Custom policies

The IF-THEN rule engine that lets each org encode its own business rules — attendance, leave, payroll, overtime, exit, joining — without code changes.

• Categories: attendance · leave · payroll · overtime · joining · exit · shift · contract_labor · WFH · travel · compliance
• Visual rule builder for the common categories
• Versioning + rollback — every save snapshots prior rules
• Effective dating — apply from date X · retroactive option (guarded)
• Per-employee / unit / department / employment-type scoping
• Test sandbox — try a context against draft rules before saving
