While working in ShipStation, you might have seen the Restore button in the "Shipped" orders view. This button is for orders you may want to move back to the Awaiting Shipment view on the orders tab.
To Restore an order, you'll need go to your Orders tab, then into the Shipped view. Select the order(s) and then click the Restore button at the top of the page as shown above.
This option can be helpful if you've accidentally marked an order as shipped, or need to indicate to your warehouse team that they need to re-ship that order.
One thing to be aware of... If the order on your selling channel has a shipped or completed status, a store refresh could update the status of the order in ShipStation back to Shipped. So using this method is best when you plan to immediately create a new label for the order to be re-shipped.
