We experience the same issue with so many potential users across the community. It adds up to a very expensive exercise quickly and we simply can’t afford to scale up the product too much. An enterprise licence that is based on a different measure rather than per user would make more sense for our use case - as happens for other large systems we implement (we don’t pay per user for our ERP systems). It is strange there is not even a sliding scale for billing that can apply as you increase user numbers.
I have made this suggestion which would assist us somewhat as we have a very large cohort who only need to update items on boards. If you agree you might like to upvote it:
