I'm a NY company, out of state complany owes money. Do I file for small claims in NYS or in their state?

Im a NY Corp. One of my distributors from out of state is delinquent on paying the balance of an invoice. I would like to bring them to small claims court. I would like to know if I do this in NY or in their state. They have no representation in NY, nor I in their state. Where do I file a small claims suit? And if I have to file there - do I have to appear in their state? As, the total owed is about $900.It would cost me that for the flight and hotel etc. Please help
