I have seen a plugin named “Partial COD” which restricts the creation of fake COD (Cash on Delivery) orders by charging customers a partial amount at the time of purchase for building authentic order confirmation. It creates genuine COD orders and provides reliable customers to the owner.

If you applied this plugin in your woocommerce store, the customer has to pay a certain amount for any order, which will confirm that the customer is genuine or not.
I hope you will get the help from this.
