This integration helps automate your financial operations, keep your books squeaky clean, and cut down on manual work.

Whether you’re syncing invoices, re-invoices, reconciling bills, or managing bank transactions — this connector streamlines everything.

Let’s walk through the full setup and integration process in a way that’s easy to follow, even for busy developers and finance teams.

⚙️ Key Features of Xero Odoo Connector

  • Automatic Data Sync: Sync invoices, bills, payments, contacts, and more — in real time.
  • End-to-End Financial Visibility: Combine ERP and accounting into one cohesive system.
  • Easy Setup: No tech wizardry required — just follow the steps.
  • Smart Reporting: Get richer reports by merging Odoo and Xero data.
  • Custom Workflows: Tailor syncs to your unique business needs.
  • Secure Transfers: Encrypted data exchange keeps everything safe.

🚀 Step 1: Pre-Requisites for Integration

Before diving in, you’ll need a few things installed and ready:

🔹 Required Odoo Modules:

  • Xero Odoo Connector
  • Queue Job
  • Queue Job Cron Job runner
     (All freely available via Odoo Community Association – OCA)

🔹 External Python Dependency:

bash

pip install pkce

The pkce package is essential for handling secure OAuth authentication with Xero.

🔐 Step 2: Set Up Your Xero Developer App

  1. Head to Xero Developer Console
  2. Login and go to My Apps
  3. Choose Mobile or Desktop App as the app type
  4. Add your App Name, set the Redirect URI to:
     https://api-explorer.xero.com/
  5. Once the app is created, copy the Client ID

🔄 Step 3: Authenticate Xero in Odoo

  1. In Odoo, go to the Xero Connection menu
  2. Create a new connection
  3. Fill in:
    • Organization Name
    • Client ID
  4. Click AUTHENTICATE

Xero will redirect you to a page to select your organization and grant access.

Once approved:

  • You’ll be shown a code
  • Copy and paste it back into Odoo
  • Click GET ACCESS TOKEN

🎉 Congrats! Your Odoo and Xero are now officially connected.

🕒 Note: Xero tokens expire every 30 minutes. Use the REFRESH TOKEN button in Odoo to keep things alive.

📥 Step 4: Import Data from Xero to Odoo

Start by importing the foundational data first:

  1. Contacts
  2. Products
  3. Taxes
  4. Chart of Accounts

Then move on to:

  • Sales Orders
  • Purchase Orders
  • Invoices
  • Bills
  • Bank Accounts

This step ensures data integrity and a smooth sync later on.

📤 Step 5: Export Data from Odoo to Xero

Same idea here — export base records first:

  1. Contacts
  2. Products
  3. Taxes
  4. Accounts

Then export financial transactions (Sales, Purchases, Invoices, etc.)

This structure keeps your records organized and prevents sync issues.

📊 Step 6: Monitor Sync with Queue Jobs

The Xero Connector uses Queue Jobs to manage large datasets.

Go to Job Queue module in Odoo:

  • Track imports/exports in real time
  • See which queues are in progress, completed, or failed
  • Use the Fail Log Messages to diagnose and fix any issues

No more guesswork — you’ll always know what’s happening behind the scenes.

✅ Final Thoughts

Integrating Xero with Odoo 18 is one of the smartest moves you can make if you want smoother financial workflows, better reporting, and fewer errors.

By automating the data exchange, your team can focus on strategy, not spreadsheets. Just install the modules, link your Xero app, authenticate, and let Odoo handle the rest.

Whether you’re managing 100 transactions or 10,000 — this integration scales with you.
