You seem to have an implicit assumption that there will necessarily be some amount of "support/onboarding/custom feature development" needed.

For the vast majority of your users, I would expect the amount of installation-engineering required to be zero. For every big business on an Enterprise plan of a SaaS like e.g. Cloudflare, there are 10 or 20 accounts for customers just as big(!) who are on their Business plan — which is basically the same feature-set, but without any of the high-touch custom stuff. Because they don't need any of it, in order to get all the value they need from the SaaS.

In other words, it feels like you have an Enterprise plan, but no Business plan. It's pretty easy to construct one — just assume any high-touch stuff doesn't happen. What's the base cost, per user?
