I shipped thru ups. I created the shipping label as a guest. So the autogenerated invoice is no more obtainable. Emailed a pdf copy of generic invoice which ups emailed me which i filled with hand.Yes .. I did that before they even asked me for one and they responded back stating it was needed in my case.. If you used Fedex then you'll have the option to generate commercial invoice online, under Fedex shipping manager
