General Services Administration (GSA)

How It Works

The General Services Administration (GSA) is the federal government's central procurement, real estate, and technology services agency, established in 1949 and employing roughly 12,000 staff with an operating budget of approximately $11 billion per year, funded largely through working capital funds and user fees rather than direct appropriations. GSA's three primary service lines are: (1) the Federal Acquisition Service (FAS), which operates the GSA Schedule (Multiple Award Schedule) program with roughly $45 billion in annual sales across 11,000 contract holders, plus specialized vehicles like OASIS (professional services), Alliant 2 ($50 billion IT services ceiling), and various e-commerce and reverse-auction platforms; (2) the Public Buildings Service (PBS), which manages over 370 million square feet of government-owned and leased office and courthouse space across 8,600 buildings, making it one of the largest real estate portfolios in the world; and (3) Technology Transformation Services (TTS), which runs 18F, Login.gov, Cloud.gov, and the USDS-adjacent modernization work. For contractors, getting on the GSA Schedule is often the first practical step to federal market entry. GSA also runs SAM.gov, USASpending.gov, Challenge.gov, and IT Dashboard, infrastructure for the federal government's procurement and spending transparency ecosystem. GSA has been a recurring target of reform efforts, including the 2017 reorganization that consolidated 18 separate categories into Category Management, and ongoing DOGE-era reviews of real estate utilization and Schedule pricing practices. GSA also operates Fleet (the federal vehicle fleet of over 225,000 vehicles leased to agencies), SmartPay (the government purchase card program processing over $25 billion in annual transactions), and the Telecom and IT Services programs like Enterprise Infrastructure Solutions (EIS), a $50 billion vehicle replacing the legacy Networx program.
