Claude and QuickBooks.
Three ways to connect.

By The Experts AI editorial team · Written with AI assistance · Updated October 14, 2026

Short answer: To connect QuickBooks to Claude, open Connectors in Claude, choose QuickBooks and sign in with Intuit; per Intuit it can pull P&L and cash flow reports and create invoices and estimates. To connect QuickBooks to Claude Code, install Intuit's open-source QuickBooks Online MCP server and start with a sandbox company. For dashboards, a CSV export is safest.

There are now three realistic ways to work with QuickBooks data in Claude. They differ a lot in setup effort, power and risk. This guide summarizes what Intuit publishes about each, as of September 24, 2026.

How to connect QuickBooks to Claude Code (MCP server)

Intuit's open-source QuickBooks Online MCP server lets Claude Code read and, if you allow it, change QuickBooks data. Steps from its README, checked October 14, 2026:

1. Register an app on the Intuit Developer Portal, add the redirect URI http://localhost:8000/callback (sandbox only) and copy the development Client ID and Client Secret.
2. Create or open a sandbox company in the developer portal.
3. Clone the repository, run npm install and npm run build, copy .env.example to .env and fill in the client ID and secret, with QUICKBOOKS_ENVIRONMENT=sandbox.
4. Run npm run auth to sign in to the sandbox company; the tokens are saved to .env.
5. Add the server to Claude Code's MCP configuration, pointing to dist/index.js.

{
  "mcpServers": {
    "quickbooks": {
      "command": "node",
      "args": ["/path/to/quickbooks-online-mcp-server/dist/index.js"],
      "env": {
        "QUICKBOOKS_ENVIRONMENT": "sandbox",
        "QUICKBOOKS_DISABLE_WRITE": "true",
        "QUICKBOOKS_DISABLE_UPDATE": "true",
        "QUICKBOOKS_DISABLE_DELETE": "true"
      }
    }
  }
}

With the three DISABLE switches set to true, only read and search tools are available. Production use needs a public HTTPS redirect URI for the one-time sign-in, per the README. Keep the client secret and tokens out of shared folders.

In Claude chat or Claude Cowork, the QuickBooks connector is simpler: in Claude, open Connectors, choose QuickBooks and sign in with Intuit. Per Intuit's help article it can pull P&L and cash flow reports, benchmark against similar businesses, import transactions and create, update, send or delete invoices and estimates (deleting needs your confirmation). See Claude Cowork for bookkeeping.

Which one should you use?

• Just need insights or routine entries in chat: the connector is the easiest.
• Building a custom tool that reads live QuickBooks data: the MCP server, starting in sandbox mode. Its README shows switches such as QUICKBOOKS_DISABLE_WRITE and QUICKBOOKS_DISABLE_DELETE. Consider turning write and delete off while you experiment.
• Building a dashboard or report: a CSV export is often safest. The tool cannot change your books, and you control exactly what data it sees.

Safety notes

• Anything with write access can change real books. Test on a sandbox company.
• Data Claude reads is sent to Anthropic. See our data guide.
• Verify totals against QuickBooks reports before relying on any AI-built view.
