Projects are groups of tasks, tickets, events and more. Use a project for a larger goal task with sub-tasks for an action someone on your team needs to take in order to achieve that goal.
Tasks are the basic objects around which many processes in AccuTask are centered. Tasks can be grouped by categories and drag/drop to position them as needed. In addition you can set recurring tasks and many identifiers like the priority and status. Tasks can be assigned to multiple users and teams.
