Seat-based pricing
Also: per-seat pricing
Seat-based pricing charges a recurring fee per user licence. It is simple to explain and forecast, and revenue grows as a customer adds people. It works best when value rises with the number of users, and breaks when customers share logins or when value comes from outcomes rather than headcount.
How to read it
Decide how seat additions and removals are billed mid-cycle and whether there is a minimum. Seat counts are a natural expansion and contraction signal, so report their movement in the MRR bridge.
