I'm doing a gold trading system where a user could buy or sale a gold with the store. To buy a gold, the customer have to register first. Then they place an order for a gold and pay for them with credit card. They would get a receipt that could be used to redeem said gold at any branch. To sell, the system will check if the customer has purchased their gold before. If they didn't purchase enough gold, the system will deny the transaction. For example, if one want to sale 50 ounces of gold to the store but their record show they only 10 ounces the system would deny it.
