GSA Overhauls MAS Program, New SINs in Old SINs out

As part of its Multiple Awards Schedule (MAS) refresh taking effect this month, the General Services Administration (GSA) introduces more defined subcategories under information technology contracting. (MeriTalk April 1,2025)

A new GSA document reveals that starting in April, Special Item Numbers (SINs) under IT contracting will become more specific with the addition of artificial intelligence, cloud, and cybersecurity-related subcategories. These SINs help Federal agencies identify and acquire products and services from pre-approved vendors. (ibid)

One new subgroup, “Incident Handling and Event Management,” falls under the “Highly Adaptive Cybersecurity Services” subcategory.(ibid)

GSA also expands cloud-related services by introducing the “Cloud Services Subcategory,” which includes all IT professional services that support the Government’s adoption of, migration to, or governance and management of cloud computing.(ibid)

Cloud-related vendors now provide services such as legacy system migrations, development operations, cloud-native application development, cloud solution management and governance, and cloud solution assessments.(ibid)

As part of the IT contracting expansion, GSA retires 31 SINs to support its MAS program overhaul, which it announced on March 24.(ibid)

“The retirement of these SINs supports the FAS initiative to optimize the Multiple Award Schedule Program by removing items with insufficient market demand or high administrative costs that outweigh procurement benefits, making them unsuitable for the MAS program,” GSA stated. “Furthermore, many of these items remain available through other procurement channels.”(ibid)

GSA plans to retire 11 SINs in the professional services category, seven in the office management category, and one in the Scientific Management and Solutions category.(ibid)

In addition to the MAS overhaul, President Donald Trump signed an executive order earlier this month to consolidate Federal contracting under GSA, including IT contracts.(ibid)
