On the release to warehouse screen there is an amount field that you might want to consider how you use this. Essentially it displays the credit limit for the customer order. It might be worth considering how or if you do credit checks before you ship. In this case the field just lists the credit amount for the customer which might not be that valuable to make a decision from.

There is a quick overview.
