We're making the process for handling unpaid items easier for both buyers and sellers.
Automate claims with the Unpaid Item Assistant

The Unpaid Item Assistant automatically opens a case if your buyer doesn't pay after a period of time that you specify - 4, 8, 16, 24, or 32 days after the listing closes. If four days pass without payment after the case is opened, the case will be closed, your Final Value Fee will be automatically refunded, the buyer won’t be able to leave Feedback, and you will be able to relist your item.
If you're using Unpaid Item Assistant, it automatically blocks Feedback from buyers who haven't paid. As soon as it opens a case, the buyer won't be able to leave Feedback on your transaction until the case is closed and you've received payment.
The Unpaid Item Assistant is available for all listing formats offering PayPal as the only payment method and buyers must have gone through eBay checkout or a third-party listing service that uses eBay checkout.
To take advantage of the Unpaid Item Assistant you must opt in by following these steps:

• Go to "My eBay" at the top of any eBay page.
• Select the "Account" tab at the top of the page.
• Click "Site Preferences" on the left.
• Go to your "Unpaid Item Preferences."
• Select the option that says "Yes - I want Unpaid Item Assistant to open and close cases on my behalf" and set the day-4, 8, 16, 24, 32.
• Click "Save."

Please ensure you remove local pick up, checks and postal orders as payment options from all your listings, since this automated process only works when you list PayPal as the only payment option.
Improvements to the process when you open an unpaid item claim manually

• If a buyer doesn’t pay and you cancel the transaction, the buyer will no longer be able to pay for the item.
• If you open an unpaid item case, it will be closed automatically when the buyer pays with PayPal.
