Hello,
At the moment if a credit exists for a customer the first reminder we receive is when processing a payment, it would make more sense (to me) if the warning came when the invoice was raised otherwise that horse has already bolted, if advised earlier an adjustment by way of the credit would reduce the invoice at that point and the credit issue is resolved. As it stands if its missed and not picked up it can continue invoice after invoice, and it would be a better solution than sticky notes on the screen to remind of customers with credits.
"Warning that a credit exists when raising invoice"
