Why: the goal or problem

Imagine a map-export tool for reports. Some customers make a few images; others make hundreds, so one price hides usage differences.

How: work toward a solution

A fictional map image exporter 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.

Meter units, then calculate the charge.

Usage-based billing

Map image exporter · first three months: 100 / 300 / 600 exports

Month 1 · 0.02 per export

  1. Month 1: 2.00
  2. Month 2: 300 × 0.02 = 6.00
  3. Month 3: 600 × 0.02 = 12.00
Total20.00

100 × 0.02 + 6.00 + 12.00 = 20.00

Fictional amounts. Taxes, fees and refunds omitted.

The customer pays 0.02 per export: 100, 300 and 600 exports cost 2, 6 and 12. Zero exports cost zero here. Payment timing, access limits and seller responsibilities still need contract terms.

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.
