After-market refers to any market where the customers who implement one product or service are likely to purchase a related, follow-on product. For example, customers who install a software package will constitute the after-market for software support services. The existence of an after-market is often a persuasive argument for manufacturers to stay in direct contact with end-users. Manufacturers will use postage-paid guarantee cards, for example, to keep track of the address of end-users.Aftermarket service includes support for warranties, contracts, and parts sales.
