The death to most negotiations is the painful "I need to think about it" response. In other words, you will never hear from that person again.
In addition to the Yes-No Strategy I shared above, you can also prevent this by starting the negotiation with an agreement to the outcome first. Explain to your prospect that it is important they have every answer 3D Rendering Services they want to reach a decision. Continue to explain that you have found that if they "need time to think about it," that indicates that they don't have the information necessary to make a clear yes or no decision. To stop it from happening, ask the prospect if they agree to concluding this negotiation with a yes or no decision (like in the strategy above) or if they can share with you what their exact plan is if they aren’t able to make a yes or no decision.
