An Applicant Tracking System (ATS) is recruiting software that manages the hiring process for open roles from start to finish. It handles posting jobs to boards and career sites, collecting and parsing applications and resumes, screening and ranking candidates, scheduling interviews, and moving applicants through defined hiring stages until an offer is made. An ATS is primarily built for permanent, employee (W-2) hiring and often acts as the front end that feeds new hires into a Human Resource Information System (HRIS). It is a core piece of recruiting technology, and it is distinct from a Vendor Management System, which manages staffing suppliers and the contingent workforce, and from a Freelance Management System, which manages freelance and directly sourced talent.
An Applicant Tracking System sits at the center of the recruiting workflow, giving hiring teams a single system of record for every candidate applying to an open role. Instead of managing applicants across spreadsheets, inboxes, and disconnected tools, recruiters run the entire funnel inside the ATS.
A typical ATS moves candidates through a structured sequence of stages:
Because it centralizes this data, an ATS also supports compliance recordkeeping, reporting on metrics like time-to-hire and cost-per-hire, and a cleaner candidate experience.
Most enterprise-grade Applicant Tracking Systems share a common set of capabilities designed to make permanent hiring faster and more consistent.

A Vendor Management System (VMS) manages staffing suppliers and contract labor, and a Freelance Management System (FMS) manages freelance and directly sourced talent. Many enterprises run all three because no single legacy tool covers the full workforce.
| Feature | ATS | VMS | FMS |
|---|---|---|---|
| Primary worker type | Permanent employees (W-2) | Agency-supplied contingent labor | Freelancers and direct talent |
| Core job | Post, screen, hire | Manage suppliers and spend | Source, manage, and pay freelancers |
| Feeds into | HRIS / onboarding | Procurement / AP | Direct sourcing and payments |
| Compliance focus | EEO, employment | Supplier and rate governance | Classification, EoR/AoR |
For enterprises modernizing their tooling, understanding these boundaries matters. Our guide on why legacy VMS platforms slow down contingent hiring explores where these systems fall short for the flexible workforce.
An ATS is essential for permanent hiring, but it was never designed for the contingent workforce of freelancers, contractors, and on-demand experts that enterprises increasingly rely on. That is exactly the gap WorkGenius closes.
WorkGenius is an AI-powered platform that combines AI matching with expert human recruiters to source, classify, onboard, manage, and pay contingent talent from one system. Where an ATS feeds employees into an HRIS, WorkGenius handles the parts an ATS does not: direct sourcing and talent pools that reduce agency markup, plus Employer of Record and Agent of Record compliance built in. It also integrates with SAP, Workday, Fieldglass, and Beeline, so it complements your existing recruiting and HR stack rather than replacing it. The result is one platform for the flexible workforce, running alongside your ATS for permanent hiring.
An ATS is used to manage the hiring process for open roles. It posts jobs, collects and parses applications and resumes, screens and ranks candidates, schedules interviews, and moves applicants through defined stages to an offer. It is primarily built for permanent, W-2 employee hiring and typically feeds new hires into an HRIS.
An ATS manages the hiring of permanent employees, while a Vendor Management System (VMS) manages staffing suppliers and the contingent workforce, including rates, requisitions, and supplier spend. They serve different populations, so many enterprises run both alongside a Freelance Management System for direct talent.
Generally no. An ATS is designed for permanent employee hiring and does not handle freelancer classification, direct sourcing, or contractor payments. Those functions belong to a Freelance Management System or a platform like WorkGenius that includes EoR and Agent of Record compliance for contingent workers.
An ATS usually acts as the front end of the hiring stack. Once a candidate is hired, their data is passed to an HRIS for onboarding, payroll, and ongoing employee records. Modern systems integrate through APIs so candidate and employee data flows without manual re-entry.
Yes, if you employ contingent talent. An ATS covers permanent hiring only. To manage contract and freelance workers, you need a VMS, a Freelance Management System, or a unified platform like WorkGenius that lets you source, classify, onboard, manage, and pay flexible talent while integrating with SAP, Workday, Fieldglass, and Beeline.
