Product category and breadth
Ziantrix: Ziantrix is an AI-native HR operations and payroll-validation layer, not a full record-of-employment system — it is designed to sit on top of existing payroll and HR data and resolve queries, validate payroll, and enforce compliance workflows.
GreytHR: GreytHR is best understood as Core HR + payroll + attendance suite. Deep India statutory payroll coverage (PF, ESI, PT, TDS, LWF) refined over 20+ years, strong CA/payroll-consultant ecosystem.
Indian statutory compliance
Ziantrix: Ziantrix prepares PF, ESI, PT, and TDS workflow outputs and validates payroll-sensitive inputs before disbursement, while leaving final filing decisions with the customer.
GreytHR: GreytHR's Indian statutory compliance depth should be verified directly: Workflows are largely form- and report-driven; AI-native employee self-service and proactive anomaly detection are limited.
Onboarding and migration
Ziantrix: Ziantrix pilots typically start with a narrow slice of employee data, policy documents, payroll rules, and query categories, expanding only after a 45-day pilot proves value.
GreytHR: Migrating off GreytHR is low-to-moderate effort. most data exports (employee master, payroll history, attendance) are CSV-friendly
Pricing model
Ziantrix: Ziantrix leads with a free 45-day pilot, then prices against employee count, workflow volume, AI resolution volume, and support tier.
GreytHR: GreytHR pricing: Per-employee/month, tiered by modules (core HR, payroll, time & attendance).
Security and governance
Ziantrix: Ziantrix publishes trust, privacy, AI transparency, subprocessor, and security overview pages for procurement review, and is GCP-hosted with RBAC and audit logging, with SOC 2 readiness in progress.
GreytHR: GreytHR buyers should request current audit reports (SOC 2 / ISO 27001), data residency terms, and subprocessor lists as part of evaluation — particularly important for indian smb to mid-market (10-3000+ employees) deployments.
