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.
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.
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.
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.
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.
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.
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. The right standard is selected automatically based on your buyer's country, type, and requirements. No more juggling multiple tools or reading 400-page specification documents.
Real-Time Validation
Before your invoice reaches any tax authority, it passes through our validation engine: EN 16931 business rules, schema validation, calculation checks and country-specific requirements, verified in under three seconds. Errors come back with a human-readable explanation and the exact field path. Generated XML is additionally checked against the official EN 16931 Schematron in our test suite.
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.
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.
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.
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.

Three Steps. Fully Compliant.
From draft to legally compliant e-invoice in under a minute. No compliance expertise required.
Create Your Invoice
Fill in your invoice using our intuitive form, or import data from your existing systems. Select a client, add line items with products from your catalog, and let our engine auto-calculate VAT, totals, and compliance fields. The smart form adapts based on the buyer's country, showing exactly the fields needed for compliance.
Validate Instantly
Hit validate and the compliance rules run in real time: schema validation, calculation verification, required-field checks and country-specific rules, all in under three seconds. Errors are highlighted with a plain explanation and the field to fix. A green check means the invoice passed every rule the engine knows for that standard.
Export & Send
Choose your output: professional PDF, machine-readable XML, or hybrid PDF/A-3 with embedded XML for Factur-X and ZUGFeRD. Download the files, send them directly via email, or submit through connected tax authority portals. Your invoice is archived, tracked, and the status updates automatically as clients view and pay.

What Using InvoiceEU
Looks Like
Three situations the engine is built for, and the standard it applies to each.
Agency invoicing German public-sector clients
Invoicing German public-sector buyers means XRechnung, and a rejected invoice means chasing payment weeks later. Enter the invoice once; the engine detects that a German public buyer requires XRechnung, validates against the EN 16931 rules before you send, and shows exactly which field is wrong when one is.
Consultancy billing across several EU countries
Working across several EU countries means a different mandated format in each one. Pick the client and the standard follows from the seller country, the buyer country and the buyer type: Peppol BIS 3.0 for Belgium, Factur-X for France, XRechnung for Germany. One invoice form, one dashboard.
Business subject to the Polish KSeF mandate
The Polish KSeF requirements are strict and the official documentation is largely in Polish. The KSeF generator produces the required structure, and the validator reports problems in English with the field path, before anything is submitted.
