It’s easy to delete orders from your Shopify admin. You can delete one order at a time, or you can delete multiple orders at once. If you need to delete an order that was placed by a customer, then you can refund the order instead.
When you delete an order, Shopify also deletes any associated products, customers, and transactions. If you need to keep this information, then you can cancel the order instead of deleting it.
