You can find the seller center on the Amazon platform, enter the store management page, fill in the relevant information as required and upload the product, and then you can start selling. In addition, you can increase the store's exposure and sales through store agency or marketing services provided by Amazon's third-party service providers. If you want to leave the Amazon platform, you can also sell the store by transferring the store qualification. However, please note that before transferring the store qualification, you must comply with the relevant regulations of the Amazon platform, such as not violating the seller service agreement, otherwise you will face the risk of being blocked.
