Community vs. Premium Pricing & Features

Hi, I'm a system admin looking at several LMS platforms both for online learning and for collaboration features. I want to host a truly FOSS package on my server, since I'm already paying for my server and online software can become expensive over time. Sometimes the freemium features can be an obstacle to adopting a package. I'm not completely opposed to paying for the cloud features, but what I'm bothered by is at what point the pricing of the fully hosted version versus hosting myself & adding in the collaboration and video conferencing capabilities cross paths. I am not sure I'm calculating the pricing correctly, but it's looking like hosting myself and adding in the collaboration and video conferencing capabilities may be more expensive than hosting with the Business package. Since I'd be running everything else on my own server, I'm not sure this makes sense, so I want to check my numbers. Using these pages: https://www.opigno.org/en/features/opigno-collaborative-solutions - for the community package with cloud add-on feature pricing https://www.opigno.org/en/professional-services/cloud-hosting - for the fully hosted version pricing Prices are in USD 50 users with 5 video conferencing hosts: $41.50/month with the community version or $40.20 with the fully hosted Business package 100 users with 5 video conferencing hosts: $53/month with the community version or $46.70 with the fully hosted Business package 1000 users with 20 video conferencing hosts: $170/month with the community version or $163.70 with the fully hosted Business package These assume no extra disk space is needed. I understand that +1 user drops the price per person slightly on the community version. However the price savings hosting everything else on my own seems insignificant compared to having a fully hosted package. Are my numbers correct? I suppose I could personally initiate and schedule all meetings as the administrator to save money. However, I don't want that to be my "job" if we get to the point of having many people using the platform. Do all of my students need to be counted in the "users"? If I am able to have a group of users with collaboration privileges versus the entire student body, that could significantly change the numbers. If so, can privileged "collaborators" invite students/unprivileged users to view or comment on collaborations? I don't expect the entire student body to use the collaboration features, so the last question is just out of curiosity. Basically, I'll have public-facing courses with students purchasing access to courses from the web and I'll want to collaborate with some workgroups, instructors and colleagues separately from the courses. I could quickly lose all my profits for "lifetime access" students to monthly fees for the collaboration platform I use with my colleagues. Thank you, Criss
