Odoo, one of the largest and finest ERP solutions, has two versions: Community and Enterprise. Community version is fully open-source, while Enterprise version is licensed. Before 2015, only Odoo Community version was available. Odoo Enterprise was introduced in 2015 with new modules and features. The distinction between two versions grew in Odoo 12th edition. These distinctions can be observed in these features: Modules, Bugfixes, Hosting Options, and Price Comparisons.
About modules, large scale work is done on Odoo Enterprise, i.e. IP-addresses-lead-generation, multi-website management, document management, studio, and IoT (Internet of Things). Odoo Enterprise version operates accurately in e-commerce, accounting, and manufacturing. It provides shipping integrations, Quality Control, IoT integration maintenance as well as it is connected to eBay.
Furthermore, Odoo Community has basic-level customization and lesser GUI (Graphic User Interface) designing options. It also has less sales management, project management, e-commerce, inventory, and manufacturing options.
About bugfixes, Odoo Enterprise offers support services to its customers for bugs and other network security problems, while Odoo Community does not have this attribute.
About hosting options, Odoo Community and Odoo Enterprise differ too. Odoo Community offers hosting options to the host himself, and he can easily control and customize the content. It provides on-premise and cloud hosting. Along with on-premise and cloud hosting, Odoo Enterprise also gives access to cloud hosting (in Odoo.sh) and a non-customizable SaaS (Software as a Service).
About price comparisons, Odoo Community is less expensive than Odoo Enterprise because one has to pay the license fees in the latter. Also, Odoo Enterprise offers more functions and modules, and therefore, its price is higher. If the same features are demanded and used on Odoo Community, it will be even more costly than Odoo Enterprise.
