Komplyo E-Invoicing

Germany’s B2B e-invoicing mandate is here: businesses must be able to receive structured e-invoices since 1 January 2025, and issuing becomes mandatory in 2027–2028. A normal PDF is no longer a valid invoice for B2B.

Komplyo connects your WooCommerce store to the Komplyo e-invoicing service. When an order is paid or completed, Komplyo automatically:

• generates a compliant ZUGFeRD (PDF + embedded XML) or XRechnung (UBL) document to the EN 16931 standard;
• validates every invoice (VAT IDs, mandatory fields, totals) before it goes out — and verifies VAT numbers in real time against the official EU VIES service;
• gives you an email-ready hybrid PDF, with Peppol delivery available where required.

Your business details (name, VAT ID, address, IBAN) are kept once in your Komplyo profile and applied to every invoice — the system never invents data.

This plugin is the WooCommerce connector. It requires a Komplyo account (a free tier is available at https://getkomplyo.com).

Why Komplyo

• Dedicated to German/EU e-invoicing compliance — not a generic PDF tool.
• Correct format chosen automatically (ZUGFeRD for B2B, XRechnung where needed).
• Real-time EU VIES VAT validation — the #1 cause of rejected e-invoices.
• Light, professional, no accounting knowledge required.
