İçeriğe atlaZUGFeRD embeds structured invoice XML inside a human-readable PDF — also known as Factur-X in France.
ZUGFeRD (Zentraler User Guide des Forums elektronische Rechnung Deutschland) is a hybrid e-invoice: a PDF/A-3 file with embedded EN 16931 XML. Recipients get both machine-readable data and a printable document.
Profiles range from MINIMUM (basic metadata) to EN 16931 (full semantic invoice). Factur-X is the French branding of the same standard. Tentaco validates embedded XML and PDF/A constraints in the browser.
