Connect QuickBooks to Claude

Automatically sync your QuickBooks Online data to Claude using the Windsor.ai connector.

Intuit’s own Claude connector pulls reports and creates invoices inside QuickBooks, in the US. Windsor.ai gives Claude the general ledger lines, profit and loss, balance sheet and receivables behind those reports, in any region, and puts them next to Google Ads, GA4 and Meta Ads so you can see marketing spend against real revenue.

Forget CSVs. Stop copy/paste. Connect data in minutes. No code required.

Which one do I need?

All four methods below get QuickBooks Online data in front of Claude. They differ in how deep Claude can go, whether it can write back, where you can use them, and what else Claude can see alongside your books.

“Best for” leads so you can jump straight to the row that matches your situation.

	Intuit’s QuickBooks connector	Windsor.ai	Report export	QuickBooks API / custom MCP
Best for	Standard reports, benchmarks and creating invoices from chat	Transaction-level analysis, multi-year history, and books next to marketing data	One question about a fixed period	Bespoke workflows the others don’t cover
Depth	Summary reports (P&L, cash flow, benchmarks)	General ledger lines, P&L, balance sheet, invoices, bills, aged receivables	Whatever the report contains	Whatever you build
Write access	Yes: invoices, estimates, payment links, transaction import	Read-only	No	Yes, if you build it
Cross-channel analysis	No	Yes, 350+ sources	Only what you upload	Only if you build it
Where it works	US customers only, per Intuit	Any region	Any	Any
Setup effort	Low (native, Intuit login)	Low (no code)	None, but repeated every report	High (developer task)

The custom MCP route is last on purpose. It is the heaviest option, a developer task, so it belongs at the end as the fallback for cases the other three do not cover.

Method 1

Intuit's official QuickBooks connector for Claude

Intuit lists a QuickBooks connector in Claude’s directory and expanded it in July 2026 with invoicing and other actions. It covers QuickBooks Online on every plan, Intuit Enterprise Suite and Accountant Suite. Claude can pull profit and loss and cash flow reports, benchmark your business against industry peers, import transactions from a CSV, PDF or image, and create, update and send invoices, estimates and payment links. Full details in Intuit’s help article, updated August 2026.

Setup steps

Open Connectors in Claude

In Claude on the web or desktop, open Connectors from the left navigation and click Browse connectors.

Find QuickBooks and connect

Search for QuickBooks (Intuit), click Connect, and sign in with the Intuit account that owns the QuickBooks Online subscription.

Pick the company

Authorize the company file you want Claude to use. Destructive actions such as deleting an invoice ask for your confirmation first.

Turn it on in chat

In a conversation, enable QuickBooks under Search and tools and ask for a report, a benchmark or an invoice.

What it can do

Pull profit and loss and cash flow reports, and benchmark your numbers against industry peers
Create, update, send, duplicate and delete invoices and estimates, add customers and products, create payment links
Import transactions from CSV, PDF, image or pasted data into a QuickBooks account
Work without a QuickBooks login for basic P&L or cash flow summaries from data you paste in

What it can't do

Work outside the US, Intuit says the connector is available to US customers only for now
Go below the report level, reviewers on Reddit and LinkedIn note it returns summaries rather than transaction lines to drill into
See anything outside QuickBooks, no ad spend, no web analytics, no CRM
Cover QuickBooks Desktop, which Intuit's documentation does not mention

Example prompts

Show my profit and loss for last quarter and compare it with the same quarter last year.

How does my gross margin compare with businesses like mine?

Create an invoice for Acme Ltd for 40 hours of consulting at our standard rate and send it.

Method 2

Windsor.ai for transaction-level analysis and marketing ROI

Windsor.ai’s connector gives Claude the rows behind the reports. The most requested QuickBooks data through Claude is the general ledger line by line, then profit and loss, account balances, invoices, bills, the balance sheet and aged receivables, and teams pull a full year or two of history as often as the last 30 days. Among teams that query QuickBooks through Windsor’s Claude connector, 3 in 10 also query Google Ads in the same period and about 1 in 4 GA4 and Meta Ads, which is how marketing spend gets measured against booked revenue. The connector works in any region and is read-only.

Setup takes a few minutes

Connect QuickBooks to Windsor

Go to onboard.windsor.ai/app/quickbooks and authorize your QuickBooks Online company. Windsor pulls the general ledger, accounts, invoices, bills, purchases, customers, vendors and the standard reports.

