A few days ago I had my first non-payer when I listed a Tiffany & co. bracelet, so I've decided to write this guide for people who have come across the same problem, and to show you what to do after it happens in 4 easy steps (most of the guides on eBay tell you how to avoid them). I've also found that this seems to be more of a problem now that sellers are unable to leave neutral or negative feedback, so I hope these steps will help you! :)
1. Send the bidder invoices (I sent them once a day when they hadn't paid within the first day).
2. If they haven’t replied (Send the bidder a message explaining how he/she needs to pay for the item for you to send it, and that failure to do so could result in their account being suspended.
3. If still no reply or payment, file an Unpaid Item dispute. For some items you can file this straight away, but for others (like my Tiffany & Co. bracelet) you have to wait 7 days. If the buyer fails to respond to the dispute, any negative or neutral Feedback they have left for that item will be removed. At the end of the dispute process, you'll be able to request a Final Value Fee credit, and issue an Unpaid Item strike to the buyer. If a buyer receives multiple strikes they may be suspended.
4. Relist the item. You may want to block certain bidders from bidding on your items - such as ebayers with unpaid item strikes and with feedback less than 5.
Hope this helps!
