What is an Authorized Negotiator?

An Authorized Negotiator is a person authorized to negotiate with the Government in connection with an offer or modification request. Authorized negotiators can legally bind the company to any changes or updates to the contract. This person is usually assigned during the offer process and transitions to the contract. If this person changes, a contract modification must be done to add a new Authorized Negotiator.
