Fiscalization in Spain: What is the meaning of the so-called billing record in terms of fiscalization requirements?

Under Spain’s Royal Decree 1007/2023, a billing record is a digitally generated, tamper-proof file linked to each invoice or receipt, serving as the core document for fiscal audits rather than the invoice PDF itself. These records, required in real time (VERI*FACTU mode) or stored securely (SIF), contain structured metadata and digital fingerprints to ensure transparency, integrity, and traceability in compliance with Spanish fiscalization rules.

 

Well-known regulation for fiscalization in Spain—Royal Decree 1007/2023—has introduced digital billing records, transforming the way businesses manage invoices/receipts. These electronic files, generated upon invoice issuance, are designed to ensure transparency and prevent tampering through an immutable chain of records.

The Spanish Tax Agency (AEAT) requires these billing records to be sent immediately in VERI*FACTU mode, allowing real-time oversight. In Non-VeriFactu mode, they remain stored in the SIF (Spanish Tax Service), maintaining the same structure to ensure integrity and compliance upon request.

Each invoice issued through the SIF system is accompanied by a billing record, which serves as the primary reference for audit verification rather than a simple PDF. These records consist of standardized metadata, digital fingerprints, and a sequential chain linking them to prior transactions, allowing authorities to track all financial movements, including corrections and cancellations.

The regulation also clarifies that billing records differ from accounting entries, which represent revenue, VAT, and other financial transactions in a company’s bookkeeping. Businesses must ensure that their invoicing software generates and maintains billing records according to strict integrity and traceability requirements to remain compliant.
