An Alibaba store sub-account refers to a sub-account under the Alibaba platform main account, which has independent operating permissions and can manage the store independently. By creating a sub-account, the main account can assign store management tasks to employees in different roles such as store operators and finance, which facilitates team collaboration and permission management.

On the Alibaba platform, the main account refers to the corporate or personal account that registers an Alibaba account, while the sub-account is an account created under the main account that can be used for store management.
