Customer deposit

Hello All,

One of my customer has a requirement, where their customers will pay cash as "Customer Deposit" upfront. They tell the client that they will place sales orders to buy the clients products in the next 6 months. And once they start placing the orders, my client will start deducting money from the customer deposit.

Please let me know how do you implement a solution for this kind of scenario.

I will appreciate the response.

Thanks,

Vishnu
