Quoting from [The Jeco]:
In simple terms your customer wants this:He has an agreement to purchse products from you. He will make the sales in whatever country he is in (US or Europe most likely)... When he sells a unit of whatever product he wants YOU to do the shipping to his customer. he will ONLY pay you on a per piece basis. He will not guarantee any minimum order qty.
Most likely this person has not much experience with selling as no serious person asks someone to drop ship from another country as it is not economic that way. and the Supplier (meaning you) takes all the hassles rather than the person making the bigger profit..... I personally would politely decline the offer.
