A certain amount of deposit is required to open a store on the Alibaba platform to ensure that the merchant operates in good faith and abides by the platform rules. The deposit can be regarded as a trust guarantee provided by the merchant to the platform, and it can also compensate for the losses that the merchant may cause to the platform. The amount of the deposit varies slightly depending on the type of store, generally ranging from a few hundred to a few thousand yuan. If the merchant does not violate laws and regulations during the operation, the deposit does not need to be refunded; if there is any violation of laws and regulations, the deposit will be used by the platform to compensate the losses of the relevant parties.
