Usage-based pricing turns a software bug into a billing event. A loop that retries forever can be expensive by morning.
Basics
- Tag spend by team, project and feature.
- Set budgets and alerts at several thresholds, with named responders.
- Apply per-key and per-user limits.
- Review the top cost drivers monthly.
- Track cost per completed task, not just total spend.
Test the alerts. An alarm nobody receives is not a control.
