When organizations link their buying and selling systems, they are automating transactions between them and therefore shipments of raw materials can arrive at the manufacturer's plant just in time to be used in the production cycle. For example, if a tire manufacturer ships tires before they are needed by the car producers, the tires would have to be doubled handled and warehoused until the assembly line is ready for them. On the other hand, if the tire manufacturer and the car producer had a B2B link, facilitated by the Internet, the car producer's system could alert the tire manufacturer's system when the tires would be needed and therefore they could be shipped just in time to be placed on the cars at the right time during the assemble process.
Here is a list of the main differences between B2B and B2C:

The typical consumer uses e-commerce, which is a small subset of a much larger use of Internet technologies used to run organizations, known as e-business. E-business and B2B systems can be complicated because they must be able to bridge the technologies in different organizations. To give you an idea of the scope of B2B and the possible complexity, IBM just purchased AT&T's T-N Sterling Commerce unit for $1.4 billion. So, next time you buy something on line, you can now appreciate the fact that you are a very small cog in the huge e-business Internet wheel.
