ChatGPT + Xero: What the Integration Can (and Can't) Do in 2026
There’s no official Xero app in ChatGPT. Xero does maintain an official MCP server that bridges its accounting API to AI assistants — but it’s a local, developer-oriented package (installed via npx, authenticated with your own Xero app credentials), and ChatGPT’s custom connectors expect a remote HTTPS endpoint. So connecting ChatGPT to Xero in 2026 means either hosting a bridge yourself or going through a third-party MCP host. It’s doable, it’s real, and it’s firmly a developer project — not a toggle. And even fully wired, ChatGPT only touches your books when you’re in a chat asking it to.
Worth knowing: Xero’s own AI energy is going into JAX (Just Ask Xero), its in-product agent that handles bank reconciliation and invoice data extraction inside Xero itself — powered by Claude under Xero’s Anthropic partnership — not into a ChatGPT app.
Here’s what actually works today, how to set it up, and what to use if you want your books worked without you.
What ChatGPT can actually do with Xero
- Query your accounts in plain English — once connected via MCP, ChatGPT can pull invoices, contacts, and reports: “who hasn’t paid yet,” “what’s my revenue this quarter,” “list overdue invoices.”
- Work with accounting objects — Xero’s official MCP server exposes tools for invoices, contacts, payments, and reports, so ChatGPT can read and, depending on the tools you enable, draft records.
- Analyze what it reads — summaries of aged receivables, cash-flow narratives, quarter-over-quarter comparisons: the reasoning layer is where ChatGPT genuinely adds value over Xero’s own screens.
- Go through a third-party host instead — services like Composio and CData run hosted Xero MCP endpoints you can paste into ChatGPT, trading a self-hosting project for a third party in your accounting data path.
What doesn’t exist: an official Xero app in ChatGPT’s directory that you enable with one click. (On the Claude side, Xero is in the official connectors directory — see Claude + Xero.)
How to set it up
- Be on a ChatGPT plan with Developer Mode — custom MCP connectors require Plus, Pro, Team, Enterprise, or Edu.
- Get a remote MCP endpoint for Xero: host Xero’s official MCP server behind an HTTPS bridge yourself, or use a hosted third-party Xero MCP endpoint.
- In ChatGPT, open Settings → Apps & Connectors → Advanced settings, toggle Developer Mode on, and create a connector with that endpoint URL.
- Authenticate to your Xero organisation (via your Xero app’s credentials or the host’s OAuth flow), then ask about your accounts in a chat.

The limits that actually matter
- The setup is the product’s biggest limit. A one-click experience doesn’t exist; a small-business owner without a developer will find the honest answer is “not easily.”
- It doesn’t run on triggers. There’s no “when an invoice falls overdue, chase it” or “when a bill arrives, record and flag it.” ChatGPT reads your books when you prompt it — nothing fires on a Xero event, and nothing runs while you’re away.
- Session-bound. Insights stay in the chat. ChatGPT won’t email a customer about an overdue invoice, log a new client in your CRM, or put a follow-up on your task list as part of a flow.
- Credentials deserve care. Whether self-hosted or third-party, you’re routing accounting data through infrastructure you set up — treat tokens and scopes accordingly.
If you want Xero work that runs on its own: Carly
The moment you want your books worked — overdue invoices chased automatically, payment reminders sent the day they’re due, new clients logged in your CRM the moment they’re invoiced — you’ve crossed past what a chat connection is for.
That’s where Carly fits. Carly is an AI executive assistant that acts on triggers, 24/7, in the cloud:
- Fires on events — an invoice falls overdue, a payment lands, a schedule hits, and Carly acts; your laptop doesn’t need to be awake.
- Actually sends and updates — drafts and sends email on Gmail and Outlook, updates your CRM, manages tasks, so the follow-up happens instead of being suggested.
- No-code setup — say “follow up on unpaid invoices politely after 7 days” in plain English; Carly interviews you and builds the workflow. No MCP servers to host.
- Connects to everything — Xero is one of 200+ native integrations, and anything else works via your own API key, pasted on carlyassistant.com/integrations.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See the Xero integration page for what Carly can do with your organisation.

The ChatGPT route gives you an analyst you summon over your books. Carly is a bookkeeping colleague that keeps your receivables moving while you do something else.
Frequently Asked Questions
Does ChatGPT work with Xero?
Yes, but not out of the box. There’s no official Xero app in ChatGPT. Xero maintains an official MCP server, and you can connect it to ChatGPT via Developer Mode — either by hosting a remote bridge yourself or using a third-party hosted Xero MCP endpoint.
Is there an official Xero app in ChatGPT?
No, not as of July 2026. Xero’s official AI work is its own in-product agent, JAX (Just Ask Xero), plus the developer-facing MCP server. Xero does have an official connector in Claude’s directory — the ChatGPT side remains DIY.
Can ChatGPT chase overdue invoices or send payment reminders automatically?
No. ChatGPT only acts inside a conversation you start — there are no event triggers, so nothing happens when an invoice falls overdue. For automatic, trigger-based follow-ups that actually send email, you need an agent like Carly.
What is JAX in Xero?
JAX (Just Ask Xero) is Xero’s built-in AI agent, focused on automating work inside Xero itself — bank reconciliation and invoice data extraction — and answering questions about your numbers. It runs on Claude via Xero’s partnership with Anthropic and is separate from any ChatGPT connection.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
