Odoo handles a term called "Fiscal localization" and refers to those modules that allow Odoo to comply with the mandatory guidelines established by the tax authority of a country. In the case of Mexico, the fiscal authority is the SAT.

An important point is that localizations only work on Odoo Enterprise.

The magic happens in the accounting module of Odoo, which has a default configuration that contains:

• A chart of accounts defined by the tax body.
  

• The tax catalog with its percentages.
  

• Tax positions.
  

• Legal declarations.
  

• Flows of some features of Odoo that are affected by localization:
  

1. Specific certificates.
   

2. Electronic billing.
   

The Mexican localization or also known as OML (Odoo Mexico Localization) are the modules that allow Odoo to comply with the guidelines established by the SAT.

As of 2019, the Odoo company maintains the Mexican localization, its improvements and support, this applies to the current version of Odoo and 2 previous versions, that is, V15, V14 and V13 of Odoo Enterprise.

The native settings and functionalities of the Mexican localization are:

1. The configuration of the entire accounting module.

1.1 Adjustment and configuration of taxes.

1.1.1 General purchase taxes.

1.1.2 Import Taxes.

1.1.3 Non-creditable taxes.

1.1.4 Sales taxes.

1.1.5 IEPS taxes, among others.

1.2 Catalog of SAT codes for billable products to customers.

1.3 Catalog of the SAT grouping code for accounting classification.

2. The electronic invoicing process.

2.1 Electronic billing to customers.

2.2 Payment add-ons.

2.3 Cancellation of invoices.

3. The delivery of obligatory reports (XML Reports - SAT) that the SAT requests monthly or periodically).

3.1 General Balance.

3.2 Chart of accounts.

3.3 DIOT.

4. The localization contemplates the updates made by the fiscal entity to the electronic invoicing methods.

The extended OML is a private project, developed and maintained by Vauxoo, to extend the native functionalities of Odoo around the Mexican legality.

That is to say, the project starts from the accounting and operational base of Odoo in its accounting base modules and continues with new modules made by Vauxoo that aims to extend the functionalities that apply to the business models for which we work.
