OASIS+ Phase II Is Coming

The time to prepare is now.

GSA has announced plans to release OASIS+ Phase II in January, marking the next major expansion of one of the government’s most important professional services contract vehicles. Phase II introduces new domains and reinforces GSA’s move toward a continuously open acquisition model—changing how and when companies can compete.

A Best-in-Class Contract Vehicle Prioritized for Governmentwide Use

OASIS+ is designated as a Best-in-Class (BIC) contract, making it a preferred solution for federal agencies seeking comprehensive professional services. As GSA continues to emphasize procurement consolidation and streamlined acquisition, OASIS+ is being positioned as a go-to vehicle for complex, mission-critical requirements.  

For professional services firms, this means OASIS+ is increasingly central to long-term federal growth strategies.

A Major Shift: Continuously Open Solicitations

OASIS+ represents a significant departure from the previous OASIS model. Instead of a single, high-pressure submission window, GSA is moving OASIS+ to a continuously open structure.

This shift allows:

  • Ongoing proposal submissions after the solicitation re-opens

  • Rolling awards over time

  • New opportunities for firms that were not ready during earlier phases

Readiness and positioning now can directly impact how quickly a company can compete and win.

Understanding OASIS+

OASIS+ is a suite of governmentwide multiple-award IDIQ contracts designed to provide federal agencies with access to a wide range of professional services.

Six IDIQs

  • Total Small Business (SB)

  • SBA-Certified 8(a) Small Business

  • SBA-Certified HUBZone Small Business

  • SBA-Certified Service-Disabled Veteran-Owned Small Business (SDVOSB)

  • SBA-Certified Women-Owned Small Business (WOSB)

  • Unrestricted (UR)

Thirteen Service Domains

OASIS+ spans 13 professional services domains, including:

  • Management and Advisory
  • Technical and Engineering
  • Research and Development
  • Environmental
  • Intelligence Services
  • Enterprise Solutions
  • Facilities Services
  • Logistics
  • Business Administration
  • Financial Services
  • Human Capital
  • Marketing and Public Relations
  • Social Services

Each domain is organized into functional groupings aligned to NAICS codes, similar to how services are structured under GSA MAS and other large IDIQ vehicles. This alignment helps agencies efficiently identify qualified contractors for specific mission needs.
