Once education demonstrably drives adoption and retention, stop treating it as free garnish. Bundle certification seats into enterprise tiers. Make advanced credentials part of the partner requirements — Stage 03 will need this. Offer paid recertification where CEU or compliance value justifies it.
Whether education is a paid line or a strategic subsidy is a per-company decision; making that decision deliberately, with the retention data in front of you, is the play.
The decision, not the answer
There is no universal right price for education. There is a universal wrong posture: never having decided.
