Welcome to the One-Stop Payroll (OSP) initiative powered by APEX platform.

APEX (opens in new tab) is an API management solution developed by GovTech that enables government agencies to securely share their APIs with developers from other government agencies and businesses. With APEX, developers can discover and access well-documented APIs provided by government agencies to exchange data and develop solutions that improve the overall experience of citizens' services.

As a software developer, you can streamline your payroll software integration process by following our step-by-step guide to connect with the APEX platform and access the necessary CPFB, IRAS and MOM APIs.

For businesses and employers, you can explore and adopt OSP-ready payroll software that consolidates payroll services into a single, convenient “one-stop” platform, enabling you to boost operational efficiency and manage payroll more effectively.

We look forward to collaborating with you to drive innovation and efficiency for payroll software and the digital ecosystem.
