Basic Definitions

The interaction of business with customers does not end after the product is passed to the consumer and the payment is received from the customer.

Modern products are becoming more and more complex, and customers need additional help with using the products. Various customer services perform this function, for example, installation services, training to use the product, maintenance, repair, and even recycling.

Sometimes, customer service begins even earlier, at a stage when somebody is only going to purchase the product. Today, rapidly developing services help customers find and choose a suitable product, learn about its features, advantages and disadvantages, etc.

Customer service is especially important in cases when the customer gets a service as a product.
