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.

• Create Factur-X invoices automatically when orders are paid
• Email buyers a PDF with embedded e-invoice XML after each sale
• Apply sequential invoice numbering ready for EU accounting
• Issue credit notes linked to the original invoice on refunds
• Export invoice packs for accountants (ZIP, FR, DATEV-friendly)
