The first step in e-commerce after one has established a web presence is to offer products and sell on the web.
Merchant enables a business to offer e-commerce by making their products available through the web.
Existing catalogues can be made into an e-catalogue. An aggregation mechanism that presents goods or services for sale and enables users to buy them in electronic marketplaces. A Web site that maintains catalogs from multiple suppliers. Buyers enter the site, view many suppliers at once and purchase products or services. E-malls often charge a fee for tenancy or membership, may take title to the goods themselves, and are selling environments based on traditional concepts of print and broadcast advertising that entice visitors to buy.
