Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
OnPay
- OnPay operates only in the United States, so the first international hire means a second payroll vendor and a separate compliance model.
- There is no native mobile application, only a responsive web interface, which employers with field or shift-based staff notice immediately.
- The HR functionality is administrative and does not replace an HRIS, so performance, learning and any real workflow automation need another product.
- Time and attendance is handled through integrations rather than natively, meaning hours arrive from a third-party system that has to be reconciled when it disagrees with payroll.
- Reporting is functional but limited, and companies that want cost analysis by department, project or location generally export to a spreadsheet rather than build it in the product.
UKG Pro
- No access to super-user privileges or advanced database customization
- Limited system procedure access for advanced administrative functions
- No direct host access via SSH, Telnet, or remote desktop connectivity
- Requires paid technical support subscription for assistance beyond standard support
