Sometimes called customer services, this is an all-inclusive term that covers different sets of functions for different companies. Historically it has included some or all of the functions needed to service channel intermediaries and/or end customers, such as inventory planning and control; order processing, shipping, and delivery information; product installation, maintenance, repair, replacement, and warranty administration; and answering customer inquiries. Organizationally most of these services are provided by functional departments other than marketing. They may or may not be coordinated by a marketing service manager or customer service manager reporting to the marketing manager. Comment: While the above named services are basic to providing marketing services to channels of distribution and customers, another use of the term applies to a centralized department that provides in-house services to company divisions.
