# Credits & Billing

Supademo agent credits are a usage-based add-on on all paid plans: 1,500 free credits per workspace, packages from $99, and credits that never expire.

AI Demo Agents run on **credits** — a usage-based add-on available on all paid Supademo plans. Every workspace starts with **1,500 free credits** (roughly 75 agent calls), usage costs 1 credit per agent reply plus 1 credit per 15 seconds of voice audio, and paid packages start at $99 with credits that **never expire**. This page covers how credits are consumed, package pricing, session limits, and how to keep costs predictable.

## How Credits Are Consumed

| Usage Type        | Cost                                                                |
| ----------------- | ------------------------------------------------------------------- |
| **Agent replies** | 1 credit per AI-generated agent reply (text or voice).              |
| **Voice audio**   | 1 credit per 15 seconds of voice audio, on top of the reply credit. |

A typical **15-minute voice call consumes about 20 credits**, so the free 1,500-credit allowance covers roughly 75 calls. Text-only conversations cost less than voice conversations of the same length, since they skip the voice-audio metering.

Credits are tracked at the **workspace level**, and every workspace gets its own free 1,500-credit allowance. Enterprise plans share a credit balance across all workspaces in the organization. Credits never expire — anything you buy stays available until it's used.

### Grace Buffer

A grace buffer of **2,000 credits** prevents abrupt cutoffs mid-conversation. If your balance dips slightly below zero, active sessions continue until completion. New conversations are blocked once the buffer is exceeded.

## Credit Packages and Pricing

Credit packages can be purchased self-serve from your workspace on any paid plan:

| Package    | Credits              | Price per credit | Approx. 15-min voice calls |
| ---------- | -------------------- | ---------------- | -------------------------- |
| Free       | 1,500                | $0 (included)    | \~75                       |
| **$99**    | 1,400                | \~$0.071         | \~70                       |
| **$299**   | 5,500                | \~$0.054         | \~275                      |
| **$500**   | 12,500               | $0.040           | \~625                      |
| **Custom** | Sized to your volume | Varies           | From $99 up to $5,000      |

Larger packages carry a lower per-credit price, bottoming out at **$0.040 per credit** on the $500 package. Custom packages run from **$99 to $5,000** — for high-volume deployments and volume discounts, [book a scoping call](https://cal.com/team/supademo/ai-demo-agents). \[VERIFY: whether the legacy "$0.51-0.70 per \~15-minute call" volume pricing floor still applies to custom deals]

### Auto-Recharge

Turn on optional **auto-recharge** to top up automatically whenever your balance falls below **500 credits**. This keeps a busy agent from going dark mid-campaign without anyone watching the balance. Leave it off if you'd rather approve every purchase manually — the 2,000-credit grace buffer still protects in-flight conversations either way.

## Session Limits

| Limit                      | Value                                      |
| -------------------------- | ------------------------------------------ |
| **Session limit**          | 20 minutes                                 |
| **Inactivity timeout**     | 10 minutes of no activity.                 |
| **Expiry warning**         | Shown 2 minutes before the session ends.   |
| **Daily conversation cap** | Configurable, 1 — 10,000 (default: 5,000). |

The daily conversation cap is set in Security settings. Active sessions are never interrupted when the cap is reached — only new conversations are blocked. Session limits are your hard ceiling on per-conversation cost: at roughly 20 credits per full 15-minute voice call, even a maximum-length session stays in a predictable credit range.

## Managing Costs

* **Set a daily cap** — Use the Max conversations per day setting in Security to prevent runaway usage.
* **Monitor per-session credit usage** — The Sessions table shows credits consumed by each conversation. See [Agent Analytics](https://docs.supademo.com/ai-demo-agent/agent-analytics).
* **Track volume trends** — Use the Insights dashboard to understand conversation volume over time and spot unexpected spikes.
* **Optimize your knowledge base** — Better content means fewer back-and-forth messages, shorter conversations, and lower credit consumption per session.
* **Restrict embed domains** — Limit where your agent can be embedded to prevent unauthorized usage on third-party sites.
* **Use auto-recharge deliberately** — Enable it for always-on agents on high-traffic pages; skip it for internal or experimental agents.
