Federal procurement managers face a common challenge: not just deciding what IT hardware to buy, but determining which contract vehicle to use to make the purchase. Between ITES-4H, NASA SEWP, and the GSA Schedule, each option offers distinct advantages—and potential limitations. Choosing the right path can save time, reduce procurement risk, and ensure compliance with federal mandates.
This article breaks down the differences between ITES-4H, SEWP, and GSA, compares their strengths and weaknesses, and offers practical guidance to help you choose the best vehicle for your next IT acquisition.
The Information Technology Enterprise Solutions – 4 Hardware (ITES-4H) contract is a $5 billion multiple-award, Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle. Managed by the Computer Hardware, Enterprise Software and Solutions (CHESS) program and awarded by the ACC-RI (Rock Island), ITES-4H was built for DOD, DOE and other federal buyers who need IT hardware delivered quickly and compliantly.
ITES-4H covers:
Only approved vendors can sell through ITES-4H, ensuring procurement managers work with trusted partners that meet security and performance standards.
NASA’s Solutions for Enterprise-Wide Procurement (SEWP) contract is a long-standing, governmentwide acquisition contract (GWAC) that has become one of the most widely used IT vehicles.
Unlike ITES-4H, which focuses narrowly on hardware, SEWP spans a broader range of products and services:
Civilian agencies often turn to SEWP because it is open to all federal buyers and offers wide flexibility. Its large vendor pool, however, can create complexity when narrowing down to the right supplier.
The General Services Administration (GSA) Multiple Award Schedule (MAS IT, formerly GSA Schedule 70) is the oldest and broadest of the three. It serves as a catalog for a wide variety of IT products and services.
GSA covers:
Its breadth makes GSA a flexible tool, but the trade-off is speed. With such a wide catalog and so many vendors, the procurement process can take longer, and buyers often need more time to evaluate offers.

The best contract vehicle depends on what you’re buying, who you are, and how fast you need it.
Across ITES-4H, SEWP, and GSA, small business vendors play a critical role in helping agencies achieve both mission success and contracting goals. Beyond socio-economic credit, the real value lies in agility, responsiveness, and specialized expertise.
