# Plans & billing

> Bookbag's plans — Free, Starter, Growth, Scale, and Enterprise — and how the credits model works: billing is per workspace (members share the workspace's plan and credits), every plan has a finite monthly allotment, plus usage tracking and auto-recharge.

Bookbag billing is built around **credits**. Each AI reply consumes credits, and every plan includes a monthly credit allotment. Plans also set your limits — agents, data sources, team seats — and which channels and features you can use.

> **INFO:** See the credits model in depth in [Credits & usage](/docs/agents/credits), and the current prices on the [pricing page](/pricing).

## Billing is per workspace

The subscription, plan, and credit balance belong to the **workspace** — not to you personally. When you invite teammates to a workspace, they work under **that workspace's plan**: they use its features and draw from its **shared credit balance**, and the workspace **owner** is the one who pays. Collaborators don't need their own paid plan to help out.

> **INFO:** Your account can own one workspace and be a member of others. The plan and credits you see in the app always belong to the **workspace you're currently in** — switch workspaces (top-left) and the plan, features, and credit balance switch with it.

## The plans

Bookbag offers five plans, from a free tier for trying things out to Enterprise for high-volume teams. Every plan has a defined monthly credit allotment — **no plan is unlimited**.

| Plan | Monthly credits | Agents | Seats | Highlights |
| --- | --- | --- | --- | --- |
| Free | 50 | 1 | 1 | Website widget + API. Try Bookbag end to end at no cost. |
| Starter | 600 | 2 | 1 | Adds Slack & email channels, store integrations, and removes Bookbag branding. |
| Growth | 5,000 | 5 | 5 | Adds voice, help desk, human handoff, skills, WhatsApp/Messenger/Instagram, analytics, scheduled retraining, and a custom domain. |
| Scale | 15,000 | 20 | 15 | All channels, advanced analytics, priority routing, white-label, and SSO. |
| Enterprise | Custom (from 50,000) | Custom | Custom | Custom volume, all features, HIPAA, audit logs, and custom roles. Contact sales. |

> **TIP:** Higher plans raise the per-agent **data source** limits too (from 10 sources on Free up to thousands on Scale, and a custom amount on Enterprise).

## How credits work

A credit is the unit of usage. Each AI reply costs credits according to the model's configured cost, so cheaper, faster models stretch your allotment further. Your plan refreshes a **monthly allotment** of credits.

- **Monthly allotment** — the credits your plan includes each billing period. Shared across everyone in the workspace.
- **Credits used (30d)** — how much the workspace has consumed in the trailing 30 days, shown in the billing summary.
- **Credits remaining** — what's left in the workspace's current balance. The Credits widget in the sidebar shows this at a glance.

> **WARNING:** There is **no unlimited plan**. Every tier — Free through Enterprise — has a finite monthly credit balance, and once it runs out the agents stop replying until the next refresh, a top-up, or an upgrade. Enterprise volumes are custom (starting at 50,000 credits/month). Set **auto-recharge** if you never want to run dry.

See [Credits & usage](/docs/agents/credits) for exactly what consumes credits and how per-model costs are set.

## Auto-recharge

To avoid running out mid-month, you can enable **auto-recharge**: when your balance drops below a threshold you set, Bookbag automatically tops it up by the amount you choose. Configure the threshold and top-up amount in billing.

> **TIP:** Set the threshold high enough that a busy day won't interrupt your agents before the recharge clears.

## Upgrading and checkout

1. **Open billing** — Go to your workspace billing page to see your current plan, usage, and the plan catalog.
2. **Choose a plan** — Pick the plan that fits your volume, seats, and channel needs.
3. **Check out** — Checkout is handled securely through Stripe; your plan and credit allotment update once payment completes.

> **INFO:** Billing actions (checkout, auto-recharge) require an **Admin** or **Owner** role. The self-hosted open-source build runs with unlimited local entitlements and no payment.
