About the Invoice9
Invoice9 automatically creates EU-compliant e-invoices for every Shopify order. The app detects your customer's country and generates the right format: ZUGFeRD for Germany, Factur-X for France, and PEPPOL for Belgium and the Netherlands. It validates EU VAT numbers through VIES, applies reverse charge when needed, and emails invoices to customers with no manual work required. Create credit notes in one click, sync all invoices to Google Drive, and deliver documents in multiple languages. Every invoice uses sequential numbering and comes as a branded PDF/A-3 file with embedded XML data.
