Alibaba's buy now, pay later (i.e. "cash on delivery") transaction method refers to a transaction method in which the buyer pays after receiving the goods and confirming that they are correct. For this transaction method, Alibaba will charge the seller a certain service fee.

Specifically, when using the cash on delivery service, the seller needs to pay a certain percentage of commission or handling fee to the Alibaba platform as the cost and fee of receiving the service. The amount of the commission or handling fee may vary depending on the product category, transaction amount and region, and is usually automatically deducted from the transaction income. At the same time, it should be noted that when using the cash on delivery service, the seller needs to meet certain credit rating and risk control requirements to ensure the security and reliability of the transaction.
