"The different vendors pay Clever, and Clever offers the service to schools for free." This is the sole reason this will never work. I've been in education and developing education software for well over a decade now, and no one I know (vendors) want a single provider monopolizing the game in this way. In the UK at least, we (vendors) are struggling to remove the strangle hold of the monopolizing few; namely Capita and Serco. But all that said, I do wish you the best and hope you find some solution that works. Interoperability of school data/systems is a giant PITA, which I've spent way to much of my life on.
