QuickBooks Online + Claude — Capabilities Guide

Sales & customers

Read + write

The full customer-to-cash cycle — who you sell to, what you've quoted them, what they've been invoiced, what they've paid, and what you've credited back. Anything that changes a record is marked ✎ below.

Customers

Action	What you can do / what to expect	Writes?
Find customers	Search your customer list any way you'd describe it — top 10 by total invoiced this year, anyone who hasn't bought in 12 months, customers whose days-to-pay is slipping.	—
Open a customer record	Pull up one customer in full — contact details, billing address, payment terms and current balance.	—
Create a customer	Set up a new customer from a plain description: name, billing address, contact, terms. Shown to you for approval before it's added.	✎Write
Edit a customer	Correct or update a customer's details — address, contact, payment terms.	✎Write
Deactivate a customer	Take a customer out of active use. QuickBooks keeps the record and all its history.	✎Write

Quotes & estimates

Action	What you can do / what to expect	Writes?
Find estimates	Look up quotes you've issued — by customer, date, amount or whether they've been accepted.	—
Open an estimate	See a single quote in full, line by line.	—
Create an estimate	Draft a quote from a description or a pasted proposal — e.g. 50 widgets at $12 each plus 10 service hours at $85, due in 14 days.	✎Write
Edit an estimate	Change lines, pricing or dates on a quote before the customer accepts it.	✎Write
Email an estimate	Have QuickBooks email the quote to the customer — to the address on file, or one you name. Claude confirms the recipient with you first.	✎Write
Delete an estimate	Remove a quote that's no longer live. You'll be asked to confirm the exact quote first.	✎Write

Invoices

Action	What you can do / what to expect	Writes?
Find invoices	Every invoice over $10,000 open more than 60 days; everything unpaid for one customer sorted by date; whatever slice you need.	—
Open an invoice	See a single invoice in full — lines, dates, amounts, what's been paid against it.	—
Create an invoice	Bill a customer, including turning an accepted quote into an invoice (“convert estimate #1042 to an invoice”). Set the tax code by name (“Exempt”) for the whole invoice or line by line; the currency and exchange rate come from the customer. Ask to see it before it’s created.	✎Write
Edit an invoice	Change lines, amounts, dates or terms on an existing invoice.	✎Write
Email an invoice	Send the invoice from QuickBooks to the customer, exactly as QuickBooks would — same PDF, same template, marked as sent. Claude confirms who it's going to before it goes.	✎Write
Void an invoice	Zero the invoice out but keep it on file marked Voided — the audit-trail-friendly alternative to deleting.	✎Write
Download the invoice PDF	Fetch the printable PDF QuickBooks generates for an invoice (also works for estimates, sales receipts, credit memos, refund receipts, purchase orders and payments).	—
Attach a document to a transaction	Put the source receipt, vendor invoice or signed order on the record, so the books carry the paperwork. The file has to be somewhere reachable by link — in practice a shared Drive or SharePoint folder you drop documents into. A file attached to this chat cannot be used: Claude reads it to pull out the amounts, but never receives the file itself. PDF, JPG, PNG, GIF, TIFF, CSV, TXT, RTF, XML, Word, Excel and OpenDocument; iPhone HEIC photos need converting to JPEG first.	✎Write
Process a folder of receipts	Read a shared folder, create a bill or expense for each document, attach the original to it, and move the file to an archive folder. Run it on request while you check the results; once you trust it, it can run on a schedule with nobody watching.	✎Write
Void or delete an invoice	Take an invoice out of your active books. QuickBooks normally keeps the record marked void, but it does affect your financial reports — so you're asked to confirm the exact invoice first.	✎Write

Cash sales (sales receipts)

