Contracts and task orders from USASpending.gov (FPDS) whose period of performance ends within 18 months, valued at $25K or more, excluding IDIQ ceilings and government-owned, contractor-operated facility contracts. Co-terminous orders from the same vendor, agency, NAICS and PSC ending in the same month are grouped. The solicitation date is an estimate (about six months before the contract ends): FedSift does not know whether a follow-on has been posted, so check SAM.gov.
