I'm not 100% sure what you mean. I and nearly all sellers on Ebay require payment before sending the item.
For me the frustrating thing is that occasionally the winner of the auction doesn't bother to pay. Sure I've still got the item, but I have to then go through the time consuming process of getting my Ebay fees refunded from Ebay.
That's the main reason I've stopped selling outside the U.S. and Canada. I found too many people who never bother to pay.
