I have been able to change some of the layout for the HTML invoice by editing admin_invoice_html.html & user_invoice_html.html
but I am unable to find a similar file for PDF version of invoice
Which file(s) should I edit?
We want to add EFT transfer details to the bottom of the invoices and want it to automatically set a Payment Ref# to the Invoice Number in case our users want to pay by bank deposit rather than credit card
