Extra Partner Data and Padrón for Argentina

This module extends the standard contact (partner) form in Odoo with a button called "Update data from AFIP". It is meant for Argentine companies that need to keep customer and supplier records aligned with the official AFIP taxpayer registry (Padrón A5).

When a user opens a contact whose identification type is CUIT and clicks the button, Odoo connects to the AFIP web service using the credentials configured on the current company and retrieves the taxpayer's official data. The contact is then automatically updated with:

• the legal name (denominación)
• the street address and city (capitalised)
• the postal code
• whether the partner is a physical person or a company
• the AFIP VAT responsibility (for example IVA Responsable Inscripto, Responsable Monotributo, IVA Sujeto Exento, IVA No Alcanzado or Consumidor Final)
• the country (Argentina) and the province, with special spelling corrections for Neuquén and Córdoba

If the contact's identification type is not CUIT, the button does not query AFIP; instead the VAT responsibility is simply set to Consumidor Final.

The module touches the res.partner model and the AFIP responsibility type model, and adds a header button on the inherited partner form view. No new menus or reports are created.
