When a client chooses to use a verification service to manage and approve their contractors and suppliers, they have typically signed a contractual agreement with that service. That means that anyone performing work, or providing services and products must become a member of that service. It is also important to note that there are usually fees involved with these types of memberships. There are few exceptions but there are exceptions. These exceptions are commonly referred to as Variances. A client may grant a variance in situations where the compliance of strict qualifications may not be necessary.
