Verifactu is already mandatory
The Anti-Fraud Law requires all invoicing software to generate verifiable records with the AEAT. Operating without Verifactu entails fines of up to €50,000 per non-compliant system.
Full tax compliance for Spanish companies. We implement AEAT-certified Verifactu, automatic SII, TicketBAI for Euskadi and Navarra, FACe and factura-e — with direct integration into your management system.
Spanish tax legislation requires companies to adapt their invoicing systems. Non-compliance leads to penalties and reputational risks.
The Anti-Fraud Law requires all invoicing software to generate verifiable records with the AEAT. Operating without Verifactu entails fines of up to €50,000 per non-compliant system.
Companies subject to SII must submit VAT records within 4 days. A disconnected or manual system causes errors, delays and requests from the AEAT.
Each Basque regional treasury and Navarra has its own technical specifications. Incorrect implementation invalidates invoices and can result in differentiated regional penalties.
We cover all current electronic invoicing obligations in Spain, with official certifications and direct integration into your technology environment.
System approved by the Tax Agency. We generate the hash for each invoice, the event log and real-time submission to the AEAT verification system.
Automated submission of issued and received invoice ledgers to the AEAT within the legal deadline. No manual intervention, no transcription errors, with record reconciliation.
TicketBAI certification for Bizkaia, Gipuzkoa, Álava and Navarra. We generate the signed XML, the verification QR code and the connection to the corresponding regional treasury.
Issuance of electronic invoices to public administrations through the FACe general entry point, in factura-e format (XSig). Mandatory for suppliers to the Public Administration.
Electronic invoice exchange between companies in standard format. Reduction of administrative costs, greater traceability and preparation for the upcoming mandatory B2B requirement.
We connect all compliance systems to your current management platform. Without changing your ERP, without double data entry, with centralised auditable logs.
A structured process that minimises risk and maximises compliance certainty from day one.
We audit your current situation: which obligations apply to you (Verifactu, SII, TicketBAI), what system you use and what gaps exist with respect to current regulations.
We implement and configure the necessary compliance modules, integrating them with your existing ERP or invoicing system. Dedicated test environment included.
We validate the system in the AEAT and corresponding regional treasury test environments. We certify each integration before activating it in production.
We activate the system in production with support during the first days. Full documentation and training for the administrative team for day-to-day operations.
Since 2025, Verifactu affects all companies and self-employed individuals using invoicing software. SII applies to large companies and VAT groups. TicketBAI is mandatory in Euskadi and Navarra. Preparation is not optional.
The reform requires all invoicing programmes to incorporate Verifactu or equivalent systems. The AEAT publishes the official technical specification and carries out the approvals.
The adaptation deadlines for already-commercialised software have come into force. Do not wait until you receive a notice. Implement now and avoid penalties.
Verifactu is the verifiable invoicing system required by the AEAT for invoicing software since the reform of the Anti-Fraud Law (Ley 11/2021). It requires every invoice to be recorded and submitted to the AEAT with a unique verification code. It is mandatory for all companies and self-employed individuals using invoicing software from 2025, with staggered adaptation deadlines depending on the type of taxpayer and software used.
The SII (Immediate Supply of Information) requires companies with a turnover exceeding €6 million, VAT groups and voluntary registrants to submit VAT ledgers to the AEAT in near real time (4 working days). Verifactu, on the other hand, applies to invoicing software and guarantees the traceability and integrity of each issued invoice. Both obligations can coexist and are independent of each other.
TicketBAI (TBAI) is the mandatory tax system in Euskadi (Bizkaia, Gipuzkoa, Álava) and Navarra that requires invoicing software to generate a digitally signed XML file for each transaction and transmit it to the corresponding regional treasury. Each territory has its own technical specifications and timetables. At The BigTech Experience we are certified for all four territories.
The typical process ranges from 2 to 6 weeks. The initial regulatory diagnosis takes approximately one week. Configuration and integration with the existing ERP takes between 1 and 2 weeks. Testing and certification with the relevant authority requires another 1–2 weeks. Finally, the go-live phase with support closes the process. Projects with customised ERPs or multiple territories may require more time.
Yes. We develop both native integrations within our own solutions and API connectors for third-party ERPs. Before starting, we carry out a technical assessment of your current system. If your ERP has a documented API or allows exporting invoices in standard formats, we can integrate it. We also offer adapters for legacy solutions without an API.
