSeF, myDATA — every country has its own rules, formats, and submission systems. One wrong namespace and your invoice gets rejected.

€50K+

Potential Fines

Non-compliant invoices aren't just rejected — they carry real penalties. Tax authorities across the EU are enforcing e-invoicing mandates with increasing severity.

40+

Hours per Month

That's how long the average micro-business spends wrestling with compliance. Hours that could go toward winning new clients, building products, or simply going home on time.

27

EU Countries

Each with different mandate timelines, tax authority portals, validation rules, and required fields. Sell across borders? Multiply the complexity.

You shouldn't need a compliance team to send an invoice.
InvoiceEU handles the regulations — you handle your business.

Features

Everything You Need to Invoice
Across Europe

Six powerful capabilities, one unified platform. Built from the ground up for the unique challenges of European e-invoicing compliance.

01

Multi-Standard Engine

One platform. Every European e-invoicing standard. Our engine generates legally valid XML in Peppol BIS 3.0, UBL 2.1, UN/CEFACT CII, Factur-X, XRechnung, KSeF, and myDATA formats — automatically selecting the right standard based on your buyer's country, type, and requirements. No more juggling multiple tools or reading 400-page specification documents.

7 standards supported
Multi-Standard Engine
02

Real-Time Validation

Before your invoice reaches any tax authority, it passes through our validation engine — 150+ business rules, schema validation, calculation checks, and country-specific requirements verified in under 3 seconds. Catch errors instantly with clear, human-readable explanations and exact field-level guidance. Never submit a non-compliant invoice again.

150+ rules checked
Real-Time Validation
03

Smart Country Detection

Selling to a German government entity? We'll auto-select XRechnung and ensure Leitweg-ID is included. French B2B client? Factur-X with Chorus Pro compatibility. Polish partner? KSeF-ready XML. Our intelligent detection engine analyzes the seller country, buyer country, client type (B2B, B2C, B2G), and applicable mandate to choose the exact right standard — every time.

Zero configuration needed

04

One-Click PDF & XML Export

Generate beautiful, professionally designed PDF invoices alongside machine-readable XML in a single click. Need hybrid documents? We produce PDF/A-3 with embedded XML for Factur-X and ZUGFeRD compliance. Every document is archival-quality, legally binding, and ready for immediate submission to any tax authority portal or Peppol access point.

05

VAT Compliance Engine

European VAT is legendarily complex — standard rates, reduced rates, zero-rated, exempt, reverse charge, intra-community supply, triangulation. Our VAT engine knows every rate for every EU country, automatically applies the correct treatment based on the transaction type, and validates VAT numbers against VIES in real-time. Cross-border calculations? Handled.

All 27 EU countries covered

06

Client & Product Management

Maintain your complete customer and product catalog with built-in VAT number verification, Peppol ID management, and e-invoicing address resolution. Each client is classified (B2B, B2C, B2G) so the right compliance rules apply automatically. Products come with UN/ECE unit codes, CPV commodity codes, and tax category classification — everything your e-invoices require.

Don't take our word for it — hear from the European business owners who eliminated their compliance headaches.

We were spending two full days every month manually converting invoices for our German government clients. InvoiceEU reduced that to literally 10 minutes. The XRechnung validation catches errors we never would have found — our rejection rate went from 15% to zero.

🇩🇪Germany

As a Belgian consultancy working across 4 EU countries, compliance was our biggest operational headache. InvoiceEU handles Peppol for Belgium, Factur-X for France, XRechnung for Germany — all from one dashboard. The auto-detection is brilliant. I just select the client and it figures out the rest.

KSeF compliance had us genuinely worried. The Polish tax authority requirements are strict and the documentation is mostly in Polish. InvoiceEU made it painless — their KSeF generator handles all the edge cases, and the real-time validation gives us confidence every invoice will be accepted.
