Reports for Payment Schedules

Hi,

Is anyone regularly using payment schedules for ticket orders, and if so how are you keeping track of which customers have a payment schedule running?

We have a music school with fees paid through TNEW. Customers can pay the full amount up front, or they can select a weekly or monthly payment schedule. Our problem is knowing when a customer has selected a payment schedule, and what the payment dates and amounts are. We need to provide this info to an outside organisation so can't give them access to the application; we need a report that shows the dates and amounts for all payment schedules (past and future) for a specified Production Season or Performance.

Any ideas?
