Mexico has been changing its invoicing procedures since year 2004. In that year the rules for electronic invoicing were published. Since then many companies have been changing to this new model. Pegaso Tecnología has been market leader on this field since 2006.

How Electronic Invoice works in México

The electronic invoice is the digital representation of a type of digital invoices (CFD), which is attached to the safety standards set by the SAT in Annex 20 of the Miscellaneous Tax Resolution. The invoice can be generated, transmitted and protected by electronic means. Each electronic invoice issued a stamp with digital (electronic signature) which confirms their origin and gives validity to the SAT, an original string that serves as a summary of the contents of the bill, and a sheet indicating the number of transaction .

What do I need to have in order to make electronic invoices in México?

Since 2011 the model has changed. Now you need to have the Advanced Electronic Signature (FIEL = Firma electrónica avanzada) and the Digital seal certificate (CSD = Certificado de Sello Digital). Both need to be processed using the program "SOLCEDI" that you can download from the SAT Page. To generate the FIEL, you need to download the SOLCEDI program, fill all the information they ask about your TAX registration in México, and you will obtain a set of files. Then you must ask for a date directly on the SAT office, take those files with you, and they will validate them. Once validated you will be able to use them not only for electronic invoice, but to pay taxes, and all your interaction with the SAT. When you have your FIEL, then using the SOLCEDI system you can process your CSD. The program will give you a new set of files, but this time you don´t need to go to your SAT Office, you will have to enter to the SAT Page and look for the "Certisat" Page. In that web page you will validate and download the necessary files for your CSD. Don´t worry, if you need the service we can help you all the way, so you can obtain the necessary files to operate the system Once we have the files, then we should register you on our system to allow you making electronic invoices. You can have two different kinds of services with us:

What are they? The Addenda are additional non-tax information can be added to an electronic invoice within the XML file and can be or cannot be, part of the printed version (the PDF file). There are two types of Addenda:

The Issuer Addenda. If you have an invoice including tax data, for example, vendor name, the number of purchase order or production order, the license plates of a vehicle, means of transport which moves the goods sold, the name of a patient, and so on, and you want to include this information into the electronic bill, then it should be included in the addenda section of the XML file. If you only add this data to the printed representation of the voucher, the clients you send the electronic invoice files XML, will not receive this information.

The Customer or Receiver Addenda. These are intended to automate the reception of electronic invoices. Several companies have successfully implemented their use and ask their suppliers to include them. In our country, many companies have standardized system GS1México (Before AMECE Mexican Association for Electronic Commerce Standards), although this practice is not mandatory, each company has its own definitions of Addenda.

Does Addendas have a cost?

In our case, the addendas have an additional cost, and we make sure that the added  addendas meet all the standards requested by the clients, we test for SLOS performance against client systems  that are installed on each system independently If you change the print format to suit the required data in it.
