Why it comes up: UKG Dimensions pairs enterprise WFM with a wider HCM and payroll suite from the same vendor.
Stands out: AI-powered scheduling that uses demand history, skills, certifications, preferences, and labor budgets, plus time, accruals, leave, and analytics as separately licensed modules.
Watch out: This is not an SMB shift app. Timekeeping, scheduling, forecasting, and analytics are PEPM modules with implementation typically in the tens to hundreds of thousands. UKG Ready is the smaller-company SKU.
Best for
- Large hourly employers that need AI scheduling, forecasting, and FLSA/ACA-style time rules
- Health systems, manufacturers, and retailers already in the UKG stack
- Operations teams replacing Kronos Workforce Central-class timekeeping

Why it comes up: Deputy suits smaller and mid-size hourly teams that want quick self-serve setup over custom ML forecasting.
Stands out: A public $5/user/month Lite seat that already covers basic rosters, clocks, and labor-law rules, with payroll connectors in the same conversation.
Watch out: Auto-scheduling, biometrics, and SSO sit on Core or Pro. Payroll via Paycor is $8/user/month plus a $49 monthly base.
Best for
- Multi-location hourly employers
- Hospitality, retail, and healthcare rosters
- Teams that need Fair Workweek-style rules

Why it comes up: Celayix focuses on enterprise shift scheduling for complex operations rather than retail-style demand forecasting.
Stands out: The vendor pricing page prints size bands: Small Team up to 100 employees at $400 to $800/mo, Medium up to 1,000 at $1k to $8k/mo, Enterprise contact.
Watch out: Every band still goes through Get a Quote. A 25-employee minimum applies on an annual term, and implementation is scoped separately.
Best for
- Mid-market and enterprise ops with rules-based shift scheduling, not a cafe rota
- Multi-location employers that need time, attendance, and payroll inputs in one WFM
- Security, events, and healthcare desks that already run complex qualifications

Why it comes up: When I Work is a lighter scheduler and time clock for single or few-location hourly teams.
Stands out: A public $2.50/user/month seat for single-location scheduling, with payroll and POS connectors on paid plans.
Watch out: Multi-location work jumps to Pro at $5/user/month. Premium at $8 is the scaled tier. This is not an ATS.
Best for
- Single-location hourly employers
- Small retail, food, and healthcare teams
- Managers who want clocks next to the roster
