Ley Crea y Crece – Spain’s interoperable B2B e-invoicing model
Understanding Spain’s B2B eInvoicing model under Ley Crea y Crece
Key implementation dates
Key milestones in the phased rollout of Spain’s B2B eInvoicing framework
These dates reflect the phased implementation timeline currently derived from Royal Decree 238/2026 and the draft Ministerial Order published in April 2026. The draft Order foresees its entry into force on 1 October 2026, which would trigger the 12-month and 24-month adaptation periods established for companies above and below the €8 million turnover threshold. Beyond the rollout dates, businesses should also prepare for the operational impact of invoice-status communication, interoperability requirements and integration with the public e-invoicing solution.

How Spain’s Ley Crea y Crece eInvoicing model works
Implementation
The mandate will apply in phases once the Ministerial Order enters into force: first to businesses with annual turnover above €8 million, and later to all other companies and self-employed professionals
Tax Authority
Agencia Estatal de Administración Tributaria (AEAT) – Spanish Tax Agency
Format
Invoices must be exchanged in structured, machine-readable formats that support interoperability. Common formats referenced in Spain include Facturae, UBL, EDIFACT and UN/CEFACT XML, with UBL playing a central role in the public e-invoicing solution
Digital Signature
Compliance solutions must ensure authenticity, integrity and traceability
Archiving
Electronic invoices must be stored for at least 4 years in line with Spanish tax record-keeping requirements
Invoice Status Communication
Invoice-status communication is a core part of Spain’s B2B e-invoicing framework. Recipients must report key events such as rejection and payment, while issuers must be able to receive, register and reconcile those updates within their ERP and compliance processes

Frequently asked questions
Who is required to use e-Invoicing under the "Ley Crea y Crece"?
What formats are allowed for electronic invoices?
The framework relies on structured, machine-readable invoice data designed for interoperability. Several structured formats are referenced in the Spanish market, including Facturae, UBL, EDIFACT and UN/CEFACT XML. For the public e-invoicing solution, the draft Ministerial Order defines UBL under the EN16931 semantic model as the key technical basis. Status-related communications are also structured through UBL ApplicationResponse messages.
Is an electronic signature mandatory for e-invoicing?
Who reports invoice statuses under the Spanish model?
How does the public solution interact with private platforms?
Does the law apply to B2G transactions as well?
No, the “Ley Crea y Crece” focuses on B2B transactions. However, B2G einvoicing has been mandatory in Spain since 2015 through the FacturaE system.
Different Frameworks for SAP Integration And Ley Crea Y Crece Compliance
Ley Crea y Crece marks an important milestone in the digitalization of Spain’s B2B invoicing model. It requires the electronic exchange of structured invoices between businesses, private platforms and the public e-invoicing solution, together with mandatory invoice-status communication.
As a result, SAP and ERP systems must be able to generate compliant invoice data, validate structured formats such as UBL, submit faithful copies when required, exchange messages with public or private platforms, and reconcile invoice statuses within finance and compliance processes.
At Code10, we support this transition through SAP standard capabilities via the Document and Reporting Compliance framework, combined with advanced eCompliance integration delivered through our eCompliance Hub. This allows companies to prepare for Spain’s B2B e-invoicing mandate with a scalable architecture for invoice generation, validation, transmission, status tracking and long-term regulatory maintenance.
