A leave management Xero integration syncs approved leave with Xero payroll — so leave deductions, accrual calculations, and payslip entries flow automatically from your leave management system into your payroll run. For Australian and New Zealand businesses where Xero is the dominant accounting platform, this integration eliminates the manual data transfer between leave tracking and payroll that creates errors and delays.
In 2026, over 400,000 Australian businesses use Xero for accounting and payroll. Connecting leave management to Xero ensures that every approved leave entry results in correct pay calculations without manual intervention.
Key takeaways
- Leave management Xero integration syncs approved leave with Xero payroll for automatic pay calculations.
- Leave accruals, deductions, and payslip entries transfer automatically from the leave management system.
- Integration typically supports leave type mapping, accrual rule configuration, and single touch payroll (STP) compliance.
- Setup requires OAuth authentication between your leave management tool and Xero.
- The integration is essential for Australian and New Zealand businesses using Xero for payroll.
How Xero integration works
The integration connects your leave management platform to Xero through the Xero API, syncing leave data that impacts payroll calculations. Here is the typical workflow:
When leave is approved:
- The leave management system records the approved leave and updates the employee’s leave balance.
- The integration pushes approved leave data to Xero Payroll.
- Xero calculates the pay impact based on the employee’s pay template and leave type.
- The leave entry appears in the employee’s next pay run in Xero.
Leave accrual synchronization:
- The leave management system calculates accruals based on configured rules.
- Accrual data syncs to Xero to update employee leave balances.
- Xero reflects current accrual balances in payslips and reporting.
Pay run flow:
- When the payroll team processes a pay run in Xero, approved leave from the leave management system is already in Xero.
- Leave deductions and payments are calculated automatically.
- Payslips include accurate leave balances and leave taken during the period.
Benefits of Xero integration
1. Eliminates double data entry
Without integration, payroll teams manually transfer approved leave from the leave management system to Xero. This creates two risks: errors in manual entry, and delays when leave approved after payroll is processed doesn’t make the current pay run. Integration eliminates both.
2. Ensures payroll accuracy
The Australian Taxation Office (ATO) reports that incorrect leave payments are one of the most common payroll errors in Australian businesses. Integration ensures that the leave data in payroll matches the leave data in your leave management system exactly.
3. Supports STP compliance
Single touch payroll (STP) requires accurate reporting of salary, wages, tax, and superannuation information each pay run. Leave payments that are incorrect in Xero create STP reporting errors. Integration ensures the data flowing into Xero is accurate from the source.
4. Improves accrual visibility
When leave accruals sync between systems, employees and managers see accurate balance information in both the leave management tool and Xero. This transparency reduces balance disputes and accrual-related payroll queries.

Setting up the integration
Step 1: Verify Xero API support
Check that your leave management tool supports the Xero API (not just CSV export). Xero API integration provides:
- OAuth 2.0 authentication
- Real-time data sync
- Automatic leave type mapping
- Pay run integration
- Employee data synchronization
Step 2: Connect to Xero
- In your leave management tool, navigate to integration settings.
- Select “Connect to Xero” and authenticate with your Xero account.
- Grant the required API permissions (typically: payroll read/write, employee read).
- Authorize the leave management tool to access your Xero organization.
Step 3: Map leave types
Configure how leave types in your leave management system map to Xero pay items:
| Leave management type | Xero pay item |
|---|---|
| Annual leave | Annual leave deduction |
| Sick leave | Sick leave deduction |
| Personal leave | Personal/carer’s leave deduction |
| Long service leave | Long service leave deduction |
| Public holidays | Public holiday payment |
| Unpaid leave | Unpaid leave deduction |
Step 4: Configure sync settings
- Sync timing: Choose real-time sync or scheduled sync (e.g., daily before payroll).
- Accrual rules: Configure how accruals calculated in the leave management system sync to Xero.
- Employee matching: Map employees between systems using email or employee ID.
- Historical data: Choose whether to sync historical leave or start from the integration date.
Step 5: Test with a pay run
- Submit and approve a test leave request.
- Verify the leave entry appears in the Xero pay run.
- Process the pay run and verify the leave payment is calculated correctly.
- Check that leave balances update in both systems.

Frequently asked questions
How does leave management Xero integration work?
A leave management Xero integration syncs approved leave with Xero payroll through the Xero API. When leave is approved, it transfers to Xero as a leave entry in the employee’s pay template. The leave is then calculated automatically during the next pay run.
Is Xero integration secure?
Yes. The integration uses OAuth 2.0 authentication, and data is encrypted in transit. The leave management tool only accesses payroll and employee data needed for leave synchronization. You can revoke access at any time through Xero’s authorized apps settings.
Does the integration support single touch payroll (STP)?
Yes. Accurate leave data flowing from the leave management system to Xero ensures that STP reporting includes correct leave payments. Some integrations include pre-submission validation that checks leave data before STP submission.
Can I sync historical leave data to Xero?
Most integrations allow you to choose whether to sync historical leave or start from the integration date. Historical sync is useful when migrating from manual leave tracking to a leave management system.
Does the integration handle long service leave?
Yes. Most integrations support long service leave as a leave type with its own accrual rules and pay item mapping in Xero. Long service leave calculations vary by Australian state, so verify that your leave management tool handles the correct accrual rates for your jurisdiction.
Putting it into practice
If your business uses Xero for payroll, integrating leave management eliminates manual data transfer and reduces payroll errors. Start by verifying that your leave management tool offers native Xero API integration, then configure leave type mapping and test with a sample pay run.
