Part 8 Multi-Company

Multi-company management becomes important when one Odoo database is shared by multiple legal entities, branches, brands, or operating teams. A common example is a group company where one company sells goods to another internal company, or where a purchasing center buys products and resells them to several subsidiaries.

Odoo provides native multi-company rules for synchronizing invoices, bills, sales orders, and purchase orders between companies. These rules can reduce duplicate data entry and make internal trade easier to control, but they also require careful setup of companies, partners, products, taxes, journals, and user permissions.

In this part, we focus on inter-company purchasing. The goal is to help implementation users understand what Odoo can do natively, where the standard workflow stops, and how an extension can close practical gaps such as lot and serial number synchronization.
