How to Connect Claude to QuickBooks Desktop (2026)

Short answer: Yes, but not with Intuit's Claude connector, which only supports QuickBooks Online. You need software that reaches the QuickBooks machine and exposes it to Claude, usually an MCP server. Every option is compared below.

QuickBooks Desktop has no cloud API. It accepts qbXML only through an interface on the Windows machine where it runs, so every option puts something on that machine: an MCP server, an ODBC driver, or the Web Connector feeding a hosted API. This guide compares them with prices, then walks through the five-minute setup for the one we build.

Why the official Intuit connector doesn't work for Desktop

Intuit's QuickBooks connector for Claude (listed on claude.com/connectors) signs in with an Intuit account and talks to QuickBooks Online's cloud API. QuickBooks Desktop Pro, Premier, and Enterprise keep the company file on a local disk or file server and expose it only through the QuickBooks SDK's COM interface, using qbXML, on the Windows machine where QuickBooks is installed. There is no Intuit-hosted endpoint for a Desktop file, so no cloud connector, official or third-party, can reach it without something running locally. Every option below is a way of putting that "something" on the machine.

DIY: QuickBooks SDK + your own bridge	Write a COM/qbXML service and an MCP wrapper	Anything you build for	Your time	Teams that already maintain a QuickBooks integration

Two things to notice. First, many tools that come up for "QuickBooks" and "Claude" (Intuit's connector, Windsor.ai and many directory MCP servers) use QuickBooks Online's cloud API, which a Desktop company file doesn't have. Check that a tool names QuickBooks Desktop before you try it. Second, the Desktop options differ in three ways that matter: whether they depend on the Web Connector and its polling schedule, whether you pay once or every month, and which AI clients they work with. Conductor's MCP server and Apideck's connector both run through the QuickBooks Web Connector, which checks in on a schedule (polling). LedgerCrossing sends requests straight to QuickBooks instead: no Web Connector, no polling schedule, a one-time purchase per machine, and on your office network nothing leaves it. It works with any MCP client (claude.ai and ChatGPT over LedgerCrossing Remote).

Compatibility note. LedgerCrossing works with anything that can make a web request. Off-the-shelf apps that sync through the Web Connector today (ServiceTitan, JobNimbus, Connex, and similar) are controlled by their vendors, and LedgerCrossing is not a drop-in replacement underneath them. If you or your developer control the integration, switching is straightforward: send the same qbXML you send today as an HTTP POST.

Connect Claude to QuickBooks Desktop with LedgerCrossing

The full quickstart with every client's config is at /docs/mcp. The short version:

Before you start

LedgerCrossing installed and activated on the QuickBooks machine (buy it here, $299 one-time).
QuickBooks Desktop running with the company file open (or auto-openable).
By default each request names its company file (Settings > QuickBooks > The caller names the file in each request). Ask your agent to use a file by name, or choose Always use this company file.

Claude Desktop on the QuickBooks computer (about 5 minutes)

Download ledgercrossing.mcpb. If your browser warns about the download, choose Keep.
In Claude Desktop, open Settings > Extensions > Advanced settings.
Under Extension Developer, click Install Extension… and choose the .mcpb file. Do not double-click the file; Windows has no file association for it.
Leave the three settings at their defaults and enable the extension. On the same machine the bundle reads the API key from LedgerCrossing's own config, so there is nothing to copy.
Ask Claude: "Which customers are 60+ days overdue?"

Claude Desktop on another computer in your office

Same bundle. On the QuickBooks machine, turn on Allow under LedgerCrossing Settings > Allowed Connections > Local network, then copy the MCP Server address and API key from that tab. On your workstation, install the LedgerCrossing .mcpb extension the same way, then enter that address and key in the extension's settings. The call goes across your LAN; nothing leaves the office and there is no subscription.

Claude Code, Cursor, VS Code

One command for Claude Code (replace YOUR_KEY with the API key from Settings > Allowed Connections):

claude mcp add --transport http quickbooks http://localhost:8284/mcp --header "X-Api-Key: YOUR_KEY"

Cursor and VS Code use the same URL and header in their mcp.json; configs are in the quickstart.

claude.ai or ChatGPT (outside the office)

The web apps can't send an API key, so a QuickBooks connection needs an HTTPS endpoint with sign-in. The only other choice, no authentication at all, isn't acceptable for your books. LedgerCrossing Remote ($39/mo) provides that, with per-person usernames and passwords the owner can make read-only or scope to specific company files. Setup: /docs/connect. Everything on the same machine or network above is free; Remote charges for hosted reachability, not for MCP.

