Defense contractors on cost-reimbursement and other CAS-covered work operate under a payment mechanism most commercial suppliers never encounter: the government can hold back a slice of every progress payment when it decides one of your internal systems falls short. That mechanism runs through DFARS 252.242-7005, the clause that names the six contractor business systems and ties their approval status directly to your cash flow. Understanding how the clause defines, disapproves, and penalizes each system is the difference between a routine audit finding and a ten percent hold on portfolio-wide payments.
Background
The clause groups six internal systems, each governed by its own DFARS clause. Accounting sits under 252.242-7006 and governs how a contractor records and reports costs. Earned Value Management falls under 252.234-7002 and covers integrated cost and schedule performance measurement. Estimating is covered by 252.215-7002 and addresses how proposal costs are built. The Material Management and Accounting System, or MMAS, runs under 252.242-7004 and governs material planning and consumption. Property Management is governed by 252.245-7003 and covers control of government property, and Purchasing by 252.244-7001, which governs subcontract and supplier management. A business system is acceptable when it complies with the terms of its applicable clause, and each clause spells out the specific criteria that define compliance for that system. The Defense Contract Management Agency and the Defense Contract Audit Agency together review these systems, with the contracting officer making the final determination. These clauses reach only CAS-covered contracts where the corresponding system clause is included, so the exposure depends entirely on which clauses your contracts actually carry.
Disapproval turns on a significant deficiency, a shortcoming in the system so significant that it materially affects the ability of officials to rely on information the system produces. A single significant deficiency is enough for a contracting officer to disapprove the system. Disapproval is not a paperwork footnote. It flips a switch that pulls cash out of every affected invoice until the contractor closes the gap, and it stays flipped until the government, not the contractor, confirms the fix.
Key Details
When a contracting officer disapproves a system for one or more significant deficiencies, the officer withholds five percent of amounts due from progress payments and performance-based payments. One disapproved system caps the withholding at five percent. If the officer disapproves more than one system, the withholding rises to ten percent in total. That ten percent is also the aggregate ceiling: total payment withholding under 252.242-7005 cannot exceed ten percent of progress payments across the identified contracts, no matter how many systems are flagged.
The relief valve is the corrective action plan. Once the contractor submits an acceptable corrective action plan, the contracting officer reduces the withholding from five percent to two percent for that system. The plan does not have to prove the deficiency is already fixed; it has to be acceptable as a credible path to correction. That single step recovers three-fifths of the withheld cash, which makes the corrective action plan the fastest lever a contractor controls.
Correction itself starts a clock. Within 90 days of receiving the contractor's written notification that it has corrected the significant deficiencies, the contracting officer must act. If the officer verifies the correction, the withholding is discontinued and previously withheld amounts are released. If the officer determines the deficiencies are not yet corrected, the withholding continues, backed by a documented rationale. And if the officer lets the 90 days pass without making that determination, the regulation does not simply freeze the hold in place: the withholding directly related to the deficiencies is reduced by at least 50 percent automatically. Verification runs through the Defense Contract Audit Agency or the relevant functional specialist, who tests whether the deficiencies are genuinely closed. Inaction, in other words, cuts in the contractor's favor rather than the government's.
Subpart 242.70 sets the procedural frame around the clause. It directs the contracting officer to coordinate with the auditor or functional specialist before disapproving a system, to document the significant deficiencies, and to give the contractor an opportunity to respond in writing before the disapproval and withholding take effect. The withholding is applied per contract that contains the relevant system clause, but the aggregate across those contracts is what the ten percent ceiling measures. Once withholding begins, it continues until the deficiency is corrected and verified, so the elapsed time between disapproval and an acceptable corrective action plan is money the contractor does not see. That structure rewards contractors who maintain adequate systems continuously rather than scrambling after a finding, because the reduction to two percent and the eventual release both depend on documentation the contractor should already hold.
What It Means for Contractors
For a contractor, the business-system regime is a cash-flow control as much as a compliance one. A ten percent hold on progress payments across a portfolio of active contracts can starve working capital faster than a single disputed cost. Treat the six systems as revenue infrastructure, not back-office housekeeping. The first practical move is to know which clauses your contracts carry, because a system you never certified against a clause cannot be disapproved under it, and a clause you did accept is live exposure. The second move is speed on the corrective action plan. Because an acceptable plan drops the withholding from five to two percent before any fix is verified, drafting that plan is the highest-return response to a disapproval letter, and it should be ready in outline before an audit ever lands. The third move is managing the 90-day clock deliberately: send the correction notification in writing, date it, and track it, because that notice is what forces the contracting officer to verify and release rather than leave the hold in place. Keep the DCAA or functional-specialist reviewer supplied with the evidence they need to close the finding, since their verification is the gate between a two percent hold and full release. Contractors carrying several disapproved systems should sequence corrections toward the aggregate ten percent ceiling, fixing the systems that unlock the most withheld cash first. None of these clauses apply on a contract that does not include them, so the single most valuable audit a contractor can run is on its own contract files, mapping which of the six clauses appears where before a contracting officer maps it first.
