​Winning a government contract isn’t just about submitting a strong bid—it’s about understanding who’s making the decisions. In the world of federal procurement, Contracting Officers (COs) hold the keys to government spending. Whether you're bidding on a small contract or a multi-million-dollar award, the CO determines whether your company gets the deal.

This article will break down the role of a Contracting Officer, how they impact federal contracting, and what businesses can do to work effectively with them.

What is a Contracting Officer (CO)?

A Contracting Officer (CO) is a federal official authorized to enter into, manage, and terminate contracts on behalf of the U.S. government. They ensure that government purchases comply with the Federal Acquisition Regulation (FAR) and that taxpayer dollars are spent responsibly.

COs are responsible for:

• Soliciting and awarding contracts
• Evaluating contractor proposals and performance
• Managing contract modifications and disputes
• Ensuring legal and regulatory compliance

The government entrusts COs with significant authority, and businesses must build strong relationships with them to succeed in federal contracting.

The Contracting Officer’s Authority

Not all COs have the same level of power. The government issues warrants that define the maximum dollar value a CO can authorize. These vary based on experience, agency, and contract type.

There are three primary levels of Contracting Officers:

1. Administrative Contracting Officers (ACO) – Manage existing contracts, ensuring compliance and handling modifications.
2. Procuring Contracting Officers (PCO) – Award contracts and oversee the solicitation and selection process.
3. Termination Contracting Officers (TCO) – Handle contract terminations when performance issues arise or funding is cut.

Each CO has specific responsibilities, but all share the goal of securing the best value for the government while ensuring contractors meet their obligations.

How Businesses Can Work Effectively with COs

Understanding how to interact with Contracting Officers can make or break your success in federal contracting. Here’s how you can improve your chances:

1. Do Your Homework – Study past contract awards, the agency’s procurement history, and any specific needs outlined in SAM or the Advanced Procurement Portal (APP).
2. Submit a Strong Proposal – A well-written, compliant proposal makes the CO’s job easier. Follow all instructions and avoid cutting corners.
3. Maintain Compliance – COs prioritize vendors that understand FAR requirements. Ensure your business remains in good standing.
4. Communicate Professionally – Build rapport with COs by responding promptly to inquiries and demonstrating your ability to deliver.
5. Leverage Your Set-Asides – If you're a small business, SDVOSB, HUBZone, or 8(a) firm, emphasize your set-aside eligibility. Many COs must meet small business procurement goals.

Bonus: CO vs. KO—What’s the Difference?

You might hear KO instead of CO in federal contracting, especially in the Department of Defense (DoD). The difference? Nothing—except the letters.

The "K" in KO comes from the federal government’s contract numbering system, where the letter "K" is used to designate a contract. Since "CO" is widely recognized as "Commanding Officer" in military settings, DoD and other agencies use KO (for "Contracting Officer") to avoid confusion.

So, whether you see CO or KO, it refers to the same role—just different terminology based on the agency.

The Bottom Line

A Contracting Officer (CO/KO) can be the deciding factor in your federal contracting success. Understanding their role, building strong relationships, and ensuring compliance with FAR regulations will position your business for long-term success.
