Customer service is the key to success in any business, and eBay is no exception. If you provide all of the professionalism of a legitimate offline business, respond quickly to bidder and buyer inquiries,
Developing good rapport requires that you address your customers' needs before they become concerns. Your item descriptions should be detailed and should anticipate bidders' questions about your product, company, or services. Display clear photos that fully capture the condition of the item. And always describe your items accurately. An item with a misleading description may sell for a few pennies more, but that modest gain will be far outweighed by negative feedback left by a disappointed buyer.
Make the transaction as convenient as possible; list all terms up front, including shipping charges and return and warranty policies. Provide as many payment options as you can comfortably accommodate. Restricting the ways a winning bidder can pay by accepting only PayPal or money orders, for instance, will reduce the number of bidders and likely reduce the final price of the item.
