Generally speaking, this is the customer's breach of contract, paying the advance payment, indicating that the goods are needed, and letting your supplier do the production, packaging, stocking and delivery work. If the customer doesn't order the goods halfway, it will cause losses to your supplier, so this advance payment can't be refunded. If he doesn't pay the advance payment, you won't be busy with these things, will you As a customer, he should also know that what they are doing is a breach of contract. If they pay the advance payment, they don't want the goods, which hurts the supplier army. It is unreasonable to ask for this advance payment again. I don't know if there is an agreement in your's contract, but there is such an agreement in general. This is my opinion. Furthermore, as long as it is determined that the customer has breached the contract, the contract termination clause can be executed immediately! Details can be consulted by a lawyer to reduce losses!
