Implementing Mexico localization in Odoo 18 is crucial for businesses operating in Mexico to ensure compliance with local accounting standards and electronic invoicing regulations. This guide provides a comprehensive overview of setting up and utilizing the Mexican localization features in Odoo 18.
Understanding Mexico Localization in Odoo 18
Odoo's Mexican localization modules are designed to align with the specifications of the Servicio de Administración Tributaria (SAT), Mexico's tax authority. These modules facilitate the generation of electronic invoices (CFDI version 4.0), mandatory since January 1, 2022, and include essential accounting reports like the DIOT for foreign trade.
Prerequisites for Implementation
Before configuring the Mexican localization in Odoo 18, ensure the following:
SAT Registration: Your company must be registered with the SAT and possess a valid Registro Federal de Contribuyentes (RFC).
Digital Seal Certificate (CSD): Obtain a valid CSD, necessary for signing electronic documents.
Authorized Certification Provider (PAC): Choose a PAC authorized by the SAT. Odoo integrates with providers like Solución Factible, Quadrum (formerly Finkok), and SW Sapien - Smarter Web.
Odoo Proficiency: Familiarize yourself with Odoo's billing, sales, and accounting functionalities to effectively implement the localization.
Installing the Mexican Localization Modules
To equip your Odoo 18 system with Mexican localization features, install the following modules:
Mexico - Accounting (l10n_mx): Introduces the default fiscal localization package, including the chart of accounts and common taxes based on SAT's account grouping code.
EDI for Mexico (l10n_mx_edi): Enables the generation and validation of electronic documents in line with SAT's technical specifications, allowing the issuance of invoices and payment complements.
EDI v4.0 for Mexico (l10n_mx_edi_40): Ensures XML documents meet the specifications of CFDI 4.0.
Odoo Mexican Localization Reports (l10n_mx_reports): Provides necessary accounting reports for Mexico’s electronic accounting, such as the DIOT.
When setting up a new database and selecting Mexico as the country, Odoo automatically installs the l10n_mx, l10n_mx_edi, and l10n_mx_edi_40 modules.
Configuring Your Company in Odoo 18
After installing the necessary modules, configure your company details:
Navigate to Settings > General Settings > Companies and select Update Info under your company name.
Fill in the complete address, including ZIP code, state, country, and RFC (VAT number). Ensure the company name matches the business name registered with the SAT, excluding legal entity abbreviations.
Go to Settings > Accounting > Electronic Invoicing (MX) > Fiscal Regime and select the applicable regime from the drop-down list.
Managing Contacts
For invoicing purposes, ensure each contact has:
A complete address with ZIP code, state, country, and RFC.
A business name matching the SAT registration.
The correct fiscal regime specified in the MX EDI tab.
This meticulous setup ensures compliance with SAT requirements.
Electronic Invoicing Workflow
Odoo 18 streamlines the electronic invoicing process as follows:
Creating Customer Invoices: Generate a customer invoice using the standard workflow. While in draft mode, you can modify details like the payment method or usage as required by the customer.
Confirming Invoices: Upon confirmation, Odoo processes the invoice asynchronously through the CFDI (4.0) e-invoicing service. The system sends the document to the SAT for signing and, once validated, attaches the XML file to the invoice.
Handling Credit Notes: Credit notes are classified as document type "E" (Egreso) and must reference the original invoice's fiscal folio. Utilize the Add Credit Note feature from the invoice to ensure proper linkage.
Payment Policies: Odoo supports two payment policies:
PUE (Pago en una Sola Exhibición): Payment in a single installment.
PPD (Pago en Parcialidades o Diferido): Payment in installments or deferred.
The due date or payment terms determine the applicable policy.
Cancelling Electronic Invoices
As of January 1, 2022, cancelling electronic invoices requires specifying a cancellation reason and, if more than 24 hours have passed since issuance, obtaining client approval. To cancel an invoice due to errors, create a new invoice referencing the original, then request cancellation of the erroneous invoice.
Benefits of Implementing Mexico Localization in Odoo 18
Adopting the Mexican localization in Odoo 18 offers several advantages:
Regulatory Compliance: Ensures adherence to SAT's electronic invoicing mandates and accounting standards.
Secure Document Storage: Provides tamper-proof archiving of invoices, facilitating easy retrieval during audits.
Conclusion
Implementing Mexico localization in Odoo 18 is essential for businesses aiming to comply with Mexican tax laws and streamline accounting processes. By properly configuring localization modules, companies can efficiently manage electronic invoicing, tax reporting, and financial transactions while ensuring compliance with SAT regulations.
