Do manufacturers authorize or prepay medical devices first? Can I return it if I pay in advance? Please let us know the details. Thank you.

Generally, when there is demand, the manufacturer first authorizes the agent, and after the agent negotiates with the customer, the manufacturer is required to pay the order advance payment. After the goods arrive, the agent should pay the full amount of the manufacturer (excluding the warranty, that is, the fault should be solved in time during the warranty period, otherwise the agent can use the money to ask a third party to solve it). Generally speaking, the advance payment is non-refundable, unless the contract cannot be fulfilled due to the manufacturer's reasons.
