The verdict in three sentences
An HR director of a Singapore mid-market firm who automates onboarding, leave and e-signature saves 45 hours per month of admin and brings contract turnaround from 5 days to 1. An HRIS SaaS costs 4 to 9 EUR/employee/month; a custom workflow automation costs 18,000 to 45,000 EUR for specific processes. ROI lands between 10 and 16 months, with 6 hours saved per hire.
