We are having an issue with a contractor it seems they want to refuse the acceptance of a Task Order. I requested a proposal which I believe I don't have to do because everything is already negotiated and I'm just ordering the quantity so I feel like this is a just a formality that I don't have to do go through but I'm not the contracting officer, so i'm doing what I'm told. The contractor was expecting the maximum values and its effecting the bottom line despite the government exceeding the minimum quantity of the Task Order value and the overall IDIQ minimum. They simply undercut themselves so they said they don't want to provide a proposal. I feel the next step is to send them Task Order and see if they refuse to perform. Can they refuse to accept a Task Order under a single award IDIQ? I have never been in this situation before.
