How can you get what you want?

Know your margin. Know how far you are willing to go and write it down in advance. Know what you want. Find out in advance what you want to get out of the negotiation and what you want to achieve. Think about your end goal. There is no point in negotiating without knowing what for. Strive for win-win. Think of an outcome in which all parties derive enough benefit from the agreement. Be flexible. Show that you are willing to give up things to acquire others. Use body language. Understand the unspoken. Listen to what is said and what is not. Be informed. Make sure you are aware of as much as possible data related to the subject, but also to the counterparty. What kind of position are they in. How badly do they want the deal. What are the hidden interests. Don't just make concessions. Negotiate each gesture that you are willing to make. Think of variables. Part of the negotiating space can be found in the conditions. A discount, delivery, staggered payment, a fuel card, a laptop, days off. Exchange. Give something and get something in return of equal value or, better yet, of greater value. Come up with a strategy.
