Notice - Mexican e-Invoicing Requirements and EDI Requirements

In May 2009 the Mexican government will change the way companies can send paper invoices to customers. Current regulations allow paper invoicing using government-issued invoices or customer-generated invoices. But with the new regulations, instead of being able to print their own invoices, companies using paper invoicing will now be required to obtain pre-printed invoice forms certified by the Servicio de Administracion Tributaria (SAT) or adopt a solution to send digitally signed invoices electronically to domestic and international customers.
