Apart from the User Story status "ToDo"/"In Progress"/"Completed"/"
Accepted", create one more: "Billed" or perhaps "Processed". Better where, if i could lable this myselves, but Billled would be great. I work with a freelancer and we use EasyBacklog as a our main tool. With this new label it's easyer to bill/pay freelancers.
