If you want to open a store on eBay, the first thing you need to prepare is to register an eBay account so that you can make formal transactions on eBay. Once the account is registered, you can perform more operations, such as opening a store. In addition, you need to prepare information related to the store, such as the store name, payment method, return policy, etc. Next, you must prepare the details of the goods, including brand, size, quantity and price, as well as pictures, so that buyers can better understand your products. Finally, you also need to prepare customer service information so that buyers can clearly understand how to contact you, so that they can get timely help when they encounter problems and get a satisfactory shopping experience.