Action	What you can do / what to expect	Writes?
Find sales receipts	Look up over-the-counter or paid-at-the-time sales by date, customer, amount or payment method.	—
Open a sales receipt	See a single cash-sale receipt in full.	—
Create a sales receipt	Record a sale that was paid at the time, so the income and the cash both land in the right place. Tax code, currency and preview work as they do on an invoice.	✎Write
Edit a sales receipt	Correct the lines, amounts or payment details on a recorded cash sale.	✎Write
Email a sales receipt	Send the receipt to the customer from QuickBooks.	✎Write
Void or delete a sales receipt	Reverse a cash sale that shouldn't have been recorded. Confirmed with you first; it moves your reported income.	✎Write

Credits & refunds

Action	What you can do / what to expect	Writes?
Find credit memos	See credits issued to customers for returns, disputes or over-billing — including any still sitting unapplied.	—
Open a credit memo	See a single customer credit in full.	—
Create a credit memo	Issue a credit to a customer — e.g. $250 against invoice #2089 for a damaged item. Takes the same tax code as the invoice it reverses, so an exempt customer stays exempt.	✎Write
Edit a credit memo	Change the amount, lines or customer on an existing credit.	✎Write
Email a credit memo	Send the credit memo to the customer from QuickBooks.	✎Write
Void or delete a credit memo	Reverse a credit that was issued in error. Confirmed with you before anything changes.	✎Write
Find refund receipts	Look up money actually refunded back to customers, by date, customer or amount.	—
Open a refund receipt	See a single refund in full.	—
Create a refund receipt	Record a refund paid back to a customer — e.g. $500 to John Smith for last week's cancelled order. Tax code, currency and preview work as they do on an invoice.	✎Write
Edit a refund receipt	Correct the amount, account or customer on a recorded refund.	✎Write
Void or delete a refund receipt	Reverse a refund recorded in error. You confirm the exact record first.	✎Write

Recurring invoices & templates

Action	What you can do / what to expect	Writes?
Find recurring templates	List the recurring invoices, bills, journal entries and other templates QuickBooks generates on a schedule — “which customers are on a monthly retainer?”	—
Open a recurring template	See one template in full — the schedule, the next date, and the lines it will post.	—
Create a recurring template	Set up a scheduled transaction from a description — “invoice ACME $2,500 on the 1st of every month starting October”. Shown to you before it's created.	✎Write
Edit a recurring template	Change the amount, lines or schedule of an existing template.	✎Write
Delete a recurring template	Stop future occurrences. Transactions it already created are untouched. You'll be asked to confirm.	✎Write

Purchasing & vendors

Read + write

The vendor-to-pay cycle — who you buy from, what they've billed you, what's still owed, and the credits you're holding against them.

Vendors

Action	What you can do / what to expect	Writes?
Find vendors	Search your supplier list — who you spend the most with year-to-date, who you've stopped buying from, who has an unapplied credit.	—
Open a vendor record	Pull up one vendor in full — contact details, terms, current balance.	—
Create a vendor	Set up a new supplier, e.g. “Quebec Wholesale Foods, terms Net 30”.	✎Write
Edit a vendor	Update a supplier's contact details, address or payment terms.	✎Write
Deactivate a vendor	Take a supplier out of active use while keeping their history intact.	✎Write

Action	What you can do / what to expect	Writes?

Open a bill	See a single vendor bill in full, line by line.	—
Create a bill	Record what a vendor has charged you — including from a PDF you drop into the conversation, with the amount, lines and due date read straight off it.	✎Write
Edit a bill	Correct the amount, expense category, due date or department on a bill.	✎Write
Void or delete a bill	Remove a bill from your active payables. Confirmed with you first, since it changes what you appear to owe.	✎Write

Find purchase orders	See what you've ordered and from whom — open, closed, by vendor or by date.	—
Open a purchase order	See a single order in full, line by line.	—
Create a purchase order	Raise a formal order — e.g. 100 lbs of flour at $1.20/lb and 50 lbs of sugar at $0.85/lb from Quebec Wholesale Foods.	✎Write
Edit a purchase order	Change quantities, pricing or delivery details on an order that hasn't been fulfilled.	✎Write
Email a purchase order	Send the PO to the vendor from QuickBooks — to the address on file or one you name.	✎Write
Void or delete a purchase order	Cancel an order you no longer want. You confirm the exact order first.	✎Write

