Professional selling plan

Important: When you sign up to sell on Amazon, you are automatically enrolled in the Professional selling plan.

In the Professional selling plan, you pay a nonrefundable monthly subscription fee of $39.99 regardless of whether you list or sell anything. You don't pay a per-item fee when an item sells. All other fees are charged as applicable.

The Professional selling plan gives you access to inventory tools to upload batch files and manage your orders through feeds and reports. These tools are beneficial to most medium- to large-size businesses.

For more information on what features are included in the Professional selling plan, see Selling plan comparison.

Note: If you want to downgrade from the Professional selling plan to an Individual selling plan, you can login to your Seller Central account and switch you plan on the My Services page. For more information, see Switch to an Individual selling plan.

 

If you do not want to switch your selling plan, you can cancel at any time. For more information, see Close your seller account.
