In current version the basis for access and invoicing is users defined in the user setup. In a project when testers are involved now and then, the administrator must manually remove the users to have control of the costs. When the users is supposed to do testing activities later, the admin must then manually add all users. This is very time consuming in big projects. However, it should be possible to set a user inactive by changing a status that will prevent the user from having access to the project and also will exclude this user from the payment.
