The legal remedies are the same out of the state as in state.  The only real remedy is to sue and I've found from experience that even when you win the case, collecting from a corporation that has gone under is pretty much worthless.  I have always hired a local-to-the-deadbeat collections specialist attorney. Not that it has done me any good!

I've found that fellow vendor managers are the BEST payers, not the worst.  It's the big companies where I have to pull teeth to be paid in a timely manner.  They're so huge, that the buck keeps getting passed and ends up sitting on someone's desk until the NEXT time I raise a stink.  The nationwide companies -- based in the U.S. -- have never been a problem.  (And I've been a corporation for 15 years, an LLC before that, and an independent before that.)  I couldn't survive on in-state clients, although I have a wonderful state-wide title company I work for.
