Customer pays for what they use. Growth tracks customer adoption directly.
Customer pays a fixed contract. Growth requires explicit renewal upgrades.
Consumption tends to produce higher headline NRR (>120-150%) because customers naturally consume more as their business grows - no salesperson needed for expansion. Subscription tends to produce more predictable NRR (~110%) because expansion requires proactive upsell motions. Hybrid (e.g., Datadog) often gets best of both.
