But, briefly, the transactional model is one in which you require some customer communication in order to close the deal and is typically closed via inside sales reps. Enterprise deals are larger, cost more and typically require on the ground reps and a lot more customer facetime in order to close deals.
That's interesting. In the freight, and oil services industries, transactional is often used to describe spot market arrangements versus contractual ones. I think that makes sense, but I need to think about it a bit more as it relates to rivalrous goods.
