Excerpt · Section II

The Workday-counted headcount is not the buyer-counted headcount.

Workday prices the HCM subscription against a defined headcount metric: the number of workers the tenant manages across a defined measurement period, with a small set of exclusions for contingent labour configurations and inactive records. The metric is published, but the application is not always uniform across renewals, and the trailing-period read is not always the read the buyer would compute from its own HRIS or payroll records.

The renewal price is anchored on Workday’s headcount read. The reconciliation against the buyer’s read is the first commercial decision of the renewal.

The Admodum reconciliation protocol runs the headcount metric against the buyer’s authoritative HR source, the buyer’s payroll source, the tenant configuration and the published Workday metric definition. Where the three numbers diverge, the divergence is investigated, documented and either reconciled (where the Workday read is correct) or contested (where the Workday read is high). The reconciliation result is the headcount position the buyer takes into the renewal.

This paper covers the renewal methodology Admodum applies across the twelve-month preparation cycle: the headcount reconciliation, the module rationalisation, the Workday Extend scope, the Illuminate AI sizing, the deployment-partner separation and the Year-One framing.
