If you are negotiating a deal, expect a lengthy round of bargaining. Don't subjugate your position by setting artificial deadlines. The first proposal is merely the opening bid. Stay positive and suggest alternatives. You must be willing to compromise. "No" is a word rarely used. If you hear, "We have to think about it," "We are not sure" or "There is a small issue" assume that you are being told "No" in a nice way. Mirror these tactics if you need to say, "No." Expect the negotiations to continue even after contracts have been signed.
