AI Summary

Odoo's modular architecture makes it adaptable for e-invoicing, but it does not ship with full mandatory format support out of the box. For countries like France (Factur-X) and Italy (FatturaPA), businesses typically need a third-party module from the Odoo Apps store or custom development.

Data Mapping and Field Implications

Odoo stores invoice data in a Python object model. Mapping to EN 16931 XML requires generating XML from Python using the lxml library or similar. The QWeb report engine generates the PDF component for hybrid formats.

Export and Transmission Considerations

Odoo supports direct API integration for sending invoices. For Peppol, use a third-party access point module or integrate via Odoo's webhook/API capabilities.

Archive and Retention

Odoo stores all invoices in its database. For long-term legal retention, export to external storage (PDF/A, XML) and integrate with a document archive solution.

Certified Add-ons and Integrations

The following add-ons and integrations have been documented for use with Odoo. Verify current certification status with the add-on provider before implementation.
