See every featureBilloop connects directly to your Shopify store and automatically generates structured e-invoices in Factur-X CII and UBL formats - the standards required across the EU and beyond. Every invoice is built from your real order data, ensuring accuracy and compliance. You can also generate invoices manually straight from the order page.
Default Shopify order PDFs are not structured e-invoices. BOO creates Factur-X invoices when orders are paid: a readable PDF with embedded EN 16931 XML, sequential numbering, buyer email delivery, and durable storage for download. EU B2B merchants can configure VAT mapping and reverse charge, issue credit notes for refunds, and export ZIP, FR, or DATEV-friendly packs for accountants from admin.
