Sales Fall Out From Commission

I received an email late in the day yesterday detailing a possible commission structure. I was not happy at the proposed commission and had to take a few minutes to digest the information. It took a couple of hours, but I reflected and thought about the potential changes. I wrote down the list of the opportunities, what structure would work for me, and also what would not work.
It is hard to let a potential deal go through if it is not a strong enough commission structure, but I am willing to let it happen if I cannot get what I want and need too. The relationship has to work both ways.
