If you have built a deliverable with several tasks and you will repeat this deliverable again - either for the same project, or a new project/client - you can easily duplicate it.
Click "Duplicate" just above the status bar in the chosen deliverable.
Your deliverable name (plus "Copy of" so you can differentiate the new deliverable), client, project, fee structure if the deliverable has its own price, tasks, assignee, and due date will all be copied to the new deliverable. The feed and time worked will not be copied.
To assign the duplicated deliverable to a new project or client, simply use the drop down boxes to move it to the correct project or client.
