Synthetic Demo
Your HR, Finance, and Payroll numbers don't match. Here's why.
An interactive walkthrough of one headcount reconciliation scenario — from the raw delta between systems to root causes, reason codes, and case evidence. All data is synthetic.

What is wrong?
Finance counts this worker in headcount; HR excludes them because Workday classifies them as a contractor.
Why does it matter?
It inflates Finance headcount and budget against a worker HR does not treat as an employee. Repeat this across 28 workers and the totals diverge materially.
Who owns it?
HR Operations confirms the worker classification; Finance applies the agreed inclusion rule.
What should happen next?
Agree a company-level contingent-worker definition, then apply it consistently in both systems. Neither system is wrong — they use different rules.
