Adequate Accounting System (AAS)

An accounting system that can properly track, separate, allocate, and report costs on government contracts. Especially important for contractors performing cost-reimbursement, time-and-materials, labor-hour, incentive-type contracts, or contracts involving progress payments.

What Is an Adequate Accounting System?

In government contracting, an adequate accounting system is more than standard bookkeeping. It is a system of records, controls, policies, and procedures that helps a contractor accurately capture contract costs, support billing, and comply with federal cost requirements.

For many contractors, especially those pursuing cost-based federal work, an adequate accounting system is a key part of pre-award readiness and ongoing compliance.

Key Characteristics

Separates direct and indirect costs

Tracks costs by contract or cost objective

Identifies and excludes unallowable costs

Supports reliable job-cost reporting

Includes documented internal controls and accounting procedures

How It Works in Government Contracting

An adequate accounting system often becomes relevant before contract award, especially when a contractor is pursuing cost-reimbursement or other higher-risk contract types. The government may review the system to confirm that the contractor can properly accumulate, manage, and report costs.

It is used by contractors, contracting officers, administrative contracting officers, and auditors. The system helps ensure that labor, materials, overhead, and other expenses are charged correctly and supported by records.

In practice, it allows the contractor to assign costs to the right contract, maintain compliant billing practices, and support audits or financial reviews throughout performance.

Regulatory Framework

Adequate accounting systems are closely tied to federal cost and compliance requirements. Relevant guidance may come from FAR Part 31, DFARS business system rules, and agency-specific audit or pre-award review criteria.

For DoD contractors, accounting system adequacy is often reviewed as part of contractor business system oversight.

Why It Matters for Contractors

A strong accounting system can directly affect contract eligibility, audit readiness, and payment reliability. Without an adequate system, a contractor may face delays in award, compliance findings, billing issues, or increased government scrutiny.

It also has strategic value. A compliant system supports accurate pricing, defensible indirect rates, stronger internal controls, and more efficient contract administration.

Common Misconceptions About Adequate Accounting Systems

An adequate accounting system is only needed after award.

It is often reviewed before award, especially for cost-based contracts.

Basic accounting software automatically makes a system adequate.

Software alone is not enough. The system must support government-specific cost tracking, allowability controls, and contract-level reporting.

Only large contractors need an adequate accounting system.

Small businesses may also need one if they pursue certain federal contract types.
