    FAR 44.301Objective.

    Plain-English Summary

    FAR 44.301 states the purpose of a contractor purchasing system review (CPSR) and explains why the review matters in federal contracting. It covers two core subjects: first, the review’s objective is to evaluate how efficiently and effectively a contractor spends Government funds when it buys supplies or services from subcontractors; second, it assesses whether the contractor complies with Government policy in subcontracting. The section also explains the practical role of the CPSR in the approval process for a contractor’s purchasing system, because the review gives the administrative contracting officer (ACO) the information needed to grant, withhold, or withdraw approval. In practice, this means the CPSR is not just an audit exercise—it is a management tool that affects whether a contractor’s purchasing system is considered acceptable for Government work. Contractors should understand that their subcontracting practices can directly affect system approval status, while contracting officials use the CPSR to protect the Government’s interests and ensure responsible use of public funds.

    Key Rules

    Evaluate spending efficiency

    The CPSR is intended to determine whether the contractor spends Government funds efficiently and effectively when subcontracting. The focus is on whether purchasing practices support good value, sound judgment, and responsible use of taxpayer dollars.

    Check policy compliance

    The review also measures whether the contractor follows applicable Government policy in its subcontracting activities. This includes adherence to required procedures, controls, and standards that govern how subcontract awards are made and managed.

    Support ACO approval decision

    The CPSR provides the ACO with a factual basis for deciding whether to approve, withhold approval of, or withdraw approval from the contractor’s purchasing system. The review is therefore directly tied to system approval status, not merely informational reporting.

    Focus on subcontracting practices

    The section is specifically about purchasing system performance in the subcontracting context. It is not a general review of all contractor operations, but a targeted assessment of how the contractor buys from subcontractors using Government funds.

    Responsibilities

    Administrative Contracting Officer (ACO)

    Use the CPSR results as the basis for deciding whether to grant, withhold, or withdraw approval of the contractor’s purchasing system. The ACO must rely on the review to make an informed approval determination.

    Contractor

    Operate a purchasing system that spends Government funds efficiently and effectively and complies with Government policy when subcontracting. The contractor must maintain practices that can withstand CPSR scrutiny because system approval depends on performance.

    Reviewing officials / CPSR team

    Evaluate the contractor’s purchasing system for efficiency, effectiveness, and policy compliance in subcontracting. Their findings must provide the ACO with a meaningful basis for the approval decision.

    Practical Implications

    1

    A CPSR can affect whether a contractor’s purchasing system remains approved, which can influence contract administration and future award confidence.

    2

    Contractors should expect scrutiny of subcontracting controls, documentation, and decision-making—not just price reasonableness, but overall purchasing discipline.

    3

    Weak purchasing practices can lead to withheld or withdrawn approval, creating administrative risk and potentially increasing oversight on current and future contracts.

    4

    The review is meant to protect Government funds, so contractors should be prepared to show both compliance and business judgment in subcontracting decisions.

    5

    For contracting officers, the CPSR is a key risk-management tool; ignoring poor purchasing system performance can expose the Government to inefficient spending and policy violations.

    Official Regulatory Text

    The objective of a contractor purchasing system review (CPSR) is to evaluate the efficiency and effectiveness with which the contractor spends Government funds and complies with Government policy when subcontracting. The review provides the administrative contracting officer (ACO) a basis for granting, withholding, or withdrawing approval of the contractor’s purchasing system.
