The Deactivate Membership workflow is meant to be run on a date decided by your association when, if Dues Orders have not yet been paid, you would like all members with outstanding Dues Orders of that Dues Cycle to be made Inactive and have a reinstatement fee applied to their order.
The Terminate Membership workflow is meant to be run on a date after a longer period of no payment and will terminate the membership. It will also add a reinstatement fee, if that has not already happened.
The Close Dues Cycle workflow is meant to be run if members are no longer allowed to pay for the renewal orders and need to reapply for membership. It will deactivate the membership and cancel the dues order.
The Deactivate and Terminate workflows add the reinstatement fee from the Reinstatement Fee field on the Dues schedules.
All three workflows can be found by going to the Dues Cycle in question and clicking the Workflow drop-down from the Ribbon Toolbar as seen in the image below:
