end

#verify(shipment = nil) ⇒ Object

Only verify inventory for completed orders (as orders in frontend checkout have inventory assigned via order.create_proposed_shipment) or when shipment is explicitly passed

In case shipment is passed the stock location should only unstock or restock items if the order is completed. That is so because stock items are always unstocked when the order is completed through shipment.finalize
