Where will my surcharges be displayed?
Fooman Surcharge has fully integrated Magento 2 display.
Remember to give your surcharge a descriptive label, so your customer can easily identify what the additional charge is for and the value they are getting out of this charge. Surcharges are not displayed on the product page. If needed, you should include information about any surcharges in your web copy.
Surcharges will be shown the following places:
Print Order page - Magento 2 Order, Invoice and Credit Memo Totals
My Account Order View page
Magento 2 customer sales emails
Pdfs generated by Magento 2
Fooman Surcharge is also compatible out-of-the-box with Fooman Pdf Customiser PDF's.
