We have a product that heavily relies on open source licenses like Apache 2.0, GPL etc.
Our product is a service that we host inhouse and our customers use (like Basecamp), like a Saas, so nobody would ever get the source code.
I know I have to include license notice of the used framework, but where exactly do include this notice? Do I put a special page IN the product? Should I include it in sales agreements? Or maybe just on a section on our product website?
