how does ebay unpaid item assistant work?

I have searched and searched for this on ebay, without much luck. If one opens an unpaid item case...what happens next? How will I know when I can relist the item, assuming the buyer never does pay??

When there's a problem with a transaction and the buyer doesn't pay, Unpaid Item Assistant can save you time and effort. Unpaid Item Assistant automates the process of opening and closing unpaid item cases. You can set it up to automatically open a case after a specified time—4, 8, 16, 24, or 32 days after the listing ended.

Then after the case is opened, the buyer has up to 4 days to pay, and when they do, the case closes automatically.

If they don't pay, the case closes automatically, you get a final value fee credit, and the unpaid item is recorded on the buyer's account. You can then relist your item at any time.

If you'd rather open and close cases manually, you can in our Resolution Center. Or, you and the buyer can agree to cancel the transaction.
