Recently Bloomberg Government (BGOV) hosted a meeting with contractors and the government focused on the importance of MACs to the Federal Government spending process. For fiscal 2014 BGOV reported one in four contract dollars flowed through a MAC with a total of $115 billion. BGOV also reported that MAC sales favored services over product purchases.
Starting in the early 1990s the government began to promote the use of MACS as a way to simplify their buying processes. Use for DoD acquisitions has grown steadily since them. More recently, Civilian agencies have also expanded use of MACs for their acquisitions based on their unique missions. This trend continues on the up swing as both the Air Force and Army have signed MOUs with GSA OASIS, a major new GWAC/ MAC.
