That's been my experience, just the threat of turning it off has a way of unblocking the system. I usually start with the users of the system who are often as frustrated with the system as we are.

Having said that I mostly don't offer credit terms anymore, my average order value is about £500 which means it isn't worth the time spent chasing late payments. In 99% of cases the customer will find a way of paying upfront.
