Frequently Asked Questions

How much does Workday cost per year?

Workday HCM costs $100–$300/employee/year based on company size and modules selected. For 500 employees, annual licensing costs $50,000–$150,000. This does not include the implementation project (typically $500K–$2M), annual support fees, or Workday Studio customization work.

Can custom HR software replace Workday for mid-market companies?

For mid-market companies (200-1,000 employees), custom HR software is often more cost-effective. Slickrock.dev builds custom HR platforms for $35,000 with $2,500/year maintenance. Over 5 years: $123,000 vs. $250,000–$750,000 Workday (plus implementation costs).

Why is Workday implementation so expensive?

Workday implementations require certified consulting partners (Deloitte, Accenture, etc.) at $200–$400/hr. The platform complexity, data migration requirements, and change management needs mean most implementations take 9-18 months. Custom software built for your specific HR processes eliminates this complexity by design.
