Contract Overview

GSA’s OASIS+ is a suite of six government-wide, multiple award, indefinite delivery indefinite quantity (IDIQ) contracts designed to provide a broad range of professional services to all federal agencies. The six contracts—Total Small Business, WOSB, SDVOSB, 8(a), HUBZone, and Unrestricted—are nearly identical except for necessary differences due to size or socioeconomic restrictions. Companies may hold as many contracts as they are qualified for.

OASIS+ has no limit on the number of awards, and no ceiling on the contract value.

The scope of OASIS+ is currently organized into eight functional domains formed groups of related NAICS codes: Management & Advisory, Technical & Engineering, Research & Development, Intelligence Services, Environmental, Facilities, Logistics—all available on all contracts, and Enterprise Solutions—available only on the UNR contract.  

OASIS+ is a follow-on to the original OASIS contract and offers more flexibility for customers and more opportunities for small businesses. It has been designated as a Best-in-Class (BIC) contract by the Office of Management and Budget, making it a preferred government-wide solution

On June 17, 2025, GSA released an RFI seeking input on scoring factors for five new domains, which will be added to the program in Phase II:

  • Business Administration
  • Business Administration
  • Financial Services
  • Human Capital
  • Marketing & Public Relations
  • Social Services
 

Responses to the RFI are due by 5PM EDT July 8, 2025 and can only be submitted using the provided link.

 

Along with the RFI, GSA provides a list of the functional areas, sub areas, and NAICS codes for each of these domains. There is also an intake form for questions.

 

See the posting on SAM.gov here and the announcement on GSA’s Interact page here.

 

This is great news for industry because it indicates GSA is on track to reopen the solicitations in late FY25 or early FY26.

 

The reopening is expected to take three forms:

  • On-ramping will allow new offerors to get contracts.
  • Domain extension will allow existing contractors to broaden their scope to new domains.
  • Lateral springboarding will allow existing SB contractors to add other SB contracts for which they qualify (e.g., a Total SB contractor with a new 8(a) or SDVOSB certification).
