Beginning with Odoo 9, Odoo SA started releasing two versions of Odoo—a Community Edition and an Enterprise Edition. The Community Edition is free, open source, and primarily supported by the Odoo community. Odoo Enterprise, while also open source, requires a license based on the number of users. More recently, Odoo pricing for the Enterprise version has been varied depending on region.
Odoo Enterprise offers an alternative (and arguably better) user interface. Additionally, there is better functionality in some applications, as well as support by SA and, perhaps most critical of all, migration to the new releases of Odoo. More information on the differences between Odoo Community and Odoo Enterprise Editions is available in Chapter 16, Comparative Analysis of Community versus Enterprise Editions.
This book primarily targets the Community Edition of Odoo.
