The fact that I think the method is atomic signals that we should use a Service [Evans DDD] instead to make the whole thing more explicit.The Service could check the current debt and therefore be used proactively by the Order at good places in time.It could also be used pretty much reactively at save time,and some sort of request could be put on a queue and be used reactively after save.The Service would probably use the same Repository method as was just discussed,but that's not anything the caller needs to know,of course.
What should it do reactively after the save?Perhaps move the order to one of two states so that when the user stores an order,it goes into state NewOrder.Then the Service kicks in and moves the order to state Accepted or Denied
