When an invoice for a sales order is delinquent, we have a process where we create a separate charge invoice for the penalty and interest fees. We run billing operations to create the charge invoice then use an advanced PDF form to produce the "printed" invoice. We had a couple of charges that were the incorrect amount. I deleted the invoices thinking we could create a fresh charge invoice but the charges themselves still exist. Is there a way to delete them? I appreciate any recommendations on how to handle this.

These are charges based on a customer transaction. They are not associated with project billing transactions.
