The Need for Integration in Modern HR
Many companies upgrading to platforms like Workday, SAP SuccessFactors, or Oracle HCM quickly discover a gap—payroll doesn’t always play well with HCM out of the box. For outsourced payroll to truly empower HR, it must integrate seamlessly with your existing systems.
What Integration-Ready Payroll Looks Like
✅ API-Based Connectivity
Modern payroll platforms should support secure, real-time APIs to sync employee records, pay adjustments, and time data directly from your HCM.
Integration must respect compliance boundaries. Whether it’s CPF in Singapore or MPF in Hong Kong, your system should automatically localize the rules.
✅ Bi-Directional Data Flow
Integration isn’t one-way. Your payroll provider should also send results back to your HCM—for compensation dashboards, general ledger updates, and tax reporting.
✅ Unified Self-Service Experience
A true integration enables employees to access payslips, tax forms, and leave balances through a single platform, improving HR service delivery.
What to Ask Prospective Vendors
Do you have a pre-built Workday (or other HCM) connector?
What data formats and sync frequency do you support?
Can your platform scale across multiple countries?
How do you handle mid-cycle updates and retro adjustments?
