You're running Xero. You're moving to Odoo, or you've decided to add it for operations while keeping Xero for the books. Either way, the question is the same: how do you actually connect the two, and what should you expect once they're talking?
This is the practical version. Connectors, sync directions, what cleanly transfers, and where the integration breaks down once you push real Australian data through it (GST, BAS, payment reconciliation). If you're still deciding whether to integrate at all or replace Xero with Odoo's accounting module, our running Odoo and Xero together guide covers that strategic decision first.
What an Odoo Xero integration actually does
An integration moves data between Odoo and Xero so you don't have to enter it twice. The most common flow is one-way: Odoo creates the invoice (because that's where your sales orders, projects, or service jobs live) and pushes it to Xero, where payments are reconciled against the bank feed. Customer master data, products, and tax codes can also sync, depending on the connector.
Some connectors offer two-way sync. In practice, that's where things get fragile. Two systems editing the same record at the same time creates conflicts. Most Australian businesses we work with end up running a one-way push from Odoo to Xero and treating Xero as a read-only ledger for the accountant.
Built-in connectors vs third-party apps
Odoo doesn't ship with a native Xero module. Every Xero connector is third-party, available via the Odoo Apps Store. The popular ones for v17, v18, and v19 are:
- Pragmatic Xero Connector: OAuth 2.0, bi-directional sync of invoices, bills, payments, contacts, and products. Most actively maintained.
- SH Xero Connector: Multi-entity support. Useful if you've got more than one Xero file.
- BI Xero Connector: Lighter-weight, focused on financial data and contacts.
- MoonSun connector_xero: Part of a broader integration toolbox, finance-data oriented.
You can also build a custom integration against the Xero API if your data flow is unusual or you need real-time syncing instead of scheduled batches. We've done a few of these for clients with multi-entity, multi-currency setups where off-the-shelf connectors couldn't keep up. Custom development costs more up front but you own the code and the logic.
What about Zapier or Make?
Both work for low-volume, simple flows: push a new Odoo customer to Xero, or send a Xero contact to Odoo. They fall over once you need invoice line items, tax codes, or payment matching. For anything beyond a handful of records a day, use a proper Odoo Apps Store connector or a custom build.
What syncs cleanly, and what doesn't
The general rule: simple records sync well. Anything with conditional logic or compliance dependencies doesn't.
Syncs cleanly:
- Customer and supplier contacts: Names, addresses, ABNs, default tax codes.
- Products and services: Code, description, price.
- Sales invoices: Header and line items, with the right tax codes mapped between systems.
- Vendor bills: Same shape as invoices, going the other way.
- Payment status: Once a payment is recorded in Xero against a bank feed, the connector can mark the Odoo invoice as paid.
Doesn't sync cleanly:
- Inventory levels: Xero doesn't really do inventory the way Odoo does. Stock counts, costing layers, and warehouse transfers stay in Odoo.
- Manufacturing and production orders: Stay in Odoo entirely.
- Bank reconciliation: Stays in Xero. Don't try to mirror it in Odoo.
- Payroll and STP: Stays in Xero or wherever you currently run payroll. The Single Touch Payroll (STP) reporting obligation doesn't move with the integration.
- BAS preparation: Whichever system holds the GST source data is where you should run BAS. Don't try to consolidate from both.
The GST and BAS angle that breaks most setups
Australian tax codes have to map exactly between Odoo and Xero or your invoices come through with the wrong GST treatment. Xero uses tax rates like "GST on Income," "GST on Expenses," "GST Free Income," and "BAS Excluded." Odoo's Australian fiscal localisation has its own equivalents (covered in our Australian localisation guide).
If you skip the tax code mapping during setup, you'll see invoices in Xero with no GST applied, or with the wrong rate. The fix is usually a one-time configuration in the connector settings, but it has to be done deliberately. The Odoo v19 Australia localisation docs list the standard tax codes shipped with the AU package, which gives you the mapping target.
For Business Activity Statement (BAS) preparation, decide upfront which system is the source of truth. If you're keeping Xero for accounting and Odoo for operations, BAS comes from Xero and Odoo just feeds it. If you're moving to Odoo's accounting module, BAS comes from Odoo and Xero gets retired. Trying to reconcile BAS from both systems creates more problems than it solves.
When integration makes sense, and when it doesn't
Integration is worth it if you're in transition (12 to 18 months on Xero while Odoo gets fully implemented), or if you've made a deliberate decision to keep Xero for the accounting layer because your accountant works in it and you don't want to retrain them.
Integration is not worth it if your goal is "use both forever." Two systems holding the same financial data will drift, even with sync. Reconciliation differences between Odoo and Xero are a regular topic with the clients we support, and the support cost compounds each year.
"Most of the businesses we help with Odoo and Xero integrations end up consolidating onto Odoo within a year. The integration buys time during cutover. After that, the reconciliation overhead starts costing more than the comfort of keeping the old system."

How to set up the integration (the high-level version)
- Pick a connector. If your data is straightforward, start with Pragmatic. If you're multi-entity, look at SH Xero Connector. If your needs are unusual, scope a custom build.
- Map your chart of accounts. Odoo's chart of accounts has to match the Xero accounts you're posting to. Document the mapping before you turn the sync on.
- Map tax codes. Every GST treatment in Xero needs an Odoo equivalent. Test with a single invoice before going live.
- Set sync direction. One-way Odoo to Xero is the cleanest default. Only enable two-way if you have a specific reason and a plan for conflict handling.
- Run a parallel period. Process a week of real invoices through both systems and reconcile. You'll find the edge cases here, not in testing.
- Decide on payment matching. Will Xero's bank feed update Odoo's invoice status, or will you manage payments separately? Pick one.
Plan on 2 to 4 weeks for setup if you're using an off-the-shelf connector and a tidy data set. Longer if you've got historical messes to clean up first. Our Odoo implementation guide for Australia covers the broader rollout context.
Frequently asked questions
Does Odoo have a native Xero integration?
No. There's no Xero module shipped by Odoo. Every connector available is third-party via the Odoo Apps Store, or a custom build against Xero's API. We use OAuth 2.0 connectors for most Australian implementations.
Can Odoo and Xero do bidirectional sync?
Some connectors support it for contacts, products, and invoices. We usually recommend one-way (Odoo to Xero) because two-way creates conflicts whenever both systems edit the same record. The exception is multi-entity setups where the rules are clearer.
Will the integration handle my BAS reporting?
The integration moves invoice and bill data between systems. BAS reporting still comes out of whichever system you've designated as the source of truth. If Xero holds your accounting, BAS comes from Xero. If you've moved to Odoo's accounting module, BAS comes from Odoo, and Xero gets decommissioned.
How long does an Odoo Xero integration take to set up?
Two to four weeks for a clean dataset using a stable Odoo Apps Store connector. Add time if your chart of accounts needs cleanup, you have multiple Xero entities, or you're integrating during a wider Odoo rollout.
Is the integration worth keeping long-term?
For most Australian businesses, no. Running two financial systems indefinitely creates reconciliation work that compounds every month. The integration is best used as a transition tool while Odoo's accounting module gets configured, then retire Xero once you're confident in the new setup.
Need help connecting Odoo and Xero, or moving off Xero entirely?
We're a Brisbane-based Odoo Silver Partner, and we've set up dozens of Odoo Xero integrations across Queensland, NSW, and Victoria. We can scope a connector setup, build a custom integration, or help you transition fully to Odoo's accounting module without losing your historical data.
If you want to talk through what makes sense for your business, book a free consultation. We'll look at your current Xero setup and tell you honestly whether integration or full migration is the better path.
