Any exchange of goods and services, of any kind, for compensation in any form or manner, is incomplete without thoughtful, robust and customer-focused support after the sale. Smart marketers make an emphatic case for their customer service after “the sale” a major part of their marketing pitch. No buyer of anything wants to be orphaned by the seller after the sale. Good marketers make allowances for after-sales customer service to even the most challenging of products, such as short-term consumables and those whose benefits manifest well into the future. Good customer service equals profits.
