Defense prime contractors with cost-reimbursement or time-and-materials contracts above the simplified acquisition threshold are subject to Contractor Purchasing System Reviews conducted by the Defense Contract Management Agency. A CPSR examines whether the contractor's purchasing system meets 24 criteria defined in DFARS 252.244-7001, including competition adequacy, consent-to-subcontract compliance, and purchasing file documentation. A system found inadequate can result in withheld payments and mandatory corrective action plans. A virtual assistant focused on purchasing system compliance keeps records current and reduces the risk of an adverse CPSR finding.
What CPSR Evaluators Actually Examine
DCMA CPSR teams arrive with a structured evaluation checklist that covers purchase order files, sole-source justifications, competition waivers, consent requests, and subcontractor responsibility determinations. According to DCMA's CPSR guidebook, evaluators typically sample 50 to 100 purchase files per review and assess whether each file contains required elements: solicitation documentation, source selection rationale, price reasonableness determination, and relevant certifications. A virtual assistant builds and maintains a CPSR file checklist template applied to every purchase above the micro-purchase threshold, ensuring that files are complete at the time of purchase rather than reconstructed before an audit.
Consent-to-Subcontract Threshold Management
FAR 44.204 and DFARS 244.403 require prime contractors to obtain contracting officer consent before awarding subcontracts above specified thresholds on cost-reimbursement contracts. Thresholds vary by contract type and subcontract type. A virtual assistant maintains a consent threshold register by contract, tracks subcontract awards approaching the consent threshold, prepares consent request packages including subcontractor cost or pricing data and technical evaluation memoranda, and logs contracting officer responses. Missing a required consent is a direct CPSR deficiency and can trigger withholding of contract payments under DFARS 252.242-7005.
Sole-Source Justification Documentation
Purchasing system adequacy requires that sole-source purchases above the micro-purchase threshold be supported by written justifications establishing that competition was not practicable. Common deficiencies cited in CPSR findings include missing or inadequate sole-source justifications, reliance on convenience rationale rather than legitimate exception, and failure to document follow-on competition plans. A virtual assistant maintains a sole-source justification template library organized by FAR exception type, tracks the dollar value and frequency of sole-source awards by vendor to identify patterns that may draw evaluator scrutiny, and flags sole-source patterns that exceed reasonable thresholds for the contract's purchase volume.
Subcontractor Responsibility Determination Records
DFARS 252.244-7001 requires prime contractors to perform and document responsibility determinations for their subcontractors. These determinations assess financial capability, technical capability, performance history, and integrity. A virtual assistant maintains a subcontractor qualification file for each active subcontractor that includes financial statements, past performance references, SAM.gov registration confirmation, and exclusion check documentation. Refreshing these files annually and before each new award ensures the prime can demonstrate an adequate responsibility determination process to CPSR evaluators.
Corrective Action Plan Tracking After Adverse Findings
When DCMA issues an Approved With Corrective Actions or Disapproved rating, the prime must submit a corrective action plan and implement system improvements within a defined timeframe. DCMA re-evaluates the system after the corrective action period closes. A virtual assistant tracks each corrective action item, assigns internal owners, maintains a completion status dashboard, and prepares the written response package for DCMA review. Firms that move quickly on corrective actions reduce the period of payment withholding and demonstrate the systematic responsiveness that improves DCMA's confidence in the purchasing system.
Proactive Compliance as a Competitive Advantage
Prime contractors with Approved purchasing system ratings face fewer subcontract consent requirements, experience faster invoice approval cycles, and carry lower audit risk on follow-on awards. Maintaining that rating requires daily file hygiene, not just pre-audit scrambling. A virtual assistant provides the consistent attention that keeps the purchasing system in a permanently audit-ready state.
