We are pleased to announce that the Frooition listing tool now supports the new eBay Out Of Stock Control feature. Historically GTC (Good ’til cancelled) items were removed from eBay when their quantity reached zero, resulting in sellers having to create new items once they had restocked. By using the eBay Out of Stock Control functionality sellers can keep their GTC items alive, even when the quantity reaches zero. Items that have no quantity, which are therefore unavailable for purchase, are removed from the eBay search results but continue to keep their listing page to advertise themselves to buyers. This feature is useful when sellers are waiting for stock of an item. Instead of ending the item and then recreating it when the stock arrives, sellers can use this feature to instead hide the item. When the stock arrives in stock simply revise the item quantity and the product is available for purchase!
Why use eBay Out of Stock Control for your listings? The item retains the same item number The item’s listing page is kept live The count of items sold is preserved The item is not removed from any buyer’s watch list Exposure to other search engines is maintained Sales history is retained – helping you with your best match ranking The Out Of Stock Control is not available via eBay’s listing tool (sell your item page). Sellers can only make use of it through third parties that have implemented it, including Frooition. As a certified eBay provider, Frooition have made this functionality available to all users of our listing tool: In addition, users who subscribe to the Frooition Bulk Revision tool have the ability to add this functionality to existing live eBay items. For more information on how to use the new functionality please see the Knowledge base article.
