Introduction

NIZU Facturae 3.2.1 is the official electronic invoicing format used in Spain, supported and regulated by the Agencia Tributaria (AEAT) and the Ministerio de Asuntos Económicos y Transformación Digital.

Through this integration, NIZU WorkSpace Cloud allows Spanish companies to generate, sign, and send digital invoices fully compliant with Spanish e-invoicing regulations.

The Facturae format (v3.2.1) is based on an XML structure that defines all necessary fiscal data, including issuer, recipient, tax details, and digital signatures.

It ensures that invoices are both machine-readable and legally valid, meeting the standards required for both B2G (Business-to-Government) and B2B (Business-to-Business) transactions.

Why It Matters

Spain’s public administrations have been fully digital for years, and upcoming legislation will soon make electronic invoicing mandatory for all private companies.

By implementing NIZU Facturae 3.2.1, your organization will stay compliant, efficient, and ready for Spain’s transition to a 100% paperless invoicing ecosystem.
