In my opinion,it will take a time to trade smoothly between your two parties.
But you can try to know your supplier as many as you can before you start to do business.You can email,call,visit...and start a small trial order to your supplier first.If your supplier can follow what they promise,I think they are a good supplier than worthy of your confidence.
