Can an AI agent do my bookkeeping?

Much of the routine work, yes: matching bank transactions, categorising expenses, drafting invoices and bills, finding missing receipts and chasing overdue invoices. The builders below still approve payments, tax decisions and unusual items themselves, and a CPA below says he still answers his system's questions and makes the judgement calls.

Does Xero or QuickBooks have an MCP server?

Both do. Xero publishes an official open-source MCP server (@xeroapi/xero-mcp-server) and a hosted remote MCP server. Intuit publishes an open-source QuickBooks Online MCP server that runs on your computer and needs an app registered on the Intuit Developer Portal.

Should I use Xero or QuickBooks with an AI agent?

Both have MCP servers. One builder below switched to Xero after QuickBooks blocked his bot, while another runs her voice-call bookkeeper on QuickBooks Online through Grok Bot's connector. Pick the one your accountant supports, then test the agent on one month of data.

Will an AI bookkeeper replace my accountant?

Not for most businesses. Agents take over the repetitive matching and chasing, which shrinks the bill, but year-end accounts, tax returns, payroll and advice still need a qualified person. Nothing here is tax or accounting advice.

Which AI tools do people use to let an AI agent do your bookkeeping (Xero and QuickBooks)?

Across the 18 sourced use cases in this guide, the most used tools are Grok Bot, Claude Code, QuickBooks, Claude, OpenAI Codex.

How much does it cost to get started?

0 of the 18 use cases can start on a free plan. The most common paid starting price is $30/mo (7 use cases). Prices come from each tool's official pricing page.

How long does setup take?

1 of the 18 use cases lists a setup time of an hour or less. Each card shows the setup time the builder reported.

Are these real examples?

Yes. Every use case links to its public source (an X post, a Hacker News thread or a GitHub repo) with the author and date, so you can check it yourself.

How to let an AI agent do your bookkeeping (Xero and QuickBooks)

Short answer: Connect the agent to your accounting software, not your bank login. Xero and Intuit both publish free, open-source Model Context Protocol (MCP) servers, the standard way agents connect to outside tools, so Claude, Claude Code, Codex or Grok Bot can read your chart of accounts, match bank transactions, draft invoices and bills, and chase missing receipts. Write your categorising rules down once, let the agent work through the backlog and leave you a list of questions, and keep every payment, tax decision and large reclassification for yourself. Xero costs $27 to $97 a month in the US and QuickBooks Online Simple Start lists at $38 a month; the MCP servers themselves are free.

Real setups where small businesses and a CPA hand the routine bookkeeping to an agent: daily Xero reconciliation, a voice-call bookkeeper on QuickBooks Online, overnight receipt matching and a finance agent that never pays anything. 18 matching use cases below, each with a public source.

Step by step

Decide what the agent may and may not do. Write it down before you connect anything. One company that sells grooming products to barbershops runs a finance agent that matches transactions, prepares bookings, tracks VAT and cash position and chases missing receipts, but it never pays anything; price changes, tax calls and big reclassifications go to the owner. That split is a good default.
Keep the bank out of it. Your bank's feed already lands in Xero or QuickBooks, so the agent never needs your banking login. Large US banks including JPMorgan, Bank of America, Wells Fargo and Morgan Stanley have been blocking third-party agents and rewriting their terms, and JPMorgan warns that what an agent does with your login is on you. Read your bank's current terms before connecting anything directly.
Connect your accounting software. For Xero, use Xero's official MCP server (@xeroapi/xero-mcp-server on npm) with a Custom Connection from the Xero developer portal, or Xero's hosted remote MCP server; it can list accounts, contacts, invoices and reports and create invoices. For QuickBooks Online, Intuit's open-source QuickBooks Online MCP server runs on your computer after a one-time sign-in through an app you register on the Intuit Developer Portal, and you can switch off write, update and delete tools so the agent can only read. Grok Bot users below use the QuickBooks Online connector from Grok Bot's connector list. One builder moved from QuickBooks to Xero because Xero's API let his bot in.
Write your rules together. Spend one session with the agent writing down how you categorise things: which vendors map to which accounts, what counts as a business expense, how you treat transfers and owner draws. One bookkeeper bot works from rules its owner wrote with it, and a CPA below builds reusable skills for transaction matching, journal entries and monthly bank reconciliation.
Let it work the backlog and leave questions. Start with one month. Ask the agent to match receipts and bank lines, find missing invoices and remittances in your email, and list anything it is unsure about instead of guessing. One owner's bot worked through April overnight, searched personal cards for possible business expenses and left her a list of questions for the morning.
Make it a routine with a short report. Once a month is clean, run it daily or weekly. One business owner's Grok Bot reconciles Xero every day and emails clients with overdue invoices. Another founder, whose French accounting software had no API, built and open-sourced one so the agent does the books and they only approve. Keep your accountant in the loop for year-end, payroll and tax filing.

What it costs

Xero (US): $27, $59 or $97 a month. Early, Growing and Established plans per organization, with unlimited users; Xero's US page shows an introductory discount for new customers.
QuickBooks Online (US): From $38 a month (Simple Start). Essentials $85, Plus $140 and Advanced $340 list prices; new customers are offered 50% off for 3 months. A free plan with 1 user and 1 bank connection is also listed.
Xero and QuickBooks MCP servers: Free and open source. Both are MIT-licensed. QuickBooks requires registering an app on the Intuit Developer Portal; Xero needs a Custom Connection or a bearer token.
The AI agent: Varies. Claude, Claude Code, Codex and Grok Bot have their own plans; check each tool's pricing page.
Your accountant: Varies. Still worth paying for year-end review, tax returns and anything the agent flags as a judgement call.
