Description

EU-compliant e-invoices: ZUGFeRD, Factur-X & PEPPOL. Auto-detected per country, VAT-validated.

Invoice9 automatically generates EU-compliant invoices for every Shopify order. It detects the buyer's country, selects the correct format (ZUGFeRD for Germany, Factur-X for France, PEPPOL for Belgium and Netherlands), validates EU VAT numbers via VIES, and sends the invoice by email — with no manual steps. Issue credit notes in one click, sync invoices to Google Drive, and support customers in their language with built-in multi-language invoice delivery.
