Can you handle ZUGFeRD + XRechnung e-invoicing for B2B (mandatory 2025+)?

Yes, this is the most under-estimated Berlin-rebuild scope right now. Germany's B2B e-invoicing mandate (Wachstumschancengesetz) phases in from 1 January 2025: all DE-to-DE B2B businesses must be able to receive structured electronic invoices; from 2027 mid-sized companies must also send them; from 2028 it covers everyone. Two formats matter: XRechnung, pure XML, the public-sector format (used since 2020 for B2G invoices via Peppol). ZUGFeRD, hybrid PDF/A-3 with embedded XML (UN/CEFACT CII or UBL inside), the B2B private-sector workhorse. We wire ZUGFeRD/XRechnung into Magento by: (1) hooking into the invoice-saved event to auto-generate hybrid PDFs server-side using mustangproject or pdfbox + a CII XSLT; (2) validating against the official ZUGFeRD validator; (3) wiring USt-IdNr validation at checkout for B2B carts; (4) storing the hybrid PDF in your GoBD-compliant 10-year archive. We also integrate with Peppol access points for B2G.
