Credit Checking

Hi,

I am working on 11.5.10.2 order management , my problem is many customers havent paid order outstanding amount example more than $100.

I am looking for any option that will put customer order on hold if tghey have any outstanding amounts.

How to do this should I write custom code on booking event or there is a check box="Credit Check" on payment term if I enabled this where should I deifine amount ?

thanks,