Vendor credits

Action	What you can do / what to expect	Writes?
Find vendor credits	See credits your suppliers owe you — from over-billing or returns — including ones you haven't applied yet.	—
Open a vendor credit	See a single supplier credit in full.	—
Create a vendor credit	Record a credit a supplier has given you, so it offsets what you owe them.	✎Write

Edit a purchase	Recategorize or correct an expense entry.	✎Write
Void or delete a purchase	Remove a duplicate or mistaken expense entry, after confirming which one.	✎Write

Money movement

Read + write

Cash actually moving — payments received, bills paid, deposits banked, money shifted between your own accounts. Recording these here updates your books; it does not itself move money at a bank or card processor.

Money in — customer payments

Action	What you can do / what to expect	Writes?
Find customer payments	Everything received from one customer, what is still unapplied, or duplicates recorded twice.	—
Open a customer payment	See a single received payment and what it was applied against.	—
Record a customer payment	Log money received and apply it to the right invoice — e.g. “$5,000 from ACME Corp received today, apply it to invoice #2105”.	✎Write
Edit a customer payment	Change a payment's amount, method or note — or apply money it hasn't applied yet to the customer's open invoices, keeping everything it already pays. (Applying a bank deposit to an invoice is done in the QuickBooks screen; QuickBooks' API doesn't allow it.)	✎Write
Void a customer payment	Reverse a payment while keeping the record on file marked Voided.	✎Write
Delete a customer payment	Reverse a payment recorded in error, after you confirm the exact one.	✎Write

Open a deposit	See a single deposit and every payment grouped into it.	—
Create a deposit	Group several customer payments into one bank deposit so your books match what the bank shows as a single line.	✎Write

Delete a transfer	Reverse a transfer recorded in error, after you confirm it.	✎Write

Products, services & inventory

Read + write

The catalogue of what you sell, plus quantities on hand for anything you track as inventory in QuickBooks.

Products & services

Action	What you can do / what to expect	Writes?
Find products & services	List everything you sell with quantity on hand, spot what's out of stock, find prices that haven't been reviewed in over a year, or rank best sellers year-to-date.	—
Open a product or service	See one item in full — pricing, income account, and stock on hand if it's inventory-tracked.	—
Create a product or service	Add something new to sell — e.g. a service item “Consulting Hour - Senior” at $150/hour posting to Service Revenue.	✎Write
Edit a product or service	Change pricing, description or the account an item posts to.	✎Write
Deactivate a product or service	Retire something you no longer sell while keeping its sales history.	✎Write

Accounting & the ledger

Read + write

The accounting backbone — your account structure and the manual entries your accountant makes against it.

Chart of accounts

Action	What you can do / what to expect	Writes?
Find accounts	See your chart of accounts organized by type, or hunt for specific accounts by name or balance.	—
Open an account	See one account's details — type, sub-account, current balance.	—
Create an account	Add a new account — e.g. an expense account “Software Subscriptions” under Operating Expenses.	✎Write
Edit an account	Rename, re-parent or deactivate an account. QuickBooks does not allow accounts to be deleted, so retiring one means marking it inactive.	✎Write

Journal entries

Action	What you can do / what to expect	Writes?

Advanced look-ups

Action	What you can do / what to expect	Writes?
query_quickbooks	Ask for anything the actions above don't cover — QuickBooks' own query language, read-only. Claude writes the query; you just describe what you want (“every credit-card charge over $500 this quarter”).	—
get_changed_entities	What changed since a point in time — every customer, invoice, bill or payment created, edited or deleted since last Monday. The basis for “what happened in the books this week?”	—

People & time

Read + write

Employee records and the hours logged against them — the inputs to billing and payroll, not payroll processing itself.

