DCAA Audit Preparation for Government Contractors

A DCAA audit is a review performed by the Defense Contract Audit Agency of a contractor’s financial practices, cost data, systems, or submissions supporting U.S. government contracts. Depending on the engagement, auditors may examine labor charging, indirect-cost allocations, incurred costs, estimating practices, accounting policies, supporting documentation, and compliance with applicable FAR and CAS requirements. The purpose is to assess whether claimed or proposed costs are allowable, allocable, reasonable, and adequately supported.

DCAA primarily provides audit and financial-advisory services for government contract matters, focusing on contractor cost representations, accounting systems, and related financial information. DCMA, the Defense Contract Management Agency, administers contracts and oversees areas such as performance, quality, delivery, property, and contractor business systems. The agencies may both interact with a contractor, but DCAA’s core role is audit while DCMA’s is contract administration and oversight.

Begin by identifying the audit type and assembling the policies, records, system reports, and reconciliations tied to the auditor’s request. Validate that labor, direct costs, indirect pools, allocation bases, and supporting documentation agree across systems. Assign clear owners for each request, retain a request log, and review explanations before submission. Preparation should also include training staff to explain established practices consistently and provide evidence promptly.

Requested records vary by audit, but often include accounting policies and procedures, general-ledger detail, job-cost reports, timesheets, payroll records, indirect-rate calculations, invoices, purchase documentation, reconciliations, cost-allocation support, and prior submissions. Auditors may also request evidence showing how controls operate in practice. Maintaining controlled versions, clear approval history, and traceable links between source records and submissions makes responses easier to support.

No. Cost Accounting Standards applicability depends on the award, contract type, dollar value, business-unit circumstances, and available exemptions. Some contracts may be fully CAS-covered, modified CAS-covered, or exempt. Contractors should evaluate the specific award and maintain a documented basis for that determination. When CAS applies, consistently applying disclosed or established cost-accounting practices is essential to defending allocations and preventing avoidable compliance issues.

FAR Part 31 establishes cost principles used to determine the allowability of costs under government contracts. It addresses topics including reasonableness, allocability, accounting consistency, and specific categories of allowable or unallowable costs. Contractors need reliable policies, account treatment, and supporting records so costs charged directly or indirectly can be evaluated against these principles. It is especially important when preparing incurred-cost submissions and responding to audit questions.

The timeline depends on the audit scope, system maturity, record accessibility, and number of issues identified during an internal review. QMS Learning states that teams can become audit-ready within 30 days of rollout for its training model. In practice, allow additional time to reconcile data, remediate gaps, document procedures, and gather historical support. Starting before an audit notice creates more time for thoughtful correction and evidence validation.

Yes. QMS Learning delivers self-paced, role-specific training supported by an AI Workbench, Manager Dashboard, and Audit-Evidence Package export. The Government Contract Accounting & CAS Compliance Pathway is currently enrolling a pilot cohort and covers CAS, FAR Part 31, DCAA audit preparation, incurred cost submissions, and indirect rates. Team licensing and a 30-minute demo are available for organizations evaluating the pathway.
