You also don't get to dictate the suppliers response to stretching them. If you keep stretching me, one day I'm going to be fed up and not send a shipment until you've paid. If you're truly running it tight like many are, you may have been relying on selling that stock to pay for it, shoot that's a bad spot to be in. As I've said in other comments though, keep people in the loop and you'll have a much better time. Communicate first and make decisions based on the outcomes of that. Maybe the outcomes the same, and you don't get sent the goods, that's fine at least you know ahead of time and can react.
