The Spanish (Veri*factu) and Basque (TicketBAI) Cash Security Regulation is being introduced to the market right now. With different due-dates, the Spanish financial authorities (Agencia Estatal de Administración Tributaria and Haciendas Forales) are requiring that your PoS-Solution complies with certain organizational and technical requirements. These requirements are forming the basis for a tamper-proof operation of cash registers in Spain, including the Basque Country.

By using SIGN ES, you will be complying with the legal regulations as soon as the final version is released.

SIGN ES is a platform-independent and software-only solution. SIGN ES is a RESTful API. The only thing you need in order to integrate SIGN ES is a stable internet connection.

About TicketBAI

TicketBAI is a joint project of the Basque Government and the regional tax administrations of the three Basque provinces: Araba, Gipuzkoa and Bizkaia. TicketBAI is a software-based fiscalization system that was designed to prevent manipulation of tax-related information and prevent fraud.

TicketBAI applies to:

  • All natural and legal persons and entities that carry out an economic activity that falls within the jurisdiction of the Basque Tax Administration in personal tax income or society income, as established in the Economic Agreement with the Autonomous Community of the Basque Country (Law 12/2002, of May 23 (Spanish only)).

  • The supply of goods and the provision of services, in B2B and B2C operations.

  • In-store and online sales.

  • Paper and/or electronic invoices issued.

The basic process of TicketBAI compliance consists of:

1) The billing or POS system is equipped with a TicketBAI guarantor software.

2) An XML file or “TicketBAI File” is generated and electronically signed using a digital certificate. This file will contain the corresponding TicketBAI footprints: chaining to the previously generated file and information about the software used.

3) The XML Files are automatically sent to the corresponding tax authorities.

4) The issued invoice contains the TicketBAI ID code and QR code.


Once you integrate SIGN ES API, you will already be compliant with TicketBAI.
