Foundation layer

Core HR / HRIS

The system of record for people data.

Holds the employee record - job, compensation, reporting lines, documents, time off - and usually anchors every other HR system through integrations.

Where AI-native alternatives are emerging

Suites are adding conversational self-service and AI-drafted documents on top of the record. The record itself remains the hard-to-replace layer.

Typical use cases
  • Employee records and org structure
  • Onboarding and offboarding workflows
  • Time off and absence
  • Manager and employee self-service
When organizations need it
  • Spreadsheets no longer reflect who works where, for whom, at what cost
  • You run payroll or benefits in more than one country or entity
  • Managers need self-service for approvals, time off and org changes
Questions to ask vendors
  • How clean is the data model for multi-entity, multi-country organizations?
  • Which integrations are native, and which rely on a third-party connector?
  • How are effective-dated changes, audit trails and permissions handled?
  • What does implementation realistically take - internal hours, partner fees, timeline?
