Why we built this

Payroll errors cost more than you think.

Manual register audits miss edge cases - overpayments, statutory breaches, reconciliation gaps - and every miss becomes penalties, clawbacks or broken employee trust. HONO's Anomaly Detection agent scans the entire register before disbursement, every cycle.

Good to know

Are these errors based on real payroll scenarios?+

Yes. Every error class in the game - statutory ceiling breaches, component mismatches, impossible day counts - maps to a real anomaly class the agent catches in production.

Which countries' payroll rules are included?+

The register switcher covers multiple countries, each with its own currency, components and statutory rules - PF/ESI for India, GOSI for GCC and more.

Can I use this to train my payroll team?+

Absolutely - many teams use it as a fun onboarding drill. Share your score with the team and see who beats it.
