## Why: the goal or problem

Light and heavy customers consume very different resources. Charging both identically may not reflect value or operating cost.

## How: work toward a solution

A fictional export tool charges 0.02 per export. Across months with 100, 300 and 600 exports, charges are 2, 6 and 12: total 20. Change month-one usage or add one export to update its charge and the total. Zero usage costs zero here. Taxes, fees and refunds are omitted.

## What: the concept

Usage-based billing calculates charges from measured consumption. Define the billable unit and collection schedule separately; usage can be billed within a subscription.

Explain metering and budget variability; compare prepaid credits.
