“The script we came up with hit all the best practices of negotiation we’ve talked about so far. Here it is by steps: A “No”-oriented email question to reinitiate contact: “Have you given up on settling this amicably?” A statement that leaves only the answer of “That’s right” to form a dynamic of agreement: “It seems that you feel my bill is not justified.” Calibrated questions about the problem to get him to reveal his thinking: “How does this bill violate our agreement?” More “No”-oriented questions to remove unspoken barriers: “Are you saying I misled you?” “Are you saying I didn’t do as you asked?” “Are you saying I reneged on our agreement?” or “Are you saying I failed you?” Labeling and mirroring the essence of his answers if they are not acceptable so he has to consider them again: “It seems like you feel my work was subpar.” Or “… my work was subpar?” A calibrated question in reply to any offer other than full payment, in order to get him to offer a solution: “How am I supposed to accept that?” If none of this gets an offer of full payment, a label that flatters his sense of control and power: “It seems like you are the type of person who prides himself on the way he does business—rightfully so—and has a knack for not only expanding the pie but making the ship run more efficiently.” A long pause and then one more “No”-oriented question: “Do you want to be known as someone who doesn’t fulfill agreements?”