Add the Windsor.ai connector to Claude

In Claude, open Customize, then Connectors, search for Windsor and click Add. Sign in to your Windsor.ai account when prompted, and the connector appears in your Connectors list. You can also open the Windsor.ai listing in the Claude directory (https://claude.ai/directory/360c0c31-4bb6-42ca-8e50-5da0a100a68e) and click Connect.

Ask questions

Start a new chat and ask about cash, margins, receivables or expenses in plain language, for any period your QuickBooks history covers.

No code, API keys or custom pipelines required. Runs on Windsor MCP for Claude. Screenshots for each step are in the setup guide.

Queried live against the QuickBooks Online API, so there is no fixed sync schedule. Full list of 660+ fields in the QuickBooks field reference.

Example prompts

General ledger review

List general ledger lines for the last 30 days with generalledger__item__tx_date, generalledger__item__account_name, generalledger__item__txn_type, generalledger__item__memo, generalledger__item__debt_amt and generalledger__item__credit_amt. Flag duplicate amounts to the same vendor within 5 days and any uncategorized expense over 500.

Group general ledger lines for this year by generalledger__item__account_name and month. Which expense accounts are growing fastest?

Profit and loss

Show profitandloss__income, profitandloss__cogs, profitandloss__grossprofit, profitandloss__expenses and profitandloss__netincome by month for the last 12 months. Where did gross margin move, and which months ran a loss?

Compare year to date profitandloss__netincome with the same period last year and explain the difference by income and expense line.

Cash and balances

Show accounts__name, accounts__accounttype and accounts__currentbalance for all active bank and credit card accounts. Then compare average monthly expenses over the last 6 months with cash on hand and estimate runway in months.

Receivables and payables

List open invoices with invoices__customerref, invoices__docnumber, invoices__totalamt, invoices__balance and invoices__duedate, and show the agedreceivables buckets. Which customers are consistently late, and who should we chase first?

List bills due in the next 30 days with bills__vendorref, bills__totalamt, bills__balance and bills__duedate, and compare the total with current cash.

Cross-channel

Put Google Ads and Meta Ads spend by month next to profitandloss__income for the last 12 months. What is revenue per dollar of ad spend, and how has it moved?

Compare GA4 purchases and revenue with QuickBooks invoices__totalamt by month for this year. Where do the two disagree, and by how much?

Cross-channel questions to ask next

Revenue per dollar of Google Ads and Meta Ads spend, on booked revenue rather than platform-reported conversions
Whether GA4 revenue and QuickBooks invoices reconcile month by month
Which customers from your CRM pay late, and what that does to cash
Whether Shopify orders and QuickBooks income match after refunds and fees

Method 3

Report export from QuickBooks

The zero-setup route: run a report in QuickBooks Online, export it as Excel or CSV, and upload it into a Claude conversation. For a single question about a fixed period, this works on any Claude plan and in any region.

What it can do

One-off analysis with no account connection or new tools
Works on any Claude plan, including free
Good enough for a fixed-period question you will not repeat

What it can't do

Stay current, the export is a snapshot that goes stale the moment you download it
Avoid repeat work, every follow-up period means another export and upload
Combine the ledger, invoices, bills and reports in one file, each is a separate export
See other channels unless you export and upload each of them too

How: in QuickBooks Online, open Reports, run the report and date range you need, export to Excel or CSV, then drag the file into Claude and ask your question.

Method 4

QuickBooks API with a custom MCP server

If none of the above cover your workflow (an internal approval step, a report shape neither connector produces, a custom object), you can build your own MCP server against the QuickBooks Online API and expose it to Claude. Intuit also documents an MCP server for developers.

This is the heaviest route here: you handle the Intuit developer app, OAuth tokens, rate limits and API changes yourself rather than doing a no-code setup.

What it can do

Whatever you build, full flexibility over endpoints, objects and actions
Cover workflows that neither the official connector nor Windsor.ai support

What it can't do

Work without developer effort, there is no no-code path here
Avoid ongoing maintenance, tokens and API versions rotate

Reach for this only when Methods 1 to 3 do not cover your case. It carries build and maintenance cost that the other three do not.