Find departments	List your departments or locations — the basis for “show me revenue and expenses by department for last month”.	—
Open a department	See one department and its details.	—
Create a department	Add a new department, location or cost centre.	✎Write
Edit a department	Rename or deactivate a department. QuickBooks does not allow departments to be deleted.	✎Write

Look up an exchange rate	The rate QuickBooks holds for a currency on a given date — or the full history of rates on file.	—
Set an exchange rate	Override the rate for a currency on a date. Shown to you before it's saved.	✎Write

Customer types

Action	What you can do / what to expect	Writes?
List customer types	The segments your customers are tagged with (wholesale, retail, …). Managed in QuickBooks itself; Claude reads them for filtering and grouping.	—

Taxes

Look-up only

Tax reference data is available to look at and check, but never changed here — it's maintained by your accountant or by QuickBooks itself.

Tax codes, rates & agencies

Action	What you can do / what to expect	Writes?
Find tax codes	List active tax codes with their rates, or spot inactive ones as a clean-up opportunity.	—

Edit attachment details	Rename a document or change what it's linked to.	✎Write
Delete an attachment	Remove a document — e.g. a duplicate receipt on a bill. You confirm which one first.	✎Write

Budgets

Look-up only

Budgets can be read and analysed in depth, but not created or changed — Intuit doesn't allow budgets to be written to from outside QuickBooks. You'll still set budgets up in QuickBooks itself.

Budgets

Action	What you can do / what to expect	Writes?
Find budgets	See which budgets are active and pull the figures behind them, so they can be compared against actuals — e.g. “find any budget where actual exceeds budget by more than 10% year-to-date”.	—

Reports

Look-up only

Twenty-four standard reports, runnable for any period you name, and combinable — “run it, compare it to last year, flag anything that moved more than 25%, and write me a paragraph for the board” is one request, not four.

Financial health

Action	What you can do / what to expect	Writes?
get_balance_sheet	Assets, liabilities and equity at a point in time — “show me the balance sheet as of today”.	—
get_profit_and_loss	Income and expenses over any period, with comparisons on request — “this year against last year, month by month”.	—

get_trial_balance	Debits and credits for every account — the sanity check before you close the books.	—
get_general_ledger	The complete transaction history behind any account — e.g. everything in Travel & Entertainment for the last 90 days.	—
get_journal_report	Every transaction in a period as its debits and credits.	—
get_transaction_list	All transactions in a period in one list — filter by type, group by customer or vendor, or expand the splits.	—
get_tax_summary	Sales tax collected and owed by agency and rate for a period — your GST/HST or sales-tax liability at a glance.	—
get_inventory_valuation_summary	Quantity on hand, asset value and average cost for every inventory item as of a date.	—

Who owes you (A/R)

Action	What you can do / what to expect	Writes?
get_aged_receivables	Outstanding customer invoices grouped by how old they are — current, 1-30, 31-60, 61-90, 90+.	—
get_aged_receivables_detail	The same aging, but every open invoice listed under its bucket — what you need to actually chase.	—
get_customer_balance	What each customer owes you right now.	—
get_customer_balance_detail	The open transactions making up each customer's balance.	—
get_customer_sales	Sales totals by customer over a period — “who are my top 20 by revenue this year?”	—

get_class_sales	Sales by class — revenue stream, division, whatever you use classes for.	—
get_department_sales	Sales by department or location.	—
get_customer_income	Income, expenses and net per customer — which customers are actually profitable.	—

What you owe (A/P)

Action	What you can do / what to expect	Writes?
get_aged_payables	Outstanding vendor bills grouped by how overdue they are — the basis for “what's coming due in the next 14 days?”	—
get_aged_payables_detail	Every open bill listed under its aging bucket.	—
get_vendor_balance	What you currently owe each vendor.	—
get_vendor_balance_detail	The open transactions making up each vendor's balance.	—
get_vendor_expenses	Spending by vendor over a period — sort by total spend, or flag vendors whose costs grew more than 50% year-over-year.	—

Connection & setup

Look-up only

Housekeeping for the link between Claude and your QuickBooks company. None of these change anything inside your books.

