Workday provides cloud-based human resources and financial management software used by large and mid-sized organizations to manage payroll, employee records, recruiting and financial planning. Its software replaces older on-premises HR and finance systems with cloud-delivered applications that are updated continuously by Workday rather than requiring customers to manage their own software upgrades and infrastructure. Human resources and financial systems are core operational software that organizations rarely switch once implemented, since migrating employee and financial data to a new system is costly and risky, giving Workday a sticky, subscription-based customer base. The company's growth has come both from adding new enterprise customers and from expanding the modules and services existing customers purchase, as Workday has broadened its platform beyond its original HR and finance functions into areas like planning and analytics.
