How to use AccountingQB
There are four ways to use AccountingQB with your QuickBooks — they all run the same 138 tools and the same free 14-day trial (no credit card). Pick whichever fits how you like to work.
New here? Start your free trial first — every option signs in to the same account.
Add it as a connector in Claude
Best for you if: you already use Claude (web, desktop, or mobile) and want nothing to install.
https://mcp.accountingqb.com/mcpSteps:
- In Claude, open Settings → Connectors
- Click Add custom connector
- Paste the URL above and click Add
- Click Connect and sign in with your AccountingQB account
- Approve access for your license — that's it
Nothing to download and no API key — you use AccountingQB with your existing Claude subscription. Your books pass through our zero-retention connector and are never stored.
Download the desktop app (macOS / Windows)
Best for you if: you want a dedicated local app that runs entirely on your own machine.
- Download and install the app for your platform (buttons below).
- Open the app and activate — enter the license key we email you, or start a free trial right in the app.
- Connect your QuickBooks company when prompted.
- Add your own Anthropic API key in the app to chat with your books.
Fully local — your books never leave your machine. The desktop app uses your own Anthropic API key for chat (you add it once in the app); the other options use your Claude subscription instead.
Install the Claude Desktop extension (.mcpb)
Best for you if: you use Claude Desktop and want a one-file local install.
- Install Claude Desktop if you don't have it.
- Add the AccountingQB extension and enter your license key.
- Connect your QuickBooks company when prompted.
- Full step-by-step with the config details: open the setup guide.
Runs locally through Claude Desktop — your books never touch our servers.
Add the Cowork plugin
Best for you if: you work in Cowork and want AccountingQB available there.
- Download the plugin: accountingqb.plugin.
- In Cowork, add the plugin from the downloaded file.
- Sign in with your AccountingQB account and approve access for your license.
The Cowork plugin connects through the same hosted connector — no separate setup.
