Manual Quantity Sync
To sync quantity available onto the Marketplace, select one or several listings on the "Listings" page, and press the "Sync Quantity to Marketplace" button.
Once you push the button Teapplix ActionShip will automatically sync the quantity available on the selected listing to the marketplace. Note that certain type of listings, like FBA, eBay auctions, etc, do not accept quantity updates and will be skipped.
Max Quantity for eBay Listings
This option is setup under Inventory => Options and only visible when you have eBay accounts linked to ActionShip.
Once a non 0 number is set, ActionShip will post actual inventory quantity to eBay if it is below the max, or the max if actual inventory is greater to the max.
