eBay sellers can really be divided into 2 main categories:
1. Those sellers who just wish to auction off a few items for some extra cash
2. Those sellers who wish to start and build an eBay business, to generate a regular, perhaps even full-time, income.
If you are in a latter group, you should definitely take at eBay business solutions. The thing to remember is that eBay's success depends on the success of its sellers, and eBay wants to help sellers like you at every turn. One of the way that eBay offers that help is through eBay Business Solutions.
Perhaps the best known, and one of the better solutions for eBay business owners, is eBay Stores. An eBay store allows you to list multiple quantities of the same item, and to keep them listed for longer time periods. Additionally, eBay Store owners also enjoy lower auction fees, and have access to advanced merchandising tools.
The next step up from an eBay Store, and one that you should ever be aiming toward is an eBay Pro Store. An eBay Pro Store will allow you to customize your storefront with your own brand and web address.
As well as stores, there are also many other eBay Business Solutions. These include seller tools, the eBay solutions directory, and the merchant solution center. All of these are useful to many businesses, and they are worth looking at, but do not try to bite off more than more you can chew in one go. Start with your very own eBay store, plan to ever grow into an eBay Pro Store, and go from there.
