Contracting Officer(CO)

The government official with the authority to enter into, administer, and terminate contracts on behalf of the U.S. government.

Overview

The Contracting Officer (CO) is the only person in the government with the legal authority to obligate federal funds through contracts. They sign awards, approve modifications, issue task orders, and can terminate contracts. No commitment from any other government employee is binding unless the CO authorizes it.

Why It Matters in GovCon

Understanding the CO's role is essential for every contractor. If someone other than the CO directs you to perform additional work or change scope, you have no contractual obligation — and no guarantee of payment. Always get direction in writing from the CO.

Key Details

  • Authority: COs hold a warrant that specifies the dollar limits of their contracting authority.
  • Types: Procuring Contracting Officers (PCOs) award new contracts; Administrative Contracting Officers (ACOs) manage them post-award; Termination Contracting Officers (TCOs) handle contract closures.
  • Delegation: COs may designate a Contracting Officer's Representative (COR) to handle day-to-day technical oversight, but the COR cannot authorize changes or obligate funds.
  • Communications: All formal contract communications should go through or be acknowledged by the CO.
