Mexican electronic invoicing system
Mexico's electronic invoicing requirements:
Mexico has one of the most sophisticated electronic invoicing systems in Latin America. Known locally as Comprobante Fiscal Digital por Internet, or simply CFDI, it was established in 2011, when it replaced the CFD or Comprobante Fiscal Digital. The difference between these two types of receipts/certificates that replaced the paper invoice is that the CFDI requires validation by an Authorized Certification Provider, also known as PAC. In some cases such validation can be done directly with the Tax Administration Service (SAT).
