Its pricing model 1. Its pricing model: Its pricing model is often perceived as more transparent and potentially more affordable, especially for VSEs/SMEs. The Community (Open Source) version is free and already offers many features. The Enterprise version offers pricing per user per month, with a clear approach: no hidden costs or additional fees for each additional feature. 2. Ciel and Sage: Their pricing models can be more complex, with paid options for each user, each additional module, and each specific feature (e-VAT, e-SEPA, etc.). 3. Advantage of Odoo over Ciel and Sage: Costs can increase quickly depending on the size of the company and the required features.
