Effective communication is vital for sales management and closing deals. Communication refers to the exchange of information between two or more people, and is effective when the message is clearly received and understood. Good communication skills in sales include making eye contact, active listening, and speaking clearly, while bad skills are looking away, interrupting, and mumbling. Communication improves client relationships and sales effectiveness, boosts employee confidence, and increases goodwill. To improve communication, salespeople should keep their pitch simple, be aware of their tone, listen without interrupting, be transparent, stay calm, and include warm greetings. Mastering communication skills can increase sales success tenfold.
