Mexico operates an entirely online fiscalization model through the CFDI system, where all invoices and receipts are electronically issued, digitally signed with SAT certificates, and validated in real time via authorized PAC providers. This fully digital approach, in place since 2011, ensures transparency, efficient tax compliance, and modernized administration without requiring fiscal devices or POS certification.

Mexico is one of the Latin American fiscal countries and is identified by the country code MX and its official currency, the Mexican Peso (MXN). As its tax authority, the country operates under the governance of the Servicio de Administración Tributaria (SAT), which is responsible for monitoring whether taxpayers meet all mandatory fiscal requirements.
In Mexico, the whole model of fiscalization is online-based, and it is facilitated through the CFDI (Comprobante Fiscal Digital por Internet) system. Unlike traditional fiscal models, there are no mandatory fiscal devices or POS certification requirements. Instead, businesses must issue electronic receipts and invoices (CFDIs), which are digitally signed with a certificate issued by SAT and validated in real time through authorized private providers known as PACs (Proveedores Autorizados de Certificación).
Mexico has been a pioneer in electronic invoicing and using more modern digitalization systems when compared to other countries worldwide. The process began in 2004 with the introduction of digital invoices, and in 2011, SAT launched the CFDI system, which became mandatory across sectors. Over time, it evolved through versions 3.3 and 4.0, with the latter being the currently valid standard.
The CFDI system requires that every transaction be fiscalized online at the moment of sale. All CFDIs are stored digitally and archived for at least five years, ensuring transparency and traceability intact.
This fiscalization model allows businesses to manage their tax obligations efficiently, with a strong focus on digital certificates, real-time validation, and secure archiving. By fully embracing a digital model for all transactions in scope, Mexico ensures better tax administration, combats fraud, and provides businesses with a streamlined, modernized way to comply with fiscal regulations.
