Spain’s B2B E-Invoicing Mandate in 2027: Updated Timelines, What Has Changed, and How to Prepare

What finance, tax, and IT leaders need to know about Spain’s evolving e-invoicing landscape

In our last update about Spain’s e-invoicing mandate in April 2025, the regulation was in a state of flux. The headline then was that Veri*Factu would go live on 1 January 2026, with the broader B2B mandate following in 2027 for large businesses and 2028 for everyone else. Fourteen months later, the timelines have shifted again, and the picture is clearer, if not yet fully complete.

This article brings you up to date with what has changed since that original piece, explains how the two regulatory tracks (Veri*Factu and Crea y Crece) relate to each other, and sets out what finance, tax, and IT leaders operating in Spain should be planning for today.

The most significant development in the intervening period was Real Decreto-ley 15/2025, published on 2 December 2025. This decree formally postponed the Veri*Factu obligations, pushing the originally planned January 2026 go-live date back by a full year. The new dates are:

• 1 January 2027: Veri*Factu becomes mandatory for Corporate Income Tax (IS) payers, primarily legal entities
• 1 July 2027: Veri*Factu becomes mandatory for the self-employed (autónomos) and all other taxpayers not covered by the January date

One item was not delayed: software manufacturers were still required to make certified Veri*Factu-compliant invoicing software available from 29 July 2025. Businesses using off-the-shelf accounting platforms should check with their vendors whether this milestone was met.

On the Crea y Crece B2B mandate side, the Ministerial Order that formally activates the implementation dates remains pending as of mid-2026. However, the expected dates have solidified in official communications:

• 1 October 2027: Mandatory B2B e-invoicing for large taxpayers (annual turnover > €8 million)
• 1 October 2028: Mandatory B2B e-invoicing for SMEs, sole traders, and all other businesses

Two Tracks, One Destination

Spain’s approach to e-invoicing is structured around two overlapping but distinct obligations. Understanding how they relate is essential to planning.

Veri*Factu: Anti-Fraud Reporting, Not Clearance

Veri*Factu is a real-time (or near-real-time) reporting obligation. It requires businesses to use certified invoicing software that generates and transmits billing records to the Spanish Tax Agency (AEAT), including a hash chain linking each invoice to the previous one. Invoices must contain:

• The exact date and time of creation
• The invoice number
• A hash or footprint of the previous invoice record
• The identification code of the invoicing software
• A QR code allowing verification on the AEAT website, along with the phrase “Invoice verifiable on the STA website” or “VERIFACTU”

Importantly, Veri*Factu is not a clearance model. Invoices do not need to be approved by the AEAT before being issued. The obligation is to report, not to seek pre-authorisation.

Businesses already submitting data through Spain’s real-time reporting system (SII, Suministro Inmediato de Información) are exempt from Veri*Factu. The SII, which applies to large taxpayers and VAT groups, already achieves the same objective of near-real-time tax visibility.

Crea y Crece: The B2B E-Invoicing Mandate

Ley 18/2022 (Crea y Crece) established the legal framework for mandatory B2B e-invoicing. Where Veri*Factu is about tax reporting, Crea y Crece is about the structured exchange of invoices between businesses, a fundamentally different obligation.

Under the Crea y Crece mandate, businesses will be required to both issue and receive structured e-invoices for B2B transactions. Accepted formats are:

• Facturae (XML): Spain’s own established e-invoicing standard
• UBL (Universal Business Language): the international format used across the Peppol network
• CII (Cross Industry Invoice): the UN/CEFACT standard aligned with EN 16931

UBL and CII are particularly significant for multinationals, as they align with the Peppol framework being adopted across Europe and with the EN 16931 standard that underpins the EU’s ViDA reforms coming into effect from July 2030.

The Basque Country Exception: TicketBAI

Businesses with tax residency in the Basque Country (Bizkaia, Gipuzkoa, and Araba) and Navarra operate under a different framework. These regions have fiscal autonomy under Spanish law and have developed their own anti-fraud invoicing system: TicketBAI. This system is already mandatory across all three Basque provinces and replaces Veri*Factu entirely for in-scope businesses. If your organisation operates in these territories, your compliance path is governed by TicketBAI rather than the national Veri*Factu regulation.

The ViDA Connection

Spain’s e-invoicing mandate does not exist in isolation. It sits within a broader European transformation driven by the EU’s VAT in the Digital Age (ViDA) directive, formally adopted by the EU Council in March 2025. From 1 July 2030, all intra-EU B2B transactions will be required to use structured e-invoices based on EN 16931, and digital reporting obligations will apply to cross-border transactions.

For multinationals operating across multiple EU countries, this means that investments in compliant e-invoicing infrastructure today (structured formats, network connectivity, platform capability) serve both national mandates like Spain’s and the EU-level obligations arriving in 2030. Treating these as separate projects is both operationally inefficient and commercially risky.

Updated Timeline at a Glance

Note: The Ministerial Order activating the Crea y Crece B2B mandate dates was still pending publication as of June 2026. The October 2027 and October 2028 dates are based on the 12- and 24-month phasing built into the law from the date of the Order’s publication. Businesses should monitor the Official Gazette (BOE) for confirmation.

What Businesses Should Be Doing Now

The delays to Veri*Factu have given some businesses a false sense of comfort. In reality, 2027 is not far away, especially for organisations that need to adapt ERP systems, onboard suppliers, or work through procurement processes for new technology.

1. Confirm your Veri*Factu software situation

If you use an accounting or ERP system that generates invoices in Spain, check whether your vendor has obtained the required software certification. The obligation for vendors was July 2025; if your platform has not been updated, you may need to act before the January 2027 go-live.

2. Determine whether SII already covers you

Large Spanish taxpayers and VAT groups enrolled in the SII scheme are exempt from Veri*Factu. If your Spanish entity is already on SII, your real-time reporting obligations are met. The Crea y Crece B2B mandate is a separate matter and applies regardless.

3. Assess your structured invoice capability

The Crea y Crece mandate requires the exchange of structured invoices, not PDFs or email attachments. Review whether your current invoicing processes can produce and consume Facturae, UBL, or CII files. For most businesses, this will require changes to ERP configuration, accounts payable workflows, or both.

4. Map your Spanish supplier and customer ecosystem

E-invoicing is a two-sided obligation: you must be able to issue and receive compliant invoices. Audit your major trading partners in Spain to understand which ones are already operating on compliant platforms, which will need to upgrade, and what your timeline looks like for network readiness.

5. Plan for status messages

Both France’s mandate and Spain’s Crea y Crece framework are introducing mandatory invoice status messages: acknowledgement, acceptance, and rejection signals that travel back from buyers to suppliers. These are not currently standard in most businesses’ AP or AR workflows. Planning for status processing now will prevent operational disruption at go-live.

Important: All status updates must be communicated within 4 calendar days (excluding weekends and national holidays) from the date the event occurs. The status change must propagate from the buyer’s ERP to the e-invoicing platform within that window. In practice, many ERP configurations batch or delay status exports, meaning a status that changed on Monday may not reach the network for days, or in some cases not at all. Businesses should audit their ERP-to-platform integration now to confirm that status events are transmitted in near-real-time, not on a weekly batch cycle.

6. Treat Spain as part of your European compliance programme

If your organisation also faces mandates in France, Germany, Belgium, or other markets, the most efficient approach is a single platform strategy rather than country-by-country point solutions. The underlying standards (EN 16931, Peppol, UBL) are deliberately harmonised to support this.
