# Frequently Asked Questions

> Quick answers to common questions about Bizzy accounts, billing, AI, and your data

Short answers to the questions we hear most, with links to the pages that go
deeper.

## Accounts & organizations

<AccordionGroup>
  <Accordion title="What's the difference between an organization and a business?">
    Your **organization** is the workspace — it holds your team, data, and
    billing. A **business** is a commercial identity inside it, with its own
    profile, offerings, and Stripe connection; one organization can run
    several. See [Organizations](/get-started/concepts/organizations) and
    [Businesses](/get-started/concepts/businesses).
  </Accordion>

  <Accordion title="Can I invite my team?">
    Yes — invite members from your organization settings, up to your tier's
    seat limit; paid tiers can purchase additional seats. See [Managing
    Users](/admin-guide/organization/users).
  </Accordion>
</AccordionGroup>

## Billing & credits

<AccordionGroup>
  <Accordion title="How do credits work?">
    One credit equals one cent of overage. Inside your tier's allowance you
    never think about them — they only kick in when usage goes past what's
    included. See [Credits & Billing](/get-started/concepts/credits).
  </Accordion>

  <Accordion title="What happens when I hit a usage limit?">
    You're warned at 90%, overage billing starts at 100% (paid tiers), and
    service pauses at 110% until you top up, upgrade, or the cycle resets.
    The Free tier pauses at 100%. See [Understanding
    Limits](/admin-guide/billing/limits).
  </Accordion>

  <Accordion title="Do credits expire?">
    No. Credit balances carry over between billing periods. See [Credit
    Top-ups](/admin-guide/billing/credits).
  </Accordion>

  <Accordion title="What happens to my data if I downgrade?">
    Nothing is deleted. Anything over the lower tier's caps is paused —
    newest first — and can be re-activated when you're back under the limit.
    See [Understanding Limits](/admin-guide/billing/limits).
  </Accordion>
</AccordionGroup>

## Email, domains & phone numbers

<AccordionGroup>
  <Accordion title="Can I use my existing email address?">
    Yes — connect a Google or Microsoft account via OAuth, or create an
    address on a domain you've verified with Bizzy. See [Connect
    Email](/user-guide/email/connect).
  </Accordion>

  <Accordion title="Can I bring my own domain?">
    Yes. Verify ownership of a domain you already have, or register a new
    one through Bizzy. See [Verify a Domain](/user-guide/domains/verify) and
    [Register a Domain](/user-guide/domains/register).
  </Accordion>

  <Accordion title="How do I get a phone number?">
    Buy one through Bizzy — search by area code and capability, and check
    out in a couple of clicks. If you already have a Telnyx number you can
    attach it directly. See [Buying a
    Number](/user-guide/phone-numbers/buying).
  </Accordion>
</AccordionGroup>

## AI agents & your data

<AccordionGroup>
  <Accordion title="What data can agents see?">
    Agents only see data inside your organization, and only the files you've
    explicitly given them access to — the **Agent access** flag is off by
    default. What agents can *do* is controlled per tool with allow/ask/deny
    permissions. See [Tool Permissions](/user-guide/agents/tool-permissions)
    and [RAG Indexing](/user-guide/files/rag-indexing).
  </Accordion>

  <Accordion title="Is my data used to train AI models?">
    No — your data is not used to train foundation AI models. See the [AI
    disclosure](https://www.bizzyco.ai/ai-disclosure) for the full
    data-handling policy.
  </Accordion>

  <Accordion title="Can I choose which AI model an agent uses?">
    Yes, per agent — every tier can use every available model, and usage is
    billed by the token. See [Agent Models](/user-guide/agents/models).
  </Accordion>

  <Accordion title="Can I review what an agent did?">
    Every chat is recorded as an agent conversation with the full transcript
    — tool calls, results, and approval decisions included. See
    [Transcripts](/user-guide/agent-conversations/transcripts).
  </Accordion>

  <Accordion title="What's the difference between an agent and an automation?">
    Automations are event-triggered rules that run on their own; agents are
    conversational and work with you across multiple turns. See
    [Agents](/get-started/concepts/agents) and
    [Automations](/get-started/concepts/automations).
  </Accordion>
</AccordionGroup>

## Developers

<AccordionGroup>
  <Accordion title="Is there an API?">
    Yes — a REST API at `api.bizzyco.ai/v1` with an OpenAPI spec, plus an
    MCP server so AI tools like Claude and Cursor can work with your data.
    See the [API Reference](/api-reference/introduction) and [MCP
    Server](/mcp-server/introduction).
  </Accordion>

  <Accordion title="How is API auth different from MCP auth?">
    The REST API uses long-lived API keys you create and scope yourself; the
    MCP server uses OAuth with a consent screen where you pick the tool
    categories a client may use. See [API
    Keys](/admin-guide/security/api-keys) and [MCP
    Authentication](/mcp-server/authentication).
