A small business subcontractor working for a prime contractor has not received final payment for work completed from April 2012 to August 2012 due to the non-acceptance of a major deliverable (a report) by the government. The prime contractor has a cost plus fixed fee contract with the federal government. There have been several iterations of the deliverable in question primarily due to the government COTR changing three times. The first COTR asked for more detail and when revised, a new COTR was appointed, and asked for less detail. The deliverable was revised again to meet his request, and by then, a new COTR was appointed, and again asked for more detail. The prime contractor is in standby mode and not questioning the irregularity in the inspection of the deliverable. The small business subcontractor would like to know what rights, if any, it has in such a situation to elevate this irregular review of the deliverable in order to obtain acceptance and receive payment.
