Defense Contract Audit Agency (DCAA) provides audit and financial advisory services to the Department of Defense (DOD) and other federal entities responsible for acquisition and contract administration. DCAA’s role in the financial oversight of government contracts is critical to ensure DOD gets the best value for every dollar spent on defense contracting. DCAA operates under the authority, direction, and control of the Under Secretary of Defense (Comptroller)/Chief Financial Officer. Its work benefits our men and women in uniform and the American taxpayer. The Agency’s primary function is to conduct contract audits and related financial advisory services. Contract audits are independent, professional reviews of financial representations made by defense contractors, and DCAA helps determine whether contract costs are allowable, allocable, and reasonable.
