Always prepare back up information: If you enter into a negotiation based only on what you believe, you’ve already lost. However, if you have sufficient back up information such as statistics, data or articles you’ve read, your chances of winning the negotiation will increase.
Take a walk: If your negotiation seems to be going nowhere and you both feel stuck or restricted, research shows that moving your body or a change of scenery actually help to reduce your stress level. Walking around the meeting room might not be possible, but try inviting the decision makers outside for some fresh air or coffee. You might be successful in your negotiation.
Silence is golden: Sometimes saying nothing is not a bad thing, as it might prompt the other side to reveal their cards first.
Making smart connections: It is wise to build a good relationship with the person you’re negotiating with by finding a common interest you both share. Once you have established that relationship, it is more difficult for them to say no to you. This method might not always result in success, but at least working with someone you like is a pleasant thing.
Meet in the middle: Trying to understand the needs of the other person in order to find a compromise for both sides helps to increase chances of success. For example, if your trading partner is not able to accept your offering price, you may try to negotiate for an extension of the warranty period or a discount for bulk purchases.
Make the first offer: In several types of negotiations such as salary negotiations or price negotiations, people often wait for the other side to make the first offer, then negotiate. However, that’s wrong. The first person to make the offer is always at an advantage, as the negotiations that ensue will revolve around the number you are happy with. So do not be afraid to make the first offer. Use this opportunity as a chance to control the negotiation.
Respect the other side: Showing respect to the other side increases your chance of success. For example, by saying “The price for your software is $3,000 right? I think it’s an appropriate price for the outstanding benefits I’m looking for in a software. Unfortunately, my budget is only at $2,000. Is there anything you can do?”, you might be surprised you may actually get the price you offer.
Always listen: It is strange but true. Oftentimes during negotiations, neither side is listening to the other. What you should always do is listen and understand what the other side truly wants, not only by listening to the words they say, but also observing their body language and other types of expressions. This will allow you to understand what they want and arrive at a place you’re both happy with.
