The "Project Phases" module enhances Odoo's project management capabilities by allowing users to divide projects into multiple phases. This structured approach facilitates better planning, execution, and monitoring of project progress.

After installing the module, navigate to the Project module. Within a project's form view, you'll find an option to add and manage different phases, enabling you to segment the project as needed.

No, third-party apps sold on Odoo Apps cannot be used with Odoo Online, unless they are data-only modules (that do not include any Python files).

The module requires the Project (project) and Discuss (mail) modules to be installed in your Odoo instance. Ensure these dependencies are met before installation.
