To sell on eBay, you'll need an eBay account. If you don't already have one, you'll need to register. You can choose between a personal or business account.
If you plan to sell casually, like selling items you no longer need or want, a personal account is the best option. Pick a business account if you want to sell large quantities, or have items that you've made or bought to resell.
To create an eBay account:
Navigate to the eBay site on which you want to register (eBay sites below)
Go to the Registration page and select Personal account or Business account
Enter details and register
Click sell at the top of any eBay page to guide you through listing a product
Selling Limits
eBay imposes selling limits, which are quite low on newly registered eBay accounts. Please see Selling limits for more information including instructions to request an increase.
If you wish to sell on multiple ebay marketplaces globally, you can do so with Marketplace Connect directly from Shopify's all-in-one app
