To start working on a project in Bitrix24, create a workgroup and invite only the employees involved in the project. Assign tasks and upload necessary files. Workgroups store all data, tasks, files, and messages in one place, allowing you to track task completion within the workgroup.

If you need to specify exact project dates, select the Project type of workgroup.
Create workgroups and projects

A project is a special type of workgroup. The main difference is the connection between project dates and task deadlines. Project task deadlines cannot be set or changed outside of project dates.
Difference between a workgroup and a project

Any employee can create a new workgroup or project. The number of workgroups (projects) is unlimited for all Bitrix24 plans.
