To be able to set a limit, in the contact form, so that the sum of the outstanding due dates plus the orders that are placed in new ones does not exceed it, unless it is accepted. A warning message should appear giving the option of accepting or not placing a new order given that it exceeds the commercial risk limit given to a customer.

An example would be a customer who has a limited business risk (entered by hand in a box) of 50,000e. And that customer has undue, outstanding payment, 40,000 euros. If you place a new order of 15,000 euros, the system should notify you that you have overcome the risk, and in this case accept or not place the order.
