Problem:
According to marketingprofs and other online and offline sources:
B2B (Business to Business) site secifically caters one busines to another business. Usually providing inhouse service or maitanance software/networks for other businesses to utilize in order to increase function, marketing, sales, profits, efficiency and the like. Examples: Microsoft.com, Macromedia.com, Marketing sites, crmguru.com, basically anything targeting business owners, managers, and decision makers.
B2B refers to the economic connection between business and business. This means that a company that uses the Internet for ordering from its suppliers or making payments already takes advantage of e-commerce.
B2C (Business to Consumer) site specifically caters to a group or target consumer in order to expose, sell, market. etc goods or services to the public. Examples: Amazon.com, ebay.com, Walmart.com, Borders.com, basically anything offering a retail product to the public in the form of a virtual store.
B2C electronic commerce comprises commercial transactions, involving both organisations and individuals. From the technical point of view e-commerce is the processing and transmission of digitised data. E-commerce decreases the distance between producers and consumers. Consumers can make their purchase without entering a traditional shop.
MARKETING DIFFERENCES:
The difference in marketing is that a B2B "seller" tries to differentiate itself from its competition by marketing its value proposition to its target market as one that will save the "buyer" companies a great deal of time and money by automating as much of their supply chain as possible. They do this through the traditional offline methods of advertising, tradeshow, field sales etc. along with websites that provide customer only access to their accounts and inventory. In addition, e-mail marketing and other communications using the supply chain channels is effective.
Establishing strategic partnerships and alliances can also provide tremendous synergies and leverage.
B2C also uses traditional offline methods along with the integration of online tools such as interactive websites, email marketing, online communities, CPC (cost-per-click advertising such as Google AdWords) pop-up and banner ads etc.
