Hi guys, I read Ulrich's book as I have an enterprise focused collaboration solution (AI) being developed. I think it makes sense for us to price for usage, infra and some services. I have a good contract lawyer who can draft pretty much any legal agreement but a question lingers: how do you guys do it operationally? (what tech stack do you use from "quote to cash" to implement complex pricing structure? Any stack that would scale from startup to more mature state?). On a separate but related topic : what license server/engine would you recommend for an AWS BYOL approach? Thank you!
