Odoo Community is free and open source, covering core business modules without official support. Odoo Enterprise adds premium applications, the Odoo Studio customisation tool, official support, and hosting on Odoo.sh for AUD $34.40/user/month. Community customisations require manual upgrades with each new version, creating technical debt risk. Enterprise's Studio customisations are upgrade-safe. For most businesses evaluating Odoo seriously, Enterprise is the relevant comparison against NetSuite.
