Let me give you a few more details.  We use the desktop version of Enterprise Solutions 19 rev. R5.

We have many customers who charge purchases on their customer account which they pay at a later date after we email or mail statements to them.  We charge a finance charge to these customers if they do not pay their bill within 30 days of their invoice date.  It is a percentage that is allowable by law.  We create an Invoice for all sales.  None of which are recurring.  Customer sales and invoices are tracked through their individual customer account.  All of these sales are kept under accounts receivable.  

When a customer becomes delinquent beyond our ability to collect the balance due, we turn the account over to a collection agency to assist in collecting the account.  At the time this happens we can no longer assess finance charges or send out statements.  

I have found that if I mark "none" in their customer account - payment options and when I print statements by "payment options" it will not generate a statement.  But I have yet to find any method to stop the system from assessing finance charges except by me manually telling it not to in the assess finance charges window.  This is very cumbersome and because we have hundreds of customers it is quite difficult and time consuming to review all our customers when applying finance charges.

I am looking for another way to mark certain customers to stop applying finance charges.  

Pretty simple request -- just not finding a method yet.  

Can you help?
