Why per-seat pricing shapes how teams grow

Fourteen people use the system and eight seats are paid for. Nobody planned a workaround; a manager simply declined the fifteenth licence in a tight quarter, and a shared login appeared within a week. The usage data now describes a company that does not exist.

What everyone sees

A pricing unit is treated as a billing mechanism, chosen for fairness and convenience, sitting outside the customer’s behaviour. It does not sit outside. Whatever is metered becomes a cost the customer manages, and managing it means changing the activity the meter was supposed to observe.

What is actually happening

Shapiro and Varian’s analysis of information goods sets out why the pricing unit is a strategic variable rather than an accounting one: with near-zero marginal cost, the chosen unit determines which customer behaviour becomes expensive, and customers reorganise to reduce it. Nagle and Holden’s treatment of pricing strategy makes the same point from the seller’s side, arguing that the metric should track the value the customer receives, because any mismatch between the meter and the value creates an incentive to suppress the metered activity while continuing to consume. Per-seat pricing on collaboration tools is the clearest case. Value rises with the number of participants, and the meter makes each participant a decision.

Why it stays hidden

The distortion hides inside apparently healthy metrics. Seats per account look stable, revenue per account looks stable, and both are stable because growth is being routed around the meter. The absent signal — people using the product through someone else’s login — is invisible by construction.
