You can assign different levels of privileges to your team members. This will affect which actions they will be able to perform in the account.
NORMAL USER: Normal users are not able to create projects or tasks or view any data from other members. They are only able to track time and see their own activity reports.
PROJECT MANAGER: Project managers can create and manage projects and tasks. They cannot view billable amounts and costs unless otherwise selected in the settings. They are able to view reports only for projects they are assigned to and can delegate tasks to other members.
ADMINISTRATOR: Administrators have access to all functionalities and company-wide reports and can view all data. Their access is the same as of the account owner, except for managing the subscription. They are not able to change the subscription plan or edit the payment information.
You can additionally decide to show billable amounts to project managers AND show costs (calculated from their hourly rate) to all team members. Please go to General settings of Account admin to select this option.
