One Acquisition Solution for Integrated Services Plus or OASIS+ is a suite of governmentwide, multiple-award contracts designed to support federal agencies’ procurement requirements for services-based solutions. This suite of services contracts is available for use by agencies throughout the Federal Government who hold a Delegation of Procurement Authority or DPA.

OASIS+ is a collection of indefinite delivery, indefinite quantity or IDIQ contracts, of which the contract base period is five years with one option period of five years that may extend the cumulative contract ordering period to 10 years. Task orders can be awarded under OASIS+ any time prior to the expiration of the ordering period of the master contracts. Notwithstanding, the OASIS+ IDIQ master contracts (contractor specific) can have different award dates; however, all contracts for each specific MAC have the same contract end dates (e.g., all of the Small Business contracts will end on the same date).
