Mexico is one of the leading countries in fiscal digitization and real-time validation thanks to the introduction of CFDI 4.0. However, according to the American Chamber de México, only 41.7% of Mexican companies have achieved digital maturity, although the global average is 70%. This means that most Mexican companies have not been able to digitize their fiscal operations. Therefore, we have worked to offer you a tool that not only allows you to manage your entire company from a single software, but to do so while complying with all your fiscal obligations.

The challenge of digitization and Odoo
The truth is that while the SAT increasingly promotes digitization, SMEs remain stuck in manual processes, human errors, rework, and endless spreadsheets with obsolete data that do not reflect the company's real health. Many times, this is due to the fear of losing historical data, not having the necessary tools to comply with obligations, or having to pay very high implementation fees to have software that adapts to their specific geographic needs.
Can I stamp my invoices? Can I create all the SAT reports? How complete is the Mexican localization of Odoo? How expensive is it?
Odoo knows that these are doubts that can halt your digitization, which is why we have created a series of modules to ensure that you continue complying with each of your fiscal obligations while optimizing your company's processes.
Essential modules for fiscal localization in Mexico
The Mexican localization of Odoo is composed of three main modules that you must install to comply with SAT requirements, in addition to six optional modules that you can install only if your company requires them.
México - Accounting
This is the basic module that installs the minimum necessary configurations for a company to operate in Mexico in compliance with SAT regulations.
Furthermore, it adds the chart of accounts with the accounts already labeled with the official grouped codes, in addition to all necessary taxes. The general minimum wage, the Unidad de Medida y Actualización (UMA), and the progressive tables of the Impuesto sobre la Renta (ISR) are up to date.
EDI for Mexico
This module includes all the requirements and functions to generate and validate electronic documents according to the documentation published by the SAT. Odoo connects with the Proveedores Autorizados de Certificación (PAC) so you can stamp your electronic invoices.
If for any reason you need to cancel an invoice, the cancellation acknowledgment of CFDI will be generated automatically. Starting from version 19, it is possible to select the bimonthly periodicity when creating global invoices, and you can also select which month you want to invoice (even past months).
Odoo Mexican Localization Reports
This module adds the necessary reports for Mexican companies: the income statement report (reporte de estado de resultados), which was created according to NIF-B3, and the balance sheet (balance general), which was created according to NIF-B6.
The income statement report helps to identify net earnings and the company's health, while the balance sheet reflects the company's current fiscal status. The optional modules include more reports for Mexican companies.
Additionally, every time you register a supplier invoice and mark it as paid, Odoo tracks that IVA, classifies your suppliers according to SAT regulations, and generates the DIOT report for you to just confirm and export.

Modules to expand your localization
These are the modules that expand the Mexican localization, but we recommend installing only if your company needs them:
EDI for Mexico (Advanced Features): To add the foreign trade complement to your invoices.
Mexico - Electronic Delivery Guide: To create the Carta Porte.
Odoo Mexican Localization for Stock and Pedimentos: To manage your pedimentos.
CFDI 4.0 Fields for Sales Orders: To comply with the new CFDI 4.0.
Mexican Localization for Point of Sale: Adds additional fields to Point of Sale to issue invoices for your customers' purchases.
Mexican Localization for E-commerce: Adds additional fields to your e-commerce store so your customers can receive their electronic purchase invoices.

Don't get left behind in the digital race
Odoo is business management software that allows you to manage every department of your company from a single place. Do you need to value your inventory? Accounting and Inventory connect so you always know how much is leaving and entering your shelves. Do you need to issue an electronic invoice? Sales and Accounting immediately share information between them so you can create the invoice for one of your sales.
This year's SAT Master Plan includes electronic audits. This means that today, accountants must have the necessary tools to access updated, real-time, and correct information. Having a spreadsheet with historical data, which is updated manually and depends on human control, is no longer enough.

All this, with the peace of mind that you will continue to comply with all SAT regulations without having to create a technical debt.
