## Why: the goal or problem

Keeping service available costs money even at zero usage, while heavy usage adds cost. One charge must account for both.

## How: work toward a solution

A fictional workspace has three seats and 120 monthly exports. The monthly base is 20, including 100 exports; each extra export costs 0.10. Total: 20 + 20 × 0.10 = 22. Change usage: zero and 100 both cost 20; 101 costs 20.10. Taxes, fees and refunds are omitted.

## What: the concept

Base fee plus overage combines a fixed charge with included usage and a rate for excess units. The base remains payable even with no usage.

Combine with subscription billing.
