6 Best AI Automation Tools for Xero in 2026
Xero does more of the books on its own than most people use. Bank rules code the recurring transactions, repeating invoices go out on schedule, reminders nudge customers after a set number of days, and document capture turns bills and receipts into drafts. JAX, Xero’s AI companion, is adding more on top, though its payment follow-ups are still marked coming soon.
What Xero never sees is your inbox or your calendar. The client who replied “paying Friday” gets the same reminder template anyway, the receipt stays in an email, and nobody tells you Michael still owes two invoices before your call with him. Below are six tools that automate Xero, ranked by how much they take off your plate.
TL;DR: The best AI automation tool for Xero for most people is Carly. You connect Xero once, then chase late payers, file receipts and ask what’s owed by email or text, across all of your mailboxes and calendars. For wiring Xero into a long tail of other apps, Zapier or Make.
1. Carly
Carly is an AI agent with its own real email address that connects to Xero and thousands of other apps. You write to it in plain language and it does the work:
- “Before my 2pm with Michael, tell me which of his invoices are unpaid and how late each one is.”
- “Chase every Xero invoice more than 14 days overdue as a reply on my last thread with that client, and hold them for approval.”
- “Find this month’s receipts in my inbox and log each one as a draft bill in Xero.”
What makes it different: Xero’s reminders are templates on a timer. Carly reads your Gmail and Outlook mailboxes and your calendars, all of them, so the chase lands as a normal reply in a thread the client already knows, the receipt gets filed from the email it arrived in, and the overdue balance reaches you before the meeting. It also runs on its own: a free Zapier-style workflow can fire the moment a supplier invoice hits your inbox, or you can hand the whole receivables job to one of Carly’s agents. More on that in AI agents that send invoices and reminders.
Best for: Owners and bookkeepers whose finance work really happens in email: the payment promise, the receipt, the client asking for a copy.
Pricing: Free Zapier-style workflows; AI agents from $35/month
2. Xero’s own automation and JAX
Xero runs bank rules, repeating invoices, scheduled invoice reminders, Smart Document Capture for bills and receipts, and auto bank reconciliation natively. JAX answers questions about your numbers and drafts invoices and quotes, and XeroForce, a plain-language agent builder, is in early access.
What makes it different from Carly: Everything here works on data already inside Xero, and the newer AI pieces roll out by plan and region. Nothing reads the client’s reply in your mailbox or checks your calendar for who you’re meeting tomorrow. Carly works from both.
Best for: Rules-based bookkeeping that repeats every month.
Pricing: Included on Xero plans; JAX features vary by plan and region
3. Zapier
Zapier links Xero to thousands of apps with trigger-action Zaps, such as creating a Xero invoice when a Stripe payment comes in, with AI steps available for drafting and parsing.
What makes it different from Carly: Each Zap does exactly what it was built to do, every time, and you design and maintain all of them. Carly takes this morning’s request in a sentence and handles the wiring. See Zapier alternatives.
Best for: Moving Xero records into niche apps with no judgment call in the middle.
Pricing: Free plan; paid from ~$19.99/month
4. Make
Make builds Xero scenarios on a visual canvas, with routers, iterators and error handling for jobs like matching a batch of payouts to open invoices.
What makes it different from Carly: Fine control, plus a canvas to debug when Xero returns something unexpected. Carly replaces the canvas with a message. See Make alternatives.
Best for: Ops-minded users building multi-step Xero scenarios.
Pricing: Free plan; paid from ~$12/month
5. n8n
n8n has a built-in Xero node for contacts and invoices, an HTTP node for the rest of the API, and AI agent nodes, and you can self-host it so financial data stays on your own servers.
What makes it different from Carly: The Xero node covers a narrow slice, so serious builds lean on raw API calls you write and keep working. Carly is managed, and its workflows start from plain language. See n8n alternatives.
Best for: Developer-led teams that want Xero automations on their own infrastructure.
Pricing: Free self-hosted; cloud from ~€20/month
6. The Xero API, MCP server and a script
Xero publishes an accounting API and an official open-source MCP server. A Custom Connection gives one organisation machine-to-machine credentials, so a script or an AI client can read and write invoices and contacts. If you only want to ask about your numbers in a chat, Claude has a read-only Xero connector.
What makes it different from Carly: You set up the connection, run the code, guard the secret and notice when it breaks, and nothing acts unless you ask or schedule it. Carly gets the same outcomes from an email. See Xero MCP for the developer route.
Best for: Developers who want direct control of a single Xero organisation.
Pricing: ~$5/month per Custom Connection in the US, plus your time

FAQ
Does Xero have built-in automation? Yes. Bank rules, repeating invoices, invoice reminders, document capture and auto bank reconciliation all run natively, and JAX layers AI on top as it rolls out. The email side stays manual: the personal chase, the receipt sitting in an inbox, the heads-up before a client meeting. That is the part Carly takes over.
What is the best way to automate Xero with AI? For work that runs without you, Carly: describe the outcome and it acts in Xero, with context from all of your mailboxes and calendars. For trigger-action plumbing between apps, Zapier or Make.
Can Carly chase overdue Xero invoices from my own email? Yes. It checks which invoices are past due in Xero, writes each chase as a reply from your mailbox, and holds them for approval until you tell it to send on its own. Emily, a bookkeeper, can have it running for every client by Friday, or you can book a call and set it up with the team.
How do I connect Xero to Carly? In Xero’s developer portal, create a Custom Connection for your organisation, then copy its client ID and client secret and paste them under Custom API Keys at carlyassistant.com/integrations.

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."
