The Difference Between Commercial and Government Contract Accounting

While accounting fundamentals remain the same across industries, there’s a significant difference between commercial and government contract accounting. For businesses entering the federal marketplace, understanding these differences is critical to staying compliant and competitive.

In commercial accounting, companies enjoy more flexibility. They can choose how to allocate costs, structure internal reporting, and manage pricing. Profit margins, internal policies, and customer agreements largely drive decision-making.

In contrast, government contract accounting is governed by strict regulations—most notably FAR (Federal Acquisition Regulation) and oversight agencies like the DCAA. Key differences include:

• Cost Allowability: Government contracts restrict certain expenses (like entertainment or lobbying), which must be excluded from billing.
• Indirect Rate Structures: GovCon accounting requires calculated and documented indirect rates for overhead and G&A costs.
• Timekeeping Requirements: Contractors must maintain compliant, auditable timekeeping systems—often reviewed by auditors.
• Accounting System Compliance: Systems must meet standards for tracking direct/indirect/unallowable costs and be ready for audit.
• Audit Oversight: Commercial entities rarely face external audits, but government contractors may be audited before, during, and after contract performance.
