Freedcamp is a project management service that allows users to work on multiple projects together.    

When creating a project, set deadlines at once, attach the necessary materials, as well as prioritize and assign employees to work on projects and select those responsible for implementation.

I remember to divide each project into tasks and delegate separate tasks for different employees so that several people work on the same project at once - this will speed up the process.

You can organize comments under projects so that everyone can express his or her opinion or direct the other person in the right direction. The manager can also express his or her opinion in comments. The service also has a "Discussion Board", where all projects can be discussed.

All plans and tasks can be arranged in a graphical form for greater visibility, for example, in the form of Gantt charts. To do it, you will need to install a special add-on.

The service also has a built-in billing system, so you don't have to install separate software.
