- Seats — the number of Cara users assigned in your agency (Manage subscription).
- Usage — three metered units that reflect how much work Cara is actually doing.
Metered units
Every Cara invoice reports three usage counters:Metered units are additive to your seat plan, not a replacement. Seats gate who can log in and use Cara; usage tracks how much they use her.
Where to see current usage
Navigate to Settings → Subscription → Usage to see:- Month-to-date counters for each metered unit
- Rolling 12-month trend for each meter
- Included allotment vs billable overage for your plan
VOICE_MINUTE, and workspace volume aligns with PLATFORM_UNIT.
Alerts
You can configure alerts on any of the three meters:- Threshold alert — email your admin team when a meter crosses a percentage of the included allotment.
- Anomaly alert — email when the daily rate on a meter is materially higher than the trailing average.
Reducing usage
If a meter is running higher than expected, the analytics dashboards show the underlying drivers:PLATFORM_UNIThigh — check the preset mix in the Workspaces dashboard. High-volume custom presets are the most common cause; consider tightening the prompt so Cara does less redundant work.VOICE_MINUTEhigh — check the call volume trend and disconnection breakdown. Long, transfer-heavy calls are the most common cause; adjust Voice AI transfer settings or business hours.KB_PAGEhigh — check the Knowledge Base for large or frequently re-uploaded documents. Delete obsolete versions and prefer folders over duplicates.
