What do I do if a buyer doesn't pay?
If payment hasn't been received within two or three days, a friendly reminder is often all that's needed. If after
four days you've not received payment and had no contact from the buyer, you can file an Unpaid Item Dispute
(UPI) with eBay. eBay will then step in and contact your buyer to request payment for the item.
If a further four days pass with no payment received, then you are free to close the dispute.
You should then
get a refund on your Final Value Fee (FVF) from the sale, and the 'buyer' will be issued with a non-payment
strike, and will be prevented from leaving feedback. If they receive too many non-payment strikes, then they will be suspended from eBay. You can also set your Buyer Requirements
block users who have a number of non-payment strikes, amongst other things.
Where to find the payment
dispute console - click the link above, or go to the eBay Site Map
then under Selling Activites/See All Selling Activities, choose 'Report An Unpaid Item'.
