About
Workday PSA is an enterprise project and resource management product built on the Workday platform, designed to help professional services firms manage the full delivery lifecycle — from project pursuit and staffing through billing and revenue recognition — in the same system that runs their HR, finance, and planning. Workday built PSA to eliminate the overhead of reconciling disconnected project management, time tracking, and financial reporting tools. Its core technology is native to Workday's unified data model, meaning project financials, resource costs, and workforce data are always synchronized.\n\nWorkday PSA covers project planning, resource capacity and skills-based staffing, time and expense capture, client billing, and revenue recognition under ASC 606 and IFRS 15. Because it shares a data layer with Workday HCM, project managers have real-time visibility into employee availability, cost rates, and utilization without manual data pulls. The product targets enterprises with complex, multi-geography service delivery operations: consulting firms, technology implementation partners, and services divisions of product companies.\n\nWorkday PSA competes with Certinia, Unit4, and Microsoft Dynamics 365 Project Operations. Its differentiator is native integration with Workday HCM and financials, eliminating reconciliation across multi-vendor stacks and providing a single source of truth for services performance. For enterprises already on Workday, PSA is a natural extension that reduces total cost of ownership.
