One Acquisition Solution for Integrated Services Plus (OASIS+) is GSA’s next-generation contract to provide government agencies with contractual solutions to complex professional service-based requirements on a global basis.  OASIS+ addresses the government’s growing need for solutions that contain multiple disciplines and includes all components required to formulate a total solution.  Solutions can include ancillary support, may be commercial and/or non-commercial, using a variety of contract types including fixed price, cost reimbursement, time and materials/labor hour, or a hybrid mix of contract types.

OASIS+ is organized by functional groupings of related services referred to as Domains.  For task orders placed under OASIS+, professional services may be broadly defined as those services most closely aligned with the following awarded Domains:
