If Workday is your HR system of record, you are almost certainly keeping it. Payroll and benefits are not moving because recruiters dislike the requisition screen.
The realistic comparison is running dedicated recruiting software alongside Workday and syncing hires back into it. That is a common pattern, and the questions worth asking are how new hires flow into the HCM, who owns the handoff, and whether your organisation tolerates a second system at all.
Edvenity covers job posting, pipelines, AI interviews, assessments, and screening evidence, the recruiter-facing half. It does not do payroll, benefits, performance, or workforce planning, and is not trying to. Teams needing one system for the entire employee lifecycle are not the audience for this comparison.
