Hi Grabriael, the difference you noticed is because PBIVizEdit applies different per‑user rates depending on the plan tier. The “Starter” plan (1–5 users) is priced higher per user, while the “Small” plan (6–99 users) has a lower per‑user rate. If you select the second plan for 10 users, Microsoft will not charge you for 99 licenses; you can specify the exact number of seats you need within that tier. So for 10 users under the “Small” plan, the cost would be 10 × $0.16 per month (after the free first month), or 10 × $1.60 per year if you choose annual billing.
That means, you can customize the seat count within the plan range, and the billing is calculated based on the actual number of users you assign, not the maximum allowed by the tier.
