Make sure your listing follows these guidelines. If it doesn't, it may be removed, and you may be subject to a range of other actions, including limits of your buying and selling privileges and suspension of your account.
What are the guidelines?
Some business-related items are not "investments" and may be listed on eBay. Here are some examples of items that can be sold:
100% of the assets of a business (inventory and plant) where no transfer of stock is involved
Information about how to start a business
Any sale of inventory or fixtures
"Turn key" businesses, such as vending machines or windshield repair kits
Examples of stocks and securities that are restricted on eBay:
Collectable stock certificates must be cancelled or represent an interest in an entity that no longer legally exists and can't be redeemed for cash or securities in any other company.
Examples of stocks and securities that aren't allowed on eBay:
Documentation that represents proof of a current investment interest in any entity; for example, stocks, bonds, or investment interests. This includes, but isn’t limited to, corporations or partnerships.
Credit. As an example, you can't sell £1,000 in credit.
Solicitations to invest money in any business venture.
Any ongoing business if the sale involves a transfer of any shares or interests in shares or any loan stock or other form of indebtedness in that business.
