®Spain e-invoicing and Verifactu software compliance
Spain has two tracks: Verifactu sets rules your billing software itself must meet, and the Crea y Crece law brings mandatory B2B e-invoicing with invoice status reporting. We get your billing software Verifactu-ready and prepared for structured B2B exchange (FacturaE, UBL, CII).

What is Verifactu & Crea y Crece B2B e-invoicing in Spain?
Spain is approaching e-invoicing from two directions. Verifactu is a set of requirements for the billing software itself: records must be tamper-evident, chained with hashes, and, in the Verifactu mode, reportable to the tax agency (AEAT). Its effects are deferred to 2027, and businesses already in the SII real-time VAT system are largely outside its scope.
The second track is the Crea y Crece law (Law 18/2022), which makes structured B2B e-invoicing mandatory between companies and professionals established in Spain, with the implementing Royal Decree approved in 2026. Accepted formats include FacturaE, UBL, and CII, and businesses must also report the status of each invoice (accepted, paid, and so on). Reported timing is large businesses first and all others later, but the exact start dates depend on a ministerial order still to be published.
We prepare your software for both: Verifactu-compliant record-keeping now, and structured B2B exchange with status messaging when Crea y Crece lands.
A complete Spain integration.
Whether you run an off-the-shelf ERP, a cloud accounting app, or a POS you built in-house, we make it comply with Verifactu & Crea y Crece B2B e-invoicing, end to end.
Verifactu-compliant records
We make your billing software keep tamper-evident, hash-chained records that meet the Verifactu requirements.
AEAT reporting (Verifactu mode)
Where you opt into the Verifactu mode, records are reported to the AEAT as required.
Structured format support
We add FacturaE, UBL, and CII so you are ready for Crea y Crece B2B exchange.
Invoice status messaging
We implement the required status updates (accepted, paid, and so on) back to the system.
B2B exchange
We connect you to the exchange channel Crea y Crece settles on, including Peppol where relevant.
ERP / billing integration
All of this runs inside your existing billing or ERP software.
The Spain compliance timeline.
Starting before enforcement means a calm cutover. Waiting means doing it under pressure.
Verifactu effects
Verifactu billing-software rules take effect.
Crea y Crece B2B mandate
Mandatory B2B e-invoicing phases in, reported as large businesses first.
Exact start dates
Crea y Crece start dates depend on a ministerial order still to be published. Confirm with the AEAT.
Who the Verifactu & Crea y Crece B2B e-invoicing rules affect.
Businesses using billing software
Verifactu sets rules the software must meet, so vendors and users of billing software need a compliant system.
Companies and professionals (B2B)
Crea y Crece covers domestic B2B transactions between companies and professionals established in Spain.
Businesses outside SII
Those not already in the SII real-time VAT system are the main audience for Verifactu.
Dates and thresholds change, and scope depends on your exact situation. Treat this page as a starting point, confirm the detail with the Agencia Tributaria (AEAT) and Ministry of Economy, and tell us what you run today, we will tell you plainly what an integration would involve.
Built into the software you already run.
We make your billing software Verifactu-ready now, so your records meet the requirements, and we prepare you for Crea y Crece B2B exchange with FacturaE, UBL, or CII and invoice status messaging. If your system cannot be adapted, we build one that can.
The two tracks have different timelines, so the sensible move is to fix the software-compliance piece first and layer B2B exchange on when the dates firm up.
