A derogatory term in the sales world, an order taker is someone who has no real sales ability. They're just going through the motions and don't have the skills to actually sell someone something. The order taker relies on existing accounts that will just reorder when they need something, or they rely on inbound calls to make sales. The worst order takers are the ones who think they're big stuff, but are really just chalking up sales that are really driven by price or high demand, and having nothing to do with the ability of the salesperson.
Steve is just an order taker. He couldn't close a tough sale if his life depended on it.
