How are sales being transformed? It’s not easy for sellers today. The competition is crazy. Calls irritate customers. They sometimes don’t access their email for weeks. Social networks and instant messengers have taken up space on their phones and computers. WhatsApp or Facebook Messenger are convenient, simple, functional and always at hand. What you need for successful sales! The time has come for multi-channel work with clients, the time for a fine combination of calls, letters, live meetings and communication in instant messengers and social networks. Sales by correspondence - this is not about the future, but about the most relevant time in the world - about today. And these sales are far from being as superficial and easy as it may seem to sellers who are accustomed to sending harsh commercial offers or masterfully building a telephone conversation. Learn to properly use instant messengers and integrate correspondence into your daily work with clients!
