From inception, Odoo S.A (formerly OpenERP S.A) has released the core software as open source.[1] Since the V9.0 release, the company has transitioned to an open core model, which provides subscription-based proprietary enterprise software and cloud-hosted software as a service, in addition to the open source version. In 2013, the not-for-profit Odoo Community Association was formed to promote the widespread use of Odoo and to support the collaborative development of Odoo features.