Conclusions: which method wins for your use case

Your situation	Recommended	Why
“I want to explain a number down to the transactions behind it”	Windsor.ai	General ledger lines, invoices and bills, not only report totals
“I want marketing spend measured against revenue in the books”	Windsor.ai	Only method here that spans 350+ sources beyond QuickBooks
“I am outside the US”	Windsor.ai	Intuit’s connector is US only for now
“I want to create invoices and estimates from chat”	Intuit’s connector	Only no-code method here with write access
“I just want a P&L, cash flow or benchmark in chat”	Intuit’s connector	Native and built for those reports
“I have one quick question about last month’s numbers”	Report export	Fastest path for a true one-off, no account connection needed
“None of the above cover what I need, and I have dev resources”	Custom MCP	Full flexibility, at the cost of build and maintenance effort

FAQs

What are the main ways to connect QuickBooks to Claude?

Four: Intuit’s official QuickBooks connector in Claude’s directory (reports, benchmarks, invoicing, US only), Windsor.ai (no code, read-only, general ledger and report data next to 350+ other sources, any region), a report export for a one-off question, and a custom MCP server on the QuickBooks API for developers. The comparison above shows which fits your case.

How is Windsor.ai different from Intuit's QuickBooks connector for Claude?

Depth, direction and reach. Intuit’s connector works at the report level and can write: profit and loss, cash flow, benchmarks, plus creating invoices, estimates and payment links. Windsor.ai is read-only and goes to the general ledger line, with invoices, bills, aged receivables and the balance sheet, across as many years as your QuickBooks history holds, and it puts those numbers next to Google Ads, GA4, Meta Ads and your CRM. Intuit’s connector is limited to US customers; Windsor works anywhere. Many teams use both.

Does this work with QuickBooks Desktop?

No. Windsor.ai’s connector reads QuickBooks Online, and Intuit’s documentation for its Claude connector does not mention QuickBooks Desktop either. Desktop users can export reports to Excel and upload them to Claude, or migrate to QuickBooks Online.

Can I use this outside the US?

With Windsor.ai, yes, in any region where QuickBooks Online is available. Intuit states that its own Claude connector is currently available to US customers only, with other regions to follow.

Can Claude create invoices or record transactions in QuickBooks?

Through Intuit’s connector, yes: it can create, update, send and delete invoices and estimates, add customers and products, create payment links and import transactions, with confirmation before destructive actions. Through Windsor.ai, no: the connector is read-only, built for analysis rather than bookkeeping. The Available actions block above is pulled live from the Windsor.ai API and stays empty for QuickBooks.

Is my financial data secure when connecting QuickBooks to Claude?

Windsor.ai connects through QuickBooks Online’s official API with OAuth, is SOC 2 compliant, reads only what you authorize, and fetches data only when you ask Claude a question. Intuit states that QuickBooks data accessed through its connector is not used to train Claude. See Windsor’s security documentation.

Can I connect several QuickBooks companies?

Yes. Accountants and bookkeepers connect each client’s QuickBooks Online company to Windsor.ai and ask Claude to compare margins, receivables or cash across clients in one table. The free plan covers one company; paid plans scale by accounts.

What prompts can I use when analyzing QuickBooks data in Claude?

Name the object, the fields and the period. These follow the shapes teams query most through Claude:

Show profitandloss__income, profitandloss__grossprofit, profitandloss__expenses and profitandloss__netincome by month for the last 12 months. Where did the margin move?

List general ledger lines for the last 30 days with generalledger__item__tx_date, generalledger__item__account_name, generalledger__item__memo and generalledger__item__debt_amt. Flag duplicates and uncategorized expenses.

List open invoices with invoices__customerref, invoices__balance and invoices__duedate, show the agedreceivables buckets, and tell me who to chase first.

Put Google Ads and Meta Ads spend by month next to profitandloss__income for this year. What is revenue per dollar of ad spend?

How much does it cost to integrate QuickBooks into Claude using Windsor.ai?

Windsor.ai has a free forever plan, no credit card needed, and the Claude connector is included. Paid plans depend on how many accounts and data sources you connect. See the pricing page for details.

How often does the QuickBooks data refresh in Claude?

Data is fetched from the QuickBooks Online API each time you ask, so every answer reflects the current ledger, balances and open invoices rather than a scheduled snapshot.

Do you have helpful links to get started with integrating QuickBooks and Claude using Windsor.ai?

Yes. You can explore our documentation and available data fields:
