Unless you have been living under a rock for the last few years, you have probably heard about e-commerce. And you may have heard about it from several different angles:

• heard about all of the companies that offer e-commerce because you have been bombarded by their TV and radio ads
• read all of the news stories about the shift to e-commerce and the hype that has developed around e-commerce companies
• seen the huge valuations that Web companies get in the stock market, even when they don't make a profit
• purchased something on the Web, so you have direct personal experience with e-commerce

Still, you may feel like you don't understand e-commerce at all. What is all the hype about? Why the huge valuations? And most importantly, is there a way for you to participate? If you have an e-commerce idea, how might you get started implementing it? If you have had questions like these, then this article can help by exposing you to the entire e-commerce space.

Commerce

Merriam-Webster's Collegiate Dictionary gives a few definitions of commerce:

com.merce n [MF, fr. L commercium, fr. com- + merc-, merx merchandise] (1537)
1: social intercourse: interchange of ideas, opinions, or sentiments
2: the exchange or buying and selling of commodities on a large scale involving transportation from place to place
3: sexual intercourse

We tend to be interested in the second definition, but that third one is interesting and unexpected -- maybe that's what all the hype is about?

So commerce is, quite simply, the exchange of goods and services, usually for money. We see commerce all around us in in millions of different forms. When you buy something at a grocery store  you are participating in commerce. In the same way, if you cart half of your possessions onto your front lawn for a yard sale, you are participating in commerce from a different angle. If you go to work each day for a company that produces a product, that is yet another link in the chain of commerce. When you think about commerce in these different ways, you instinctively recognize several different roles:

• Buyers - these are people with money who want to purchase a good or service.
• Sellers - these are the people who offer goods and services to buyers. Sellers are generally recognized in two different forms: retailers who sell directly to consumers and wholesalers or distributors who sell to retailers and other businesses.
• Producers - these are the people who create the products and services that sellers offer to buyers. A producer is always, by necessity, a seller as well. The producer sells the products produced to wholesalers, retailers, or directly to the consumer.

You can see that at this high level, commerce is a fairly simple concept. Whether it is something as simple as a person making and selling popcorn on a street corner or as complex as a contractor delivering a space shuttle to NASA, all of commerce at its simplest level relies on buyers, sellers, and producers.
