MC2 Software - Credit Limits

We just had a demo of the MC2 Credit, Collections & Deductions software (
www.cforia.com) and our accounting guys got excited over the visual aging 
screens, which says a lot because I usually need to take their pulse!

But our main reason for looking at it this software was to have the 
ability to stop a shipment (in the picking process) if the customer failed 
to meet credit criteria as defined by us.  We're not interested in 
preventing a customer from placing and order, just us from shipping.

So while the software looks great, and the sales guy promises it will do 
exactly what we want - I was hoping to get some feedback from the ML if 
anyone was using it.  Or if they decided not to use it!

I can't make the Chicago show, so I gotta due my homework here!

Thanks in advance for your input, feel free to send direct.
