The GSA One Acquisition Solution for Integrated Services (OASIS)+, Indefinite Delivery/Indefinite Quantity (IDIQ) Contracts, were created to provide a fast, cost-effective way for federal agencies to obtain professional services for complex problems with maximum flexibility. GSA has already done the heavy lifting of negotiating and awarding a master government-wide IDIQ program, allowing agency acquisition professionals to expedite the procurement process and focus on mission-critical requirements. You can be assured that your procurements, under the OASIS+ contracts, will meet the best value criteria for Government acquisitions, complying fully with all applicable regulations, with minimal contract access fees.
