Customer service: is an important element for providing significant value added benefit to the supply chain in cost-effective way and making a successful business. You can have a wonderful product, but without excellent customer service, the item will never be purchased. The customer interacts with a company through a number of channels and the level of service that is afforded the customer goes a long way to achieving customer satisfaction and in turn more orders for the company. Many companies think that their only contact with the customer is through the sales and marketing staff, but this is no longer the case. The customer interacts with other departments such as shipping, quality control, accounts receivable, or a repairs service. Each of these departments must offer the same high level of customer service in order to maintain excellent customer satisfaction. The customer will also interact with a company through its online presence, either a website where they can buy products, or check on shipping, or through social media. These instances also require that the customer receives the highest level of customer service.
