After finding a product that is being dropped, you can order it with your own account and pay for it. Fill in your customer's delivery address as the delivery address. Then when Alibaba drops the product, it will be sent to the customer according to the address you left. To put it simply, the customer buys your product---you buy the supplier's product---the supplier sends the product---the customer receives the product from the supplier---the customer confirms receipt---the funds are transferred to your account---you confirm receipt and order the product from the supplier---the transaction is completed.
