We are going to be offering a new type of service with some of our products. Two of the services will be generating an "amount off of invoice" which is creating a problem, as they are amounts that are negative.

When we try to enter a new item in our inventory, that has a negative amount as the base price, we get a warning that says "Value must be between 0.00 and 9999999.00

Is there a way to enter a new product code with a negative amount?

Thank you.
