Mirroring can be a great tool to close a sale in a negotiation by creating a positive and productive atmosphere, overcoming resistance and objections, and influencing the decision-making process. To use mirroring effectively, establish rapport by mirroring their greeting, handshake, smile, or small talk. During the negotiation, reinforce agreement by mirroring their positive comments, compliments, questions, or requests. If your prospect raises any objections or concerns, use mirroring to acknowledge and address them. Finally, when you are ready to close the sale, use mirroring to persuade and motivate your prospect by mirroring their goals, needs, preferences, or emotions. This will help you appeal to their logic and feelings and trigger their action and commitment.
