PR Answer:
Although we develop, manufacture and retail goods for the consumer market, we nonetheless consider ourselves to be a service driven company. Those who purchase our products mean more to us than entries on a daily sales report. The purchase is the beginning of a relationship in which we will strive to maintain excellent customer contact, regular product updates and a service that is second to none. The term "client" is more widely recognised to reflect this greater level of service.
Alternate Answer:
I originally named our customer table in the sales database "Clients" and it stuck.
