Business on the internet is often referred to as E-Commerce. Some people do business completely through e-commerce. Their customers come from the internet, they do all their communication on the internet, and don't need a real-world store do do any business.
More commonly, businesses have both a storefront and an internet presence. This is often referred to as limited e-commerce. Think of stores you shop at who also maintain a web presence where they can take orders. This is a good example of limited e-commerce.
Almost any business, from large corporations to individual freelancers, benefit from a web presence. A website is a sign of your professionalism. It can be there just for the information value or, ideally, it can be designed to generate leads. A presence on the web shows that you understand today's technology and the customer's need for information. A good website shows customers why they would benefit from working with you.
If you want to be involved in e-commerce, the first start is finding a good e-commerce webhost. With a good host you will be able to set up a site easily and find many options for making your site stand out. It should have auto-responders for your clients, an easy way to make a purchase, and several options for payment. Even if you are only selling one product you want to make it as easy as possible for the customer to buy it.
People turn to the web for almost everything today. If you are not on it, you should be. It's time to start using e-commerce.
