In the Business world there is a strong emphasis on how you communicate and build relationships with clients. in doing so you then can use that as a reference point, and maybe help them be a part of promoting your business. as you build relationships you learn to grow your clientele.
On this webpage they describe client or customer service in 3 points: “Performing Tasks for Clients, Developing of Products for Clients, Maintaining Products for clients, and Performing information and advice to clients.” Each client is different, but as a general rule you will be providing one or more of these things to a client, or customer. This page also described the importance of personal relation to the client. “The easier you make it for clients to personally interact with you, then the more aware and willing they will be to engage you in business activities.” this is a simple way to engage clients, and learn about them is through personal relations before the business interactions.
