About Komplyo E-Invoicing
From the official readme · v1.0.0Description
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.
Installation
- Install and activate the plugin (WooCommerce must be active).
- Create a free account at https://getkomplyo.com and copy your API key.
- In WordPress, go to WooCommerce → Komplyo E-Invoice and paste your API key (and Komplyo API URL if self-hosted).
- Set your business profile (name, VAT ID, address, IBAN) in your Komplyo dashboard.
- Done. Paid/completed orders now become compliant e-invoices automatically.
