Are you sure you are talking about using a DDA account? Is this one account or does every customer have one? I'm soooo confused?
Is this account only used for this purpose, or can they make other deposits and write checks on the account?
What happens on the normal payment due date when the customer doesn't make a payment?
I can't help it - I have to keep asking question - your management is now making me crazy - there has to be some redeeming factor here that we are missing.
