Contracting officer

A contracting officer is the person with authority to bind the buying organization: signing the contract, issuing amendments, and administering delivery. During a live competition the role tightens further — the contracting officer (sometimes titled procurement officer, sometimes a distinct authority) is typically the sole official channel for bidder communications, a rule that exists to keep the process fair and the record clean.

The single-channel rule is the one suppliers break at their peril. Contacting the program directly during a competition — to lobby, to clarify, to share a draft — is the classic disqualifier, because it creates the appearance of unequal access that challenge processes exist to punish. Everything goes through the officer, in writing, by the deadline. After award, the officer administers changes: if a conversation with the program moves the scope, it is real when the officer's amendment says it is. Free research feeds such as pubsec.pro help you identify which organization and office runs a category before first contact, so the first contact lands on the right desk.
