Spain Verifactu and B2B e-invoicing

Track Spain's Verifactu billing-software rules and expected B2B e-invoicing rollout while preparing EN 16931-ready invoice data.

What this covers

• Verifactu billing-software controls alongside the pending Crea y Crece B2B mandate.
• EN 16931-friendly invoice data prepared before exchange rules finalize.

Verifactu vs the B2B mandate — two different changes

Spain's e-invoicing story has two tracks that are easy to confuse. Verifactu is a billing-software integrity regime: invoicing software must produce tamper-evident invoice records (hash-chained, signed) and can optionally report them to the tax agency (AEAT) in near real time. It governs the software, not the invoice format you send customers. The separate B2B e-invoicing mandate under the Crea y Crece law requires structured invoice exchange between businesses — its technical regulation has been in development and applies once published, with phased deadlines.

For planning purposes: Verifactu is about the systems that produce invoices (in scope now, with compliance dates already in force for software makers and rolling out to users), while Crea y Crece is about how invoices travel between companies. A business may need both: software that meets Verifactu record-integrity rules and a channel that can exchange structured invoices once the mandate lands.

What structured data you should already be keeping

The safest preparation is format-agnostic: every invoice record should carry complete, machine-readable data — issuer and recipient tax IDs (NIF), unique sequential numbering, issue date, line-level VAT rates and amounts, and totals that reconcile. Under Verifactu the record also gets a hash and chain link; under a future B2B mandate the same data maps into UBL/CII/XML exchange formats.

If your current process is a PDF built in a document editor, the gap to close is upstream: capture the invoice as data first, then render the PDF as one view of it. That is exactly the discipline EN 16931 tooling enforces, which is why generating EN 16931-aligned invoices now is the lowest-risk preparation for whichever Spanish regulation lands next.

Watching the mandate clock without over-building

Crea y Crece deadlines start counting when the technical regulation is formally adopted: larger businesses (turnover above EUR 8 million) get roughly one year, everyone else roughly two. Rather than betting on a date, prepare the two capabilities every scenario needs — clean structured invoice data, and an exchange channel strategy (private platforms, facturae for public sector, or whatever the regulation accredits).

Meanwhile the B2G channel is already live: invoicing Spanish public administrations requires Facturae XML through the FACe platform. If any part of your revenue is public-sector, that obligation is current, not pending — and it exercises the same structured-data muscles the B2B mandate will use.
