Contrary to what you might think, eBay businesses do not have formal business relationships with the eBay corporation, nor do they have to be authorized by eBay. To become an eBay business, all you have to do is start selling on the eBay site. Nothing more formal than a standard eBay membershipin the form of a free Seller's Accountis required.

eBay businesses can be of any size, revenue-wise. Some eBay businesses sell only one item a week; some sell millions of dollars worth of merchandise every year. It doesn't even have to be a full-time thing. Many eBay businesses are part-time endeavors run by people who have other full-time jobs.

What distinguishes an eBay business from the average individual selling on eBay is intent. While individuals tend to sell on eBay because they need the money or want to get rid of old junk lying around the house, eBay businesses sell merchandise that they intend to make a profit on. eBay businesses have to purchase or create the items they sell; they also have to ensure a constant flow of merchandise to feed a continuing schedule of auction listings. eBay businesses sell on eBay every week of the year, not just when it's convenient. And they work hard at it.

And, finally, eBay businesses are businesses. That means they have to deal with the same issues any business has to deal withmanaging inventory, handling customer payments, paying taxes, dealing with complaints, and the like. The people behind these eBay businesses do what they do because they like it, sure, but also because they want to make a profit.