What Claude can do once connected

LedgerCrossing's MCP server exposes six tools: list the 240 qbXML operations, get one operation's full field rules, validate a request locally, run it against QuickBooks, explain a QuickBooks status code, and check status. In practice that means Claude can answer questions like overdue receivables, items below reorder point, or this month's sales by rep, and can create or edit records: invoices, payments, customers, bills. The catalog is built from Intuit's own qbXML reference (field names, types, order, lengths and version gates), so Claude looks up operations on demand instead of being handed a giant prompt. To have Claude enter a bank or card statement, see How to import bank and credit card transactions into QuickBooks Desktop.

What a LedgerCrossing customer uses it for, in their words:

"I use it … when I need it to build out any reports. I just tell Claude to check in with QuickBooks and give me an Excel sheet of it or, when entering any invoices, I upload it to Claude and tell it to enter it into QuickBooks. When I wanted to reconcile a card, I just upload the statement to Claude, tell it to enter it into QuickBooks, and follow the previous rules of previous entries that I did manually so it knows what to do and you don't have to walk through all steps."

Before you let an agent write to your books

It is not read-only. The agent has the same capability as the REST API, including creating and editing transactions. Connect agents you trust to company files you mean to let them touch. QuickBooks' Audit Trail records every posted transaction.
Open-ended list queries refused by default. A list or transaction query with no limit is stopped before it reaches QuickBooks; the AI has to set one.
QuickBooks must be running with the company file open. That is a QuickBooks Desktop constraint and the reason cloud-only servers can't do this job.

Frequently asked questions

Can Claude connect to QuickBooks Desktop? Yes, through a bridge app on the QuickBooks machine. Intuit's official Claude connector supports QuickBooks Online only. LedgerCrossing runs on the QuickBooks Desktop machine and includes an MCP server that Claude Desktop, Claude Code, Cursor, and VS Code connect to.

Does the Intuit QuickBooks connector for Claude work with QuickBooks Desktop? No. As of October 2026 it connects QuickBooks Online accounts. Desktop company files are local and need software running on that machine.

Do Windsor.ai or other Claude connectors work with QuickBooks Desktop? Most connect through QuickBooks Online's cloud API, which a Desktop company file doesn't have. Windsor.ai's guide, for example, signs in with a QuickBooks Online account. Check that a connector names QuickBooks Desktop (Pro, Premier or Enterprise) before you try it.

Can I use ChatGPT with QuickBooks Desktop? Yes, over LedgerCrossing Remote ($39/mo), which gives ChatGPT a secure address with per-person sign-in. ChatGPT can't reach a computer in your office directly. Step by step: How to connect ChatGPT to QuickBooks Desktop.

Is the QuickBooks Desktop MCP server free? It is included in LedgerCrossing, a $299 one-time purchase per machine (limited-time price; rises to $349). There is no separate MCP tier, preview, or subscription.

Can I use claude.ai, the web app, with QuickBooks Desktop? Yes, over LedgerCrossing Remote ($39/mo), which gives claude.ai and ChatGPT an HTTPS endpoint with per-person sign-in. On the same machine or office network, Claude Desktop connects free.

Is it read-only? Not on the QuickBooks computer or the office network: there the agent can create invoices, payments, and edits with the same capability as the REST API. Over LedgerCrossing Remote, each person starts read-only until the owner allows writes. Open-ended list and transaction queries are refused by default, and QuickBooks' Audit Trail records every posted transaction.

Is it safe to connect Claude to QuickBooks Desktop? LedgerCrossing runs on your QuickBooks computer, is code-signed by EFFIQUEST, LLC, and sends no QuickBooks data to us; the data Claude asks for goes to Anthropic under your Claude account. Access from outside the office is off until you set it up, LedgerCrossing Remote starts every person read-only, and every qbXML request is written to an audit log on the machine. The details for IT: Security and IT review.

Which QuickBooks Desktop versions work? Pro, Premier, and Enterprise, 2019 and later, on Windows 10 or 11, and Windows Server 2016–2025. Older versions back to 2014 use the same Intuit connection and should work, though we haven't tested them; the 30-day guarantee covers you.

Does this replace the Web Connector for my other apps? Not for vendor-controlled apps. LedgerCrossing works with anything that can make a web request, so integrations you or your developer control can switch by sending qbXML as an HTTP POST. See Web Connector alternatives.
