Sadly these days it is something that almost all eBay store owners will experience at some point but for those new to eBay store ownership receiving a charge back notice, sometimes months after an item has been sold and shipped can be quite a shock. Unfortunately many of these newer store owners (and even some experienced ones)really do not know how to handle the situation and simply resign themselves to the loss.
Dealing with a charge-back on a purchase made through your eBay store is not an easy task but if you feel the reason for the chargeback is an invalid one (and it happens far more often than you might think) then you should try to take the time to appeal it not only to protect the money that really should be yours but also to (hopefully) discourage the buyer from doing the same thing again to another eBay seller.
There are legitimate reasons for a chargeback you may have to swallow. If a credit card has been used fraudulently to purchase items from your eBay storefront then the rightful owner’s credit card company will charge the items purchased back as a matter of course.
There is very little a seller can do about this other than make a mental note to improve their own verification procedures in the future, implementing things like refusing to ship to an address that is not Paypal verified or to an address that is different from a billing address and making use of some of the other eBay store tools that can help you vet buyers before you agree to make a sale.
An increasing number of people though are abusing the chargeback system, usually by claiming something was wrong weeks, or even months after the sale was made. This should always raise a red flag – why wait so long to complain?
One of the biggest reasons people give when making this late chargebacks is that the item was not as described. However if you follow the standard good practices of any eBay store owner and include actual photographs of the items being sold rather than stock catalogue pictures and you make use of the seller condition comments in the right way you should have a good case against this kind of chargeback if you feel the claim is false. It will just be up to you to make that case rather than to accept the loss.
