I want to use bare bone of EE without any paid modules, so what if I could buy EE on odoo.sh with one user and no app or one app, then I build my own app on top of it, sould I pay for extera users of my own module or, user count is only applies to the app's that I bought?
Thank you in advance
The whole solution will be custom made so, I don't need any standard apps but I need components like gantt charts from EE. Can you tell me more how can I get unlimited users for my custom made app? I need access to EE codebase and be able to develope and install apps on it.
You don't have access to the Odoo Enterprise source code unless you are an official partner.
Take a look at third-party apps that are available for Community Edition.
