Add refund capability to the customer, and in fact only the customer, as we've revoked refund capability from the lease. This is to help work through various issues surrounding use of security deposits and general refund functionality. For example, a customer who has overpayed (customer surplus, with zero balance on lease), and then moves out. Where that security deposit surplus goes has been a bit of a thorn. Hopefully, this resolves the issue, although there may still be some bugs to flush out.
