Spain Confirms B2B E-Invoicing Direction: October 2027 Go-Live with Decentralised Exchange and Reporting Layer
Spain’s B2B e-invoicing mandate has moved into a more defined implementation phase, with the latest timeline pointing to 1st October 2027 for large businesses and 1 October 2028 for all taxpayers.
These dates stem from the draft Ministerial Order, which would take effect from 1st October 2026, although final approval is still pending.
The model is structured as a decentralised exchange framework. Businesses will be required to issue structured e-invoices in formats including Facturae, UBL, CII or EDIFACT, transmitted either via certified private platforms or through a public AEAT-provided solution. Interoperability between platforms is mandatory, requiring providers to support seamless exchange regardless of network or vendor.
Unlike some European peers, Spain has not formally mandated the Peppol network. Instead, it is building its own national infrastructure, although alignment with EN 16931 and use of UBL creates technical compatibility with Peppol-based ecosystems.
Beyond invoice exchange, Spain will introduce mandatory lifecycle reporting. Recipients must communicate invoice statuses — including acceptance, rejection and payment — within a four-day window. This reporting obligation operates alongside the exchange model, adding a near real-time visibility layer across transactions.
A transitional measure applies during the first 12 months following go-live, requiring issuers to provide a human-readable PDF version of the invoice unless the recipient explicitly waives this requirement.
Scope covers all domestic B2B transactions involving businesses and self-employed professionals, with B2C and cross-border transactions excluded for now. The treatment of non-resident entities remains subject to further clarification.
The regime operates independently of Spain’s VeriFactu framework, which governs certified billing software and anti-fraud controls under a separate timeline.
Key implementation variables remain open, including final technical specifications, platform certification requirements, and aspects of scope interpretation, pending publication of the final Ministerial Order.