Connection

Action	What you can do / what to expect	Writes?
connect_qbo	Get the link that connects Claude to your QuickBooks company. You sign in and approve in your own browser, so no password ever passes through the chat. If a connection is already live it just tells you so.	—
get_connection_status	Check the connection is healthy — which QuickBooks company is linked, how much longer the current authorization is good for, and which areas of the list below your own access includes. Run this first if something you expected is missing.	—
disconnect_qbo	Disconnect your QuickBooks account: the authorization is revoked at Intuit and the stored connection removed here, so it cannot be used again. Nothing in your books changes; the next request simply asks you to reconnect.	—

Worth knowing

The honest boundaries — what this deliberately will not do, and the few places where QuickBooks itself sets the rules.

Know which actions touch real records. Looking things up and running reports changes nothing. The actions marked ✎ do change your books. Claude is instructed to restate a deletion or void and get your agreement before running it, but that's a working habit rather than something the connection enforces — if you need writes genuinely prevented, use the QuickBooks permissions on the account behind the connection, a look-up-only deployment, or preview mode below.
You can always ask to see it first. Say “show me what you'd send, don't create it yet” and you get the exact document back — customer, lines, amounts, tax, currency — with nothing written. This one is enforced: an action that can't produce a preview declines rather than going ahead. It shows what is about to be sent, which is not the same as a guarantee QuickBooks will accept it — a closed period or a duplicate document number is still refused when you go ahead.
It cannot see your bank feed. The For Review list — transactions downloaded from your bank before you match or add them — is not available to any outside application; Intuit licenses that data and does not expose it. Claude sees transactions once you have accepted them into the books, never before, and matching stays a QuickBooks task.
Anything Claude creates posts straight to your books, not to For Review. So when the bank transaction for a bill or expense Claude entered later arrives in your feed, match it to what is already there rather than adding it — adding would create a duplicate.
It won't move actual money. It records payments, deposits and transfers in your books, but it cannot charge a credit card or push funds — that's a separate Intuit service that is deliberately not switched on here.
It can read and analyse budgets but cannot create or change them. Intuit doesn't allow budgets to be written from outside QuickBooks. You'll still set those up in QuickBooks itself.
Some things can only be deactivated, never deleted: accounts, classes, departments, payment terms and payment methods. QuickBooks itself doesn't allow deletion for these.
“Delete” on most transactions is really a void. QuickBooks keeps the record marked void rather than erasing it. It still removes the document from your active workflows and changes your financial reports, which is why it always asks first.
It won't touch who has access to QuickBooks. User permissions are managed by your QuickBooks Admin in QuickBooks itself.
It never acts on its own. Every action starts from something a specific person typed in a specific conversation. The one exception is one you choose: once you trust the document inbox, it can be set to run on a schedule.
It doesn't work with QuickBooks Desktop. This is for QuickBooks Online only (Simple Start, Essentials, Plus or Advanced).
Nothing is copied or stored anywhere new. Every question results in a fresh look at QuickBooks at that moment; there's no separate database and no cached copy of your books.
Everyone shares one QuickBooks connection today. In the current setup, everyone you've granted access to sees the same QuickBooks company, and actions appear in QuickBooks' audit log under the single connected account. Connecting each person to their own QuickBooks login instead — so QuickBooks' own audit log reflects who specifically did what — is supported and can be switched on for your company.
Access can be scoped by area — per connector, and per person. A deployment can expose everything, or just sales, purchasing, reporting, banking, ledger, catalogue, people, admin, or a mix — and can be made look-up only. Beyond that, each person's own access can be set by their Microsoft group or role, which can only ever narrow what the connector offers, never widen it. Anyone can run the connection check to see which areas they have, so “why can't I see X?” answers itself. Your integration administrator sets this up.
An internet outage stops both ends. Both Claude and QuickBooks are cloud services, so neither is usable during an outage. QuickBooks itself is unaffected once you're back online.
