OnPay’s site includes customer quotes and claims about saving time and simplifying payroll/HR, but publicly accessible materials in this research snapshot were mostly marketing testimonials rather than detailed, independently verifiable case studies.
**Critical evaluation:**
- **Metrics gap:** No independently audited ROI figures were found in the sources reviewed.
- **Recommendation:** Procurement teams should request:
- Implementation timeline distribution (median time to first payroll),
- Tax filing accuracy SLAs / remediation policy,
- Documented incident history and support response targets.
