Order Status must be Void or Open
If an order has been placed, it must be set to Void to be deleted.
If an order has not yet been placed, it is an Open order and can be deleted at any time.
Inside the order, click "More" in the upper right corner and select "Delete Order." If the "Delete" option does not appear, double check that the Order Status is set to either Open or Void.
Delete Multiple Orders
Select multiple Open or Void orders from the Orders page and select "Delete" from the status dropdown in the toolbar.
