Think of it as a checkbook. From the current Quantity [balance], you have to subtract any product orders received by the client from their suppliers [deposits]. You have to add the net quantity sold to the customers [withdrawals]. This means you have to have a way of tracking, by date, the orders the client places and receives that restock his inventory as well as track all sales and returns by the customers.
