Hi, At the moment it is possible to create collection letters for customers that have an overall negative balance. Example: Transaction 1: Customer invoice for $1000 and a due date 01 April Transaction 2: Credit note for $1500 and a due date 06 June If you run the collection letter process with a cut off date 31 May, the customer will receive a collection letter even though his overall balance is negative (-$500). Would be great if you can create a parameter that allows us avoiding to send out collection letters in this case. Many thanks, Ludwig
