One Acquisition Solution for Integrated Services Plus - Total Small Business (OASIS+SB)

GSA Federal Acquisition Service established the One Acquisition Solution for Integrated Services Plus - Total Small Business (OASIS+SB) Master IDIQ on December 19, 2024, as a governmentwide vehicle fully set aside for small businesses, with ordering authority extending through December 18, 2029.

The vehicle carries a shared ceiling of $999,999,999,999 and has generated 151 task orders totaling $2.61 billion in combined potential value since the first award on March 1, 2025. As of August 3, 2026, $421.5 million (16 percent) has been obligated across 57 distinct customer agencies and 109 prime contractors, indicating substantial remaining capacity. Ordering momentum accelerated in 2025 with 96 awards but moderated to 55 in 2026 through August, suggesting a possible seasonal or resource-driven slowdown. The vehicle remains active with over three years of ordering authority remaining.

Task orders span seven functional domains: Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental Services, Facilities, and Logistics. Recent awards include diverse scopes — transnational financial analytics support ($80.4 million ceiling), F-16 engineering and administrative services ($125.7 million ceiling), armament directorate support ($767.7 million ceiling), military communications and positioning support ($147.8 million ceiling), and smaller specialized contracts for janitorial, carpentry, and security services. Pricing structures vary across firm fixed price, labor hours, time and materials, cost-plus-fixed-fee, and fixed-price level-of-effort models, with typical durations ranging from one to five-plus years.

Competition concentrates among a small set of established primes. Credence Management Solutions, Bryce Space and Technology, and MLT Systems lead by combined potential value; Bryce holds the most individual task orders. However, the long tail is substantial — the top five primes account for roughly 11 percent of combined potential value, with 104 additional contractors holding awards, suggesting a fragmented competitive landscape accessible to emerging vendors.

Customer concentration centers on the Department of the Air Force, which placed 33 orders (22 percent) valued at $350.7 million combined potential, with Air Combat Command and Space Command as the largest sub-organizational customers. The Department of Defense dominates overall, though Department of Health and Human Services, Department of Homeland Security, and civilian agencies hold meaningful order volume. About 85 percent of task orders carry the Total Small Business set-aside designation; the remainder split among unrestricted (14 percent) and 8(a) sole-source or competitive awards (1 percent each).

Task-order values span from sub-$100,000 service orders to nine-figure awards, with most task orders ranging from $2 million to $30 million in ceiling value. No minimum guarantee obligation beyond the standard FAR clause appears; the vehicle carries a 0.15 percent Contract Access Fee on all orders. Geographic performance concentrates at federal facilities, military bases, and contractor sites across CONUS and select OCONUS locations, particularly supporting Air Force and Army operations.
