How to Enable Out of Stock Control for eBay Sales Channels
If you don't want your eBay listings to become inactive when you run out stock, you can enable Out of Stock Control for your eBay sales channel in Extensiv Network Manager. Enabling this setting will keep out-of-stock listings active on eBay while hiding them from search results. When inventory is added again, the active listings will reappear in search results.
