Hi @rr20-mailbox-org if your school in Germany signs up as an entity before June (or if they have already signed up) then the standard features available to entities are free. As seen on the pricing page you mentioned: https://myviewboard.com/pricing/
Once your school is signed on as an entity, if your school then wants to have awesome Add on features like Manager Advanced and Clips(in-class learning and hybrid learning subscription packages) then they can contact us to place an order for those extra benefits. Your school can use this contact form to find out more about the Add on Features: https://myviewboard.com/contact/
