You know, when you split it like that, it almost sounds plausible. So, I looked closely at the PDF:- -"Web development work (Logo and fonts £2,317.50, Favicon £585, E-newsletter £1,080)" Creating a favicon costs a quarter of logo and fonts? That is literally unbelievable. Your reasoning has merits but I think they (the web design company + those who commissioned them) do not merit it.
