In sales, immediate communication with your prospects and current customers is important. Being available to answer questions or further negotiate a deal allows your clients to feel secure and more apt to purchase from you. But what if you can’t answer the phone when they call? Make sure you have a voicemail system set up so your clients have the opportunity to leave you a message.
