General Services Administration

The General Services Administration (GSA) is an independent agency of the United States government established in 1949 to help manage and support the basic functioning of federal agencies. The GSA supplies products and communications for U.S. government offices, provides transportation, office space, building services, and property management to federal employees, agencies, and develops government-wide cost-minimizing policies and other management tasks.
The GSA employs about 12,000 federal workers. It has an annual operating budget of roughly $33 billion and oversees $66 billion of procurement annually.
