Contract Vehicles

ISN’s contract vehicles provide streamlined, flexible, and efficient procurement pathways for current and prospective clients. Our portfolio includes both Government-wide Acquisition Contracts (GWACs) and agency-specific Indefinite Delivery/Indefinite Quantity (IDIQ) contracts that enable federal agencies to access a broad range of mission-critical services.

These contracts support the acquisition of professional solutions across various sectors such as information technology, program management, engineering, logistics, and financial consulting. ISN holds several major contracting vehicles, including OASIS+, GSA Multiple Award Schedule (MAS), and SeaPort NxG, each offering agencies scalable and compliant service delivery.

With a consistent record of performance, proven compliance, and expertise in navigating the complexities of federal procurement, ISN is a reliable partner to government clients nationwide. Our contract portfolio is structured to support both immediate project needs and long-term mission objectives through easy-to-use acquisition methods.

1. OASIS+

OASIS+ (One Acquisition Solution for Integrated Services Plus) is the largest governmentwide, multi-agency IDIQ contract program designed to meet federal agencies’ complex professional service’s needs. Managed by the General Services Administration (GSA), OASIS+ supports a range of service domains including program management, logistics, engineering, financial services, and consulting.

OASIS+ is available for use by all federal agencies, including the Department of Defense and Federally Funded Research and Development Centers (FFRDCs). However, it is not currently open to state or local governments. Orders issued under OASIS+ are considered Interagency Acquisitions under GSA’s statutory authority (40 U.S.C. 501).
