eBay Inventory is located under the Inventory tab from the main Salestio navigation. Salestio will be able to pull the Inventory from the eBay account after you connect your account to Salestio.
Here you can run a search against product title, view product stock and price, check the status and the start date of the listing.
Salestio pulls the Inventory once every 24 hours. However, you can download the inventory from your eBay account manually. To do so, please navigate to the Inventory tab in Salestio and click the 'Download eBay Inventory' button in the top right corner of the page.
