A mediation engine can assist collecting, aggregating, analyzing, and monitoring data related to customer usage. This data-driven approach can help you make informed decisions about which metrics are most relevant for your pricing model, ensuring that you align your pricing with customer behavior and value. After aggregating and transforming your usage data, you must measure it in a process called metering.
