CPSR stands for Contractor Purchasing System Review, a formal evaluation conducted by the Defense Contract Management Agency (DCMA) to assess how effectively a federal contractor spends government funds when hiring subcontractors and purchasing materials. If your company holds government contracts and your annual government sales exceed $50 million, a CPSR is likely in your future.
What a CPSR Evaluates
The core purpose of a CPSR is straightforward: the government wants to know that when you subcontract work or buy supplies using taxpayer dollars, you’re doing it efficiently, competitively, and in compliance with federal acquisition rules. The review looks at your internal purchasing system as a whole, not just individual transactions. Reviewers examine whether your company has written procurement policies, whether your staff follows them consistently, and whether the prices you pay subcontractors are fair and reasonable.
The legal foundation for CPSR comes from the Federal Acquisition Regulation (FAR) Subpart 44.3. Under that regulation, the administrative contracting officer (ACO) assigned to your contracts decides whether a CPSR is needed and ultimately grants, withholds, or withdraws approval of your purchasing system based on the review’s findings.
Who Needs a CPSR
A CPSR is triggered when a contractor’s sales to the government are expected to exceed $50 million during a 12-month period. Not every dollar of government work counts toward that threshold, though. Competitively awarded firm-fixed-price contracts, fixed-price contracts with economic price adjustment, and commercial item sales under FAR Part 12 are excluded from the calculation. The $50 million figure applies to the remaining contract types, which are typically cost-reimbursement, time-and-materials, or sole-source contracts where the government bears more pricing risk.
Beyond hitting the dollar threshold, your company must also hold at least one prime contract containing FAR Clause 52.244-2. That clause specifically reserves the government’s right to review your purchasing system. Even if you’re below $50 million, the contracting officer can still direct a CPSR at their discretion if circumstances warrant it.
How the Review Works
DCMA conducts the review, typically at your facility. The process starts well before auditors arrive. Your company will receive advance notice and a request for documentation, including your written purchasing policies and procedures manual, a list of recent subcontracts and purchase orders, and supporting files for those transactions.
During the on-site review, DCMA analysts pull a sample of your subcontract files and examine them in detail. They’re checking whether you obtained adequate competition among potential subcontractors, performed cost or price analysis before awarding subcontracts, negotiated fair and reasonable prices, included required contract flowdown clauses (federal requirements that must be passed along to your subcontractors), and documented the rationale for your decisions at each step.
The review also looks at your organizational structure: whether purchasing authority is clearly defined, whether there’s appropriate separation of duties, and whether management oversight exists to catch errors or policy violations before they become patterns.
What Your Purchasing System Needs
The foundation of a successful CPSR is a comprehensive written procurement procedures manual. This document should cover your company’s approach to competition, sole-source justification, cost and price analysis, supplier selection, and consent-to-subcontract requirements. DCMA reviewers will compare what your manual says against what your actual subcontract files show. A gap between policy and practice is one of the fastest ways to receive findings.
Your subcontract files themselves need to tell a complete story. Each file should contain the purchase request, evidence of competition (or a written justification for limiting competition), a cost or price analysis, negotiation documentation, the executed subcontract or purchase order, and any required government consent. Missing documentation in even a handful of files can result in deficiency findings that put your system approval at risk.
Training matters too. The reviewers want to see that your procurement staff understands federal requirements, not just your internal procedures. Maintaining records of regular training on FAR compliance, cost accounting standards, and ethics requirements demonstrates that your company takes the purchasing function seriously.
Approved vs. Disapproved Systems
At the end of the review, the ACO will issue one of two determinations: your purchasing system is approved, or it is disapproved. An approved system means you can continue operating with the normal level of government oversight on your subcontracting activity. For many contract types, an approved system also means you won’t need advance government consent for individual subcontracts below certain dollar thresholds, which significantly speeds up your operations.
A disapproved system creates real problems. When your purchasing system lacks approval, the government can increase oversight of every subcontract you issue, requiring advance consent on transactions that would otherwise be routine. This slows your procurement cycle and increases your administrative costs. A disapproved system can also factor into source selection decisions on future contract competitions, since evaluators may view your company as a higher risk. In some cases, the government may withhold a percentage of payments on cost-type contracts until deficiencies are corrected.
If your system is disapproved, you’ll receive a corrective action plan outlining the specific deficiencies. You’ll have an opportunity to address those findings and request a follow-up review. The goal is to bring your system back into compliance as quickly as possible to restore normal operations and payment terms.
How Often Reviews Occur
Once your purchasing system is approved, it doesn’t stay approved indefinitely without further scrutiny. DCMA typically conducts follow-up reviews on a recurring cycle to ensure continued compliance. If your system was approved without significant findings, the interval between reviews may be longer. If the prior review surfaced concerns or if your subcontracting volume has grown substantially, you may see reviewers again sooner. The ACO retains discretion to schedule a review at any point if new information suggests your system may have drifted out of compliance.
Between formal reviews, maintaining your purchasing system is an ongoing responsibility. Companies that treat CPSR preparation as a last-minute scramble tend to struggle. Those that build compliant habits into their daily procurement operations, with consistent file documentation, regular internal audits, and up-to-date procedure manuals, find that the formal review confirms what they already know about their own systems.
