Odoo SA is the Belgian software company that publishes the core Odoo platform — it maintains the core Community Edition (LGPLv3) and the Enterprise Edition (commercial). OpenEduCat is an independent company that publishes the OpenEduCat suite of education-specific modules (LGPLv3 open-source) that install on top of Odoo Community Edition. The OCA (Odoo Community Association) is a non-profit organisation that coordinates community-developed Odoo modules across many domains, including education — OCA publishes modules through the odoo/education GitHub organisation. The three are complementary: Odoo SA provides the substrate platform, OpenEduCat and OCA provide the education-specific extensions. The arrangement is similar to how many businesses use Odoo with industry-specific extensions from independent publishers.

No. OpenEduCat is built for and tested against Odoo Community Edition (the free open-source LGPLv3 version of Odoo). The full OpenEduCat education-module suite (admissions, attendance, fees, library, hostel, LMS, exam) runs on Community Edition without requiring Enterprise. Schools that already have an Odoo Enterprise subscription for other business reasons (typically when the school operates revenue-generating non-academic businesses requiring Enterprise-only features like accounting consolidation, advanced inventory, or specific commercial-Odoo features) can still install OpenEduCat alongside; OpenEduCat is compatible with both editions.

OpenEduCat maintains active releases across recent Odoo versions — Odoo 17, 18, and 19 each have a corresponding OpenEduCat release. Schools running older Odoo versions (16 and below) can upgrade per Odoo SA's version-migration tooling, with OpenEduCat's migration guide for the education modules. Per Odoo SA's release cycle, Odoo SA supports the most recent versions; running an older version means no upstream security patches. Best practice is to align the school deployment with a current Odoo version and the matching OpenEduCat release.

Licence cost is zero for the Community Edition route (Odoo Community + OpenEduCat + OCA modules are all open-source). Deployment cost varies: hosting ($5K-50K per year depending on scale), implementation and configuration ($30K-150K one-time depending on integration complexity), training and change management, and per-year platform upgrade. A school deploying with Odoo Enterprise adds the per-user Enterprise licence (typically $25-50 per user per month per Odoo SA's published pricing); most school deployments do not require Enterprise. The OpenEduCat partner network publishes per-module per-deployment pricing for institutions wanting a turn-key deployment.

PowerSchool and Ellucian are US K-12 / higher-ed-specialist vendors with deep market presence and per-learner SaaS pricing. Odoo-ERP-for-education with OpenEduCat is open-source with self-host or partner-host. PowerSchool / Ellucian typically have stronger K-12 integration with US-state-reporting feeds and deeper US-specific accreditation tooling; Odoo / OpenEduCat has stronger international flexibility (multi-currency, multi-language, multi-tax-jurisdiction inherited from the core Odoo platform) and lower per-learner TCO. The choice depends on institutional priorities — US-K-12 districts with strong state-reporting requirements often choose PowerSchool; international schools and higher-ed institutions with multi-campus complexity often choose Odoo / OpenEduCat.
