An ICP (Internet commerce provider) is a company that sells software and services that enable a merchant with a Web site to build an online store on the merchant's own site or on the provider's site. Products and services can be pre-packaged or customized or some combination. Typically, a pre-packaged ICP product lets a merchant set up an online store using one of several design templates, arranges for secure credit card transactions, and provides order tracking. An ICP may also provide services related to order fulfillment, such as shipping and customer relations.
Some Internet access providers (IAP) and Web design shops also act as ICPs, offering customized services or serving as a vendor of packaged products.
