Open Source CRM manages role based user permissions with simple rules. Admins create roles like sales, support, or manager. Each role gets access to specific pages and actions. Users only see data linked to their role. This lowers errors and protects records. Edit, view, and delete rights stay controlled. Testing checks that roles work as planned. Open Source CRM also allows custom roles as teams grow. This setup improves security, supports compliance, and helps users focus on daily tasks without confusion across teams and workflows in growing organizations today.
