One Acquisition Solution for Integrated Services (OASIS) | GSA


OASIS is a government-wide acquisition contract administered by the General Services Administration. The OASIS contract is designed to provide agencies with one solution to procure integrated professional services including: management consulting, program management, financial management, engineering, and scientific services.

Recognizing the need for agencies to procure non-IT services through a convenient contract vehicle, GSA created OASIS. While agencies can procure professional services through GSA’s Multiple Award Schedules Program, OASIS differs in that it consists of standardized labor categories and allows for all contract types at the task-order level, including cost-reimbursement and cost plus contracts.
