How do I increase or decrease the price of an invoice before manually sending it to the customer through Shopify’s own invoice function?
Hi!
I made a example item to test this.
I see i can add discount below payment etc, and i can add items, but i cant change the item cost itself + or -.
The reason for us wanting this is that order cost vary depending on what the customer wants for kind of print on the selected items.
Is there a way to change the cost on the items itself before manually sending the invoice?
