After-sales is the provision of services, support and spare parts after making an initial sale. This often occurs in the provision of complex machinery which requires regular maintenance such as motor vehicles.Customer service is the provision of service to customers before, during and after a purchase. The perception of success of such interactions is dependent on employees "who can adjust themselves to the personality of the guest". Customer service concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization or may proactively interview customers for feedback.
From the point of view of an overall sales process engineering effort, customer service plays an important role in an organization's ability to generate income and revenue. From that perspective, customer service should be included as part of an overall approach to systematic improvement. One good customer service experience can change the entire perception a customer holds towards the organization.
A customer support is a range of customer services to assist customers in making cost effective and correct use of a product. It includes assistance in planning, installation, training, trouble shooting, maintenance, upgrading, and disposal of a product. These services even may be done at customer's side where he/she uses the product or service. In this case it is called "at home customer services" or "at home customer support".
Regarding technology products such as mobile phones, televisions, computers, software products or other electronic or mechanical goods, it is termed technical support.
Customer service may be provided by a person (e.g., sales and service representative), or by automated means[citation needed]. Examples of automated means are Internet sites. An advantage with automated means is an increased ability to provide service 24-hours a day, which can, at least, be a complement to customer service by persons.
Another example of automated customer service is by touch-tone phone, which usually involves a main menu, and the use of the keypad as options (i.e. "Press 1 for English, Press 2 for Spanish", etc.)
However, in the Internet era, a challenge has been to maintain and/or enhance the personal experience while making use of the efficiencies of online commerce. "Online customers are literally invisible to you (and you to them), so it's easy to shortchange them emotionally. But this lack of visual and tactile presence makes it even more crucial to create a sense of personal, human-to-human connection in the online arena."
