# quota.threshold_reached

> Usage crossed 80% of a feature's included quantity.

## When this fires

For metered plans, the async usage processor compares each feature's period usage against its included quantity. When usage crosses 80% of the included amount, this fires once for that feature and billing period. Unlimited features never fire it.

If a single burst jumps straight past the included amount, only `quota.exceeded` fires.

Use it to warn the customer they are approaching their limit.
