event sourcing and the notion of compensating transactions go along way in solving these types of problems.

I did a find for 'event sourcing' in this thread and yours is the single hit at the time of my comment. I came here to agree, and tell the OP that you indeed would benefit from an Event Sourcing Architecture.
