Hi, we have a WP LMS (WPLMS) on our site which we have been using for years. It also allows us to credit points or assign $s to students once they completed a course. We have been trying to create a system where this amount can then be deducted from and invoice at checkout. The system my programmers have come out with has been clunky and unreliable. In my mind at checkout it would simply look at teh available balance and then deduct from the "bank account" of earned funds if they in fact have funds available. Does anyone have some experience with this? I know we are talking two different programming languages but if anyone has a good system that worked for them, I would sure appreciate being pointed in the right direction.
