This is 2021 and I hoped that there would be an update to this conversation. After setting up shipping charges as an "other charge" item, and making endless attempts with various templates to add it to the footer, it just won't happen. I spent time in a Quickbooks chat and he said this feature is simply not available in Quickbooks.
My only alternative will be to design a decent invoice in Excel or Word, create a invoice in QB simple for accounting purposes that will keep the books straight.
