Odoo is a suite of business applications. The software is designed with a perfect modular approach and allows the user to start with one application and keep on adding new applications when the business grows. All the applications are installed later and will be integrated by default.
Odoo focuses on a great user experience for the first run, and it keeps the business flow as simple as possible. A user can start using it confidently, but on the first run, you may not get all the features; however, additional features can be activated once you install the new application.
Let's try to install the Sales app and enable a pricelist for a product based on specific customer segments.
