E-commerce

Ecommerce (e-commerce) or electronic commerce, a subset of e-business, is the purchasing, selling, and exchanging of goods and services over computer networks (such as the Internet) through which transactions or terms of sale are performed electronically.

TYPES OF E-COMMERCE TRANSACTIONS

Business-to-Business (B2B)	Companies doing business with each other such as manufacturers selling to distributors and wholesalers selling to retailers. Pricing is based on quantity of order and is often negotiable.
Business-to-Consumer (B2C)	The Business-to-Consumer type of e-commerce is distinguished by the establishment of electronic business relationships between businesses and final consumers. It corresponds to the retail section of e-commerce, where traditional retail trade normally operates.
Collaborative commerce (c-commerce)	business partners collaborate electronically
Consumer-to-Consumer (C2C)	Consumer-to-Consumer (C2C) type e-commerce encompasses all electronic transactions of goods or services conducted ​​between consumers. Generally, these transactions are conducted through a third party, which provides the online platform where the transactions are actually carried out.
Consumer-to-Business (C2B)	In C2B there is a complete reversal of the traditional sense of exchanging goods. This type of e-commerce is very common in crowdsourcing based projects. A large number of individuals make their services or products available for purchase for companies seeking precisely these types of services or products. Examples of such practices are the sites where designers present several proposals for a company logo and where only one of them is selected and effectively purchased. Another platform that is very common in this type of commerce are the markets that sell royalty-free photographs, images, media and design elements

For me, I prefer http://www.elsajida.com because for me, this B2B e-commerce more cautious and safe to use and give personal information. Otherwise, this is easier because ordering process through online. The inventory is update online, so, when I ordering, I can know which items are already sold out.
