It covers management consulting, IT services, R&D, engineering, logistics, financial management, and more. Any federal civilian agency or DoD component can issue task orders through OASIS+, making it the most broadly accessible professional services vehicle in the federal government.

    OASIS+ Market Context

    Why OASIS+ matters in the federal contracting landscape and its role in agency acquisition strategy.

    OASIS+ is the dominant civilian-agency vehicle for complex professional services, succeeding legacy OASIS contracts that collectively drove over $40B in obligations. As a Best-in-Class (BIC) vehicle, OMB actively steers agencies toward OASIS+ for professional services — meaning ordering volume will grow significantly as legacy task orders expire and agencies migrate. The vehicle's unusually broad scope, spanning management consulting, R&D, logistics, and IT services, makes it attractive for firms seeking a government-wide addressable market through a single contract vehicle.

    How OASIS+ Task Orders Work

    Step-by-step: how agencies issue task orders through OASIS+ and what contract holders need to do to compete.

    1. 1Agency confirms the requirement falls within an OASIS+ task area (TA1–TA7) and determines the appropriate pool (Unrestricted or Small Business).
    2. 2Agency selects any socioeconomic set-aside sub-pool if applicable (8(a), HUBZone, SDVOSB, or WOSB).
    3. 3Agency prepares a Request for Task Executive Order Proposals (RTEOP) or RFP and posts it to GSA eBuy, notifying all eligible holders in the selected pool.
    4. 4OASIS+ holders review the RTEOP, submit questions during the Q&A period, and develop full proposals covering technical approach, management plan, past performance, and price.
    5. 5Agency evaluates proposals using best-value or LPTA criteria and awards a task order to the winning offeror.
    6. 6Awarded task order is executed under the holder's OASIS+ base contract, tracked against the vehicle's total ceiling.

    Strategies for Winning OASIS+ Task Orders

    Practical tactics for maximizing your success as a OASIS+ contract holder.

    • 1Map every capability to a specific OASIS+ task area before your next proposal — task area misalignment is the most common deficiency in OASIS+ task order responses.
    • 2Agencies with OASIS+ ordering patterns inherited from legacy OASIS are prime re-compete targets — search USASpending for prior OASIS/OASIS SB awards by agency.
    • 3SB sub-pool set-asides are extremely common — if you hold a socioeconomic certification, lead with it when marketing OASIS+ capabilities.
    • 4Build relationships with GSA contracting officers who manage OASIS+ task orders for the agencies you target — many task orders are drafted with incumbent knowledge.
    • 5OASIS+ and GSA MAS Professional Services cover some of the same territory — position OASIS+ for large, complex multi-year programs and use MAS for simpler, shorter engagements.
    • 6Past performance volume (not just size) matters on OASIS+ — build a portfolio of completed OASIS+ task orders quickly to strengthen future task order bids.
