What a Post-Award Accounting System Audit Reviews
The review typically examines the accounting practices used to record contract costs and determine whether the contractor follows established policies. Auditors may trace transactions from source documents through subsidiary records and the general ledger into contract reports and invoices.
- Direct costs: Labor, materials, subcontract costs, and other contract-specific expenses should be properly identified.
- Indirect costs: Indirect expenses should be accumulated in appropriate pools and allocated consistently.
- Labor accounting: Employee time and labor charges should support the contracts and activities to which costs are assigned.
- Billing: Invoices and claimed costs should reconcile with accounting records and applicable contract provisions.
- Internal controls: Approvals, reconciliations, access rights, and transaction review procedures should operate consistently.
Because the review occurs after contract award, actual operating evidence becomes especially important. Accounting records should demonstrate that documented procedures are reflected in day-to-day transaction processing.
Transaction Processing and Accounting Controls
Post-award reviews often examine how financial transactions move through the accounting system. Invoice capture, extraction, validation, matching, approval, posting, and account assignment should preserve sufficient information to support later review. Accurate gl coding helps ensure that expenses are assigned to the appropriate general-ledger account, project, cost center, or contract.
The accounting system should also maintain appropriate controls over journal entries, adjustments, reconciliations, and period-end closing. Reviewers may examine whether entries are supported by source documentation and whether changes are properly authorized.
Accrual accounting is particularly relevant when contract expenses are incurred before corresponding invoices are received. Finance teams can use AI-native workflows for accruals to support journal preparation, ERP posting, approvals, and audit evidence during the close process.
Supporting records for these activities can include Audit Trails For Accruals, which document steps in accrual preparation, review, approval, and processing and help establish traceability for accounting and compliance purposes.
Procurement, Vendors, and Audit Evidence
Procurement transactions are another important part of a post-award accounting review because purchases can become direct or indirect contract costs. Reviewers may trace requisitions, purchase orders, receipts, invoices, approvals, and payments to determine whether costs are properly authorized and recorded.
Audit Trails For PO can provide records of vendor-payment and approval activity, including actions performed by users or automated workflows during approval and reconciliation. Such evidence can help connect procurement activity with accounting entries.
Vendor communication and transaction status can also affect documentation quality. A Vendor Portal can allow vendors to track invoice and purchase-order status, view transaction history, and communicate with accounting teams through structured workflows.
Vendor controls should also align with broader governance practices. Vendor Award Governance covers the control framework surrounding vendor selection and award decisions and is relevant when evaluating whether procurement decisions are appropriately documented and governed.
Tax, Chart of Accounts, and ERP Integration
Post-award accounting reviews may consider whether tax treatment is accurately reflected in contract-related transactions. Finance teams should validate jurisdiction, nexus, exemptions, and applicable tax rules and maintain appropriate supporting evidence. A properly structured chart of accounts can separate tax categories and improve visibility into tax-related balances and reporting.
Accurate sales tax accounting requires appropriate tax accounts, transaction validation, and documentation supporting the applicable treatment. These controls can help identify incorrect tax amounts and provide evidence when tax transactions are reviewed as part of a broader accounting examination.
ERP configuration is also important because government-contract accounting may depend on consistent integration between procurement, project accounting, general ledger, billing, and reporting modules. When contractors use netsuite, for example, maintaining aligned GL structures and connected finance workflows can support consistent account mapping and reporting during system operations or migration activities.
The Hyperbots Platform can support finance and accounting workflows through agentic AI, including document processing and ERP integration, helping organizations structure transaction information within connected finance processes.
Revenue and Contract-Related Audit Evidence
A post-award accounting review can intersect with specialized accounting audits when contract activity affects revenue recognition or other financial reporting areas. A Revenue Accounting Audit examines revenue-related records, processes, and controls to determine whether accounting treatment is properly supported.
A Revenue Accounting Audit Trail provides a documented history of revenue-related transactions, adjustments, approvals, and other relevant accounting activity. This type of evidence can help reviewers connect reported revenue with the underlying records and control procedures.
Preparing for a Post-Award Accounting System Audit
Preparation should focus on demonstrating that the accounting system operates consistently with documented policies and contract requirements. Finance, accounting, contracts, procurement, and IT teams can jointly review critical workflows and organize supporting evidence before an audit begins.
- Reconcile contract-related subsidiary records with the general ledger.
- Review direct and indirect cost classifications.
- Test labor charging and timekeeping procedures.
- Validate procurement, invoice, billing, and approval controls.
- Review user access and transaction authorization procedures.
- Organize source documents and audit evidence for significant transactions.
- Confirm that financial and contract reports can be traced to accounting records.
Regular reviews of these areas help contractors maintain reliable accounting records throughout contract performance rather than treating audit preparation as a one-time activity.
Summary
Post-Award Accounting System Audit evaluates whether a contractor's accounting system continues to support accurate government contract cost accounting after contract award. The review covers direct and indirect costs, labor, procurement, billing, tax treatment, ERP configuration, internal controls, and audit evidence. Maintaining traceable transactions, consistent cost allocation, appropriate approvals, and reliable financial reporting helps demonstrate that contract costs are properly recorded and supported.
