auto_awesome What this module does
AI-generated from the code · Odoo 19.0Upload a Mexican tax situation certificate (CSF) PDF on a contact and Odoo automatically fills in the contact's RFC, name, address and state.
This module adds an "Upload CSF" button at the top of the contact form. Clicking it opens a small pop-up window where you select the PDF file of the Constancia de Situación Fiscal issued by the Mexican tax authority (SAT).
When you press Upload, Odoo reads the text of the PDF and updates the contact with the information it finds: - Tax ID (RFC) and legal name - Postal code, city and state - Street, exterior number, interior number and neighbourhood - Country is set to Mexico, and the state is matched to the Mexican state named in the document
The original PDF is also saved as an attachment on the contact, so you keep the proof on file. If the uploaded file is not a readable PDF, Odoo shows an error message and nothing is changed.
The button is available on the standard contact form, and the import pop-up can be used by contact managers. The module only touches the contact (res.partner) screen and does not create invoices or taxes by itself.
