How to put a limit for each invoice amount for a customer.

Hi,

Please may you help us on the below issue.

We would like to put a limit for the invoice amount for many of our customers, so is there any

way to execute this.

Suppose we have a Customer "AA" and we would like to have invoices for this customer are

not exceed the amount 10,000.00 USD for each invoice.

So how to perform this scenario ?

Thanks

George
