Implemented refund, at least for the most part. Minor testing, but looks promising. Because of this change the customer account entries grid appears odd, with a refunds showing up as a 'Charge'. So, I'm toying with the idea of having entries show up as customer 'Debits' and 'Credits'. I don't know if this will cause user confusion, but we'll play with it for a while and see. It actually reminds me a bit (coming full circle) of the earliest implementations, which kept track of a lease on its own account/ledger, in which credit/debit would be the exact correct terms.
