How much deposit do I need to pay for custom jewelry from a jewelry factory

W: My friend opened it. I want to ask him to customize a batch of accessories. I know that custom accessories require a deposit, but I don’t know how much to pay. If I ask my friend directly, he will definitely not say, let alone Yes, but since I have chosen the item of jewelry, I should abide by the rules of the jewelry industry, so please tell friends who know how much should I pay? D: As a friend, you generally don't need to pay a deposit, but since you separate your friends from the business, it is enough to show that you are a person who really knows how to do business. The jewelry factory collects the deposit, one is to confirm the order, and the two parties must be responsible for the order; the other is because some orders are indeed too expensive, and the jewelry factory collects the deposit to meet normal expenses. There are industry standards for receiving a deposit. Generally, a 50% deposit is charged for custom-made silver jewelry, which is equivalent to a fee for purchasing silver; a 30% deposit is generally charged for custom alloy jewelry, copper jewelry, etc. The information comes from the Internet, please contact if the infringement is involved.
