Thank you for reaching out and I’d be happy to lend a hand with this!
Looking at the screenshot, it looks like you want to add the shipping title to the payment details section of the invoice. Since there is a “shipping” field already, then you can add the title of the shipping title and/or shipping price using the following variables:
If so, then you can try copying the snippets of coding from my example (below). However, it’s important that you double-check the placement using the surrounding variables on your template, as the actual line numbers may be different between our templates.
If you need further assistance with modifying your invoice, then this is also something that our Theme Support team can help you with. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit the Shopify Help Center and log in to your account to create a support request.
I’d love to know if my example can help you add the shipping title to your invoice. Let me know!
