E-invoicing in Spain

Spain has adopted the regulatory framework for mandatory B2B e-invoicing, with practical go-live dates tied to the entry into force of the implementing ministerial order. The model builds on Spain’s existing public-sector e-invoicing experience through FACe and adds a new private-sector framework for business and professional transactions.

For businesses, Spain is now a market where planning must move from monitoring to execution. The exact compliance date depends on turnover and the final ministerial order, but the direction is clear: structured B2B e-invoicing will become mandatory.

What the mandate means

The Spanish B2B e-invoicing regime will require businesses and professionals to issue and receive structured electronic invoices through compliant systems. The rules are expected to support platform interoperability and invoice status exchange, making AP/AR process integration essential.

Spain is not starting from zero. FACe has long supported public-sector e-invoicing, and SII already gives the tax authority near-real-time visibility for many larger taxpayers. The B2B mandate adds a broader commercial invoice-exchange layer.

Does FACe handle B2B invoices?

FACe is central to B2G e-invoicing. The B2B mandate uses a broader framework that includes private platforms and public tools.
