How can i mark a task as paid

is there a way to tag a task as paid? there is an open task, there is a completed task, but i want to tag the tasks that i already paid for the them to my supplier (the person who I asign the task to). is there any way? i tried to write a comment: paid on 14/9 but its generate email notification and im trying to limit the number of notifications ones get….

What about using custom fields or tags to mark your tasks “paid” @lilach_galor?
