Odoo is fundamentally open-source software, but is offered in two variants:
Community Edition
Open source and free to use, but offers only limited functionality.
Enterprise Edition
Extends the system with numerous modules and comfort functions, such as for accounting, helpdesk, mobile use or Studio customizations.
Especially for companies with more than 20 employees or a turnover of over 2 million euros, the Enterprise Edition is usually worthwhile, as it enables broader coverage of business processes.
Today's architecture was rebuilt in 2014 with the transition from TinyERP and OpenERP to Odoo and has been continuously developed since then.
In addition, Odoo is published annually in a new version with over 55 releases per year. Another factor is the over 12 million users worldwide as well as the strong partner and community structure that contributes to continuous improvement and enables economies of scale.
This question can hardly be answered in general terms. The costs for Odoo depend heavily on the respective project, such as company size, industry, modules used and the chosen infrastructure.
Those who opt for the Enterprise Edition pay license fees that are charged directly by Odoo. These are calculated monthly or annually and depend on the number of users, apps used and the type of integration.
In addition, there are costs for hosting, unless you run Odoo on your own server (On-Premise).
Compared to other providers such as SAP Business ByDesign, Oracle NetSuite or Microsoft Dynamics 365 Business Central, the total costs for licenses and hosting with Odoo are often 75-90% lower.
Yes. The system is designed for high user numbers, complex processes and international requirements. It supports over 100 national accounting standards, all currencies and many languages and can be flexibly adapted to very different business models thanks to its modular architecture.
Even companies with high requirements can use Odoo efficiently – often with significantly lower costs and less implementation effort than with traditional ERP systems.
