Ticket Order Billing Question

When running the Ticket Order Billing Utility (in Test), we are getting the full report showing all people who should be billed.  However, when running this in Test (this is our first time doing this), it looks like none of the orders reflect their 2nd payment.  We required a downpayment at the time of their order, so this would be their 2nd payment.  Would this have anything to do with Test not actually charging cards?  If we ran this in Live, would those payments automatically apply to the order?  If so, does it happen immediately or when the batch posts to Transcend at the end of the day? 

Sincerely,

Christy (Very nervous to hit the button) Warren
