What a Post-Implementation DCAA Review Covers
The review should cover the financial and operational areas affected by the implementation. Rather than focusing only on technical configuration, the reviewer evaluates whether transactions flowing through the system produce appropriate accounting records and supporting evidence.
- Cost accounting: Review direct and indirect cost treatment, account mappings, pools, bases, and allocation structures.
- Labor charging: Examine timekeeping rules, employee assignments, approvals, corrections, and labor distribution.
- Billing: Validate billing classifications, contract information, rate application, and supporting documentation.
- System controls: Review access roles, approvals, change controls, interfaces, and transaction traceability.
- Audit evidence: Confirm that transactions can be traced from source documentation through processing and financial reporting.
ERP Implementation and DCAA Review
For contractors implementing an ERP, the post-implementation review should verify that the configured environment continues to support government-contracting accounting requirements after production deployment. DCAA-Compliant ERP: 2026 Buyer's Guide + AI Audit Tips provides related guidance on ERP capabilities, compliance considerations, and audit-readiness practices.
The review can also validate whether the selected ERP structure supports contract accounting, project costing, indirect rate management, timekeeping, billing, and financial reporting. ERP for Government Contractors: The Complete Guide (2026) provides broader context for evaluating ERP capabilities relevant to government contractors.
Implementation documentation is another important reference point. Teams can compare actual production workflows against the planned lifecycle described in the ERP Implementation Guide for 2025, identifying configuration decisions that should be documented or incorporated into operating procedures.
For cloud environments, the review should also consider interfaces, data flows, user access, configuration governance, and connected finance applications. The Cloud ERP Implementation: Step-by-Step Guide & Best Practice provides context for implementation activities that can later become part of post-production validation.
Testing Transactions and Controls
A practical post-implementation review uses representative transactions rather than relying solely on configuration screens. Reviewers can select transactions from payroll, purchasing, accounts payable, expense reporting, project accounting, billing, and the general ledger and trace them through the complete workflow.
For each sample, the reviewer can compare the source transaction, approvals, system coding, cost classification, posting, downstream reporting, and supporting documentation. This approach helps establish whether the implemented controls function consistently under normal operating conditions.
Organizations using AI-enabled finance workflows can also review how configured Pre Trained Models process structured invoice information and how resulting transactions connect with the contractor's established accounting and approval controls.
Audit Evidence and Documentation
Documentation is a core component of a DCAA-oriented post-implementation review. The organization should maintain evidence showing how system configurations, accounting policies, approval procedures, and transaction processing work together.
Audit Trails can provide a chronological record of actions associated with financial or vendor-management workflows. Reviewing these records helps establish who performed an action, what changed, when the activity occurred, and how the transaction progressed through the process.
The reviewer should compare system evidence with written policies and procedures. Where the production workflow differs from the original implementation design, the organization should update relevant documentation so that operating procedures accurately describe the current environment.
Post-Implementation Review and Close Activities
A Post Implementation Review examines whether an implemented system or project achieved its intended operational objectives and whether lessons from deployment should inform ongoing processes. A DCAA-focused review adds particular attention to accounting controls, contract costs, labor charging, and audit evidence.
The timing of the review can also connect with financial close activities. A Post Close Review examines completed financial close activity and can help identify recurring reconciliation, adjustment, or documentation patterns that should be addressed in subsequent reporting periods.
Compliance Review and Improvement
An Implementation Compliance Review focuses on whether the implemented environment aligns with applicable compliance requirements, documented policies, and established control objectives. For government contractors, this can include reviewing cost classification, labor distribution, indirect cost allocation, billing support, and records maintained for audit purposes.
Findings should be categorized by process, system configuration, control ownership, documentation, and training requirements. Each item can then receive an assigned owner, corrective action, supporting evidence, and a target completion date. This creates a repeatable framework for maintaining the system after implementation rather than treating compliance as a one-time implementation activity.
Best Practices for Post-Implementation DCAA Review
A strong review combines system evidence with actual transaction testing and documented accounting procedures. Contractors should establish a recurring review cycle appropriate to the scope and significance of their system changes.
- Use representative samples: Test transactions across contracts, departments, cost types, and financial workflows.
- Reconcile outputs: Compare system-generated results with approved financial records and supporting schedules.
- Document configuration: Maintain current records of key accounting, labor, billing, access, and workflow settings.
- Review changes: Trace significant configuration or process changes to their approvals and supporting documentation.
- Track remediation: Assign owners and evidence requirements for each identified improvement area.
Summary
Post-Implementation DCAA Review evaluates whether a newly implemented finance or ERP environment continues to support government-contracting accounting and control requirements in live operations. By examining transaction processing, labor charging, cost allocation, billing, system controls, documentation, and audit evidence, contractors can maintain a consistent connection between system configuration and their ongoing financial compliance processes.
