how to add freight amount

I need to add the delivery value to the order. How to proceed?
(pt-br) preciso adicionar o valor da entrega ao pedido. Como proceder?

Create a service with reference for example “S001” and call it “delivery charge”, “delivery cost” or however you want to call it. You can input the purchase price (how much you pay for the delivery) and selling price (how much you charge the customer) and then when you create an invoice you can add S0001 and edit the price if needed.
