ClickUp is built around Workspaces. When you first sign up, you'll either be creating a new one, or joining an existing one.
Workspaces are large organization units like companies, enterprises, small businesses and agencies. Sometimes larger companies choose to use multiple Workspaces for their organization. However, we don’t usually recommend that because ClickUp is separated at the Workspace level.
These are designed to let you completely customize different areas of work. Each Space allows flexible features and workflow settings. Customization at the Space level allows you to use Spaces for simple things (like content) and complex things (like engineering) in the same Workspace. We often see Spaces used to house departments or high-level initiatives.
Lists contain tasks and views, and Folders let you organize your Lists. Folders can also contain views and allow you to see tasks across all Lists within. With List Info you can even add conversations, owners, priority, dates, and other information about the project you’re working on.
Tasks are where work actually gets done. They contain descriptions, conversations, and all activity history. Tasks inherit traits from Spaces, and are organized within a specific List. Tasks also can contain subtasks, assigned comments, and checklists.
