What a DCAA Audit Preparation Checklist Covers
A useful checklist should cover the records and processes most relevant to government contracting. This includes the accounting system, indirect cost allocation, labor charging, purchasing, payroll, billing, contracts, and supporting documentation. Each checklist item should identify the responsible owner, required evidence, review status, and location of the supporting record.
- Accounting records: General ledger activity, reconciliations, journal entries, trial balances, and supporting schedules.
- Labor records: Timekeeping data, labor classifications, payroll records, approvals, and labor-cost allocations.
- Contract records: Contract terms, modifications, funding information, billing support, and relevant cost documentation.
- Purchasing records: Purchase orders, invoices, approvals, receipts, vendor records, and payment evidence.
- Indirect costs: Allocation methodologies, cost pools, allocation bases, and supporting calculations.
Invoice, Purchasing, and Accrual Evidence
Invoice and purchasing evidence should demonstrate that recorded costs are supported, properly approved, and traceable to the underlying transaction. The Audit Trails associated with invoice processing can help show actions, timestamps, approvals, and changes throughout the transaction lifecycle.
Purchase-related evidence should also connect requisitions, purchase orders, invoices, receipts, approvals, and payments. Audit Trails For PO can support this review by providing traceability across vendor payment and approval activities.
Accrued costs require particular attention because the checklist should connect the recorded accrual to its underlying obligation and subsequent documentation. Finance teams that manage accruals can review journal entries, supporting schedules, reversals, and related source documents as part of close and audit preparation. Audit Trails For Accruals can further document the steps, approvals, and changes associated with accrual processing.
Labor and Timekeeping Review
Labor documentation should allow costs charged to government contracts to be traced from employee time records through payroll and accounting. Reviewers should verify that timekeeping procedures, approvals, labor classifications, indirect labor allocations, and corrections are consistently supported.
For a focused explanation of the requirements and practical controls involved, DCAA Timekeeping & Labor Cost Tracking Guide explains DCAA timekeeping requirements, labor cost tracking practices, compliance considerations, and ways contractors can maintain audit readiness.
Tax and Financial Control Evidence
Tax-related records should be organized alongside the financial evidence they support. A separate Tax Audit Preparation process can help finance teams review tax filings, transaction classifications, supporting documentation, reconciliations, and relevant payment records within the broader audit-readiness workflow.
Where sales tax verification is part of the review, Audit Trails for Sales Tax Verification can provide a record of verification actions, journal-entry activity, and workflow history. This makes it easier to connect tax review procedures with the accounting records included in the audit package.
Using ERP Systems for Audit Readiness
An ERP should make it practical to retrieve transaction-level evidence while preserving the relationship between source documents, accounting entries, approvals, and reporting. Finance teams evaluating ERP capabilities can use DCAA-Compliant ERP: 2026 Buyer’s Guide + AI Audit Tips to understand ERP selection, integration, migration, and finance workflows that support year-round audit readiness.
For broader technology planning, Cloud ERP System Evaluation Checklist: Guide for 2026 provides criteria for evaluating cloud ERP capabilities, integration, migration considerations, and finance workflow requirements. A well-structured ERP environment can centralize evidence and make checklist completion more consistent across accounting processes.
Final Review and Retrieval Process
Before an audit begins, the finance team should review each checklist item for completeness, consistency, and traceability. Missing documents should be identified by transaction or control area rather than discovered only when an auditor requests them.
Invoice evidence deserves a dedicated retrieval review. Invoice Audit Preparation: Cut Audit Time & Retrieval explains how finance teams can prepare invoice evidence, retrieve invoices efficiently, and build a complete audit-ready trail using structured workflows.
The final checklist should confirm that requested records are accessible, supporting schedules reconcile to the general ledger, approvals are documented, and responsible employees know where evidence is maintained. It should also distinguish completed reviews from items that require follow-up so the audit team has a clear status view.
Summary
A DCAA Audit Preparation Checklist brings accounting, labor, contract, purchasing, tax, and control documentation into one organized readiness process. By linking transactions to approvals, source records, reconciliations, and audit trails, it helps contractors prepare evidence systematically and support reliable financial reporting. A well-maintained checklist also creates a repeatable process that can be updated as contracts, systems, accounting procedures, and audit requirements change.
