Sling vs When I Work: Which Is Right for Your Team in 2026?

Sling and When I Work are both hourly workforce scheduling tools for small businesses, but they have meaningfully different pricing strategies and feature sets. Sling's free plan is more generous than most — it covers unlimited employees and unlimited locations with basic scheduling and communication, making it competitive even against Homebase. When I Work has no free tier but offers more polished scheduling automation, particularly auto-scheduling and time clock features. The choice often comes down to price sensitivity versus scheduling workflow polish.

Sling's free tier is genuinely broad: unlimited users, unlimited locations, basic scheduling, task management, and team newsfeed. This is the most expansive free offering in the scheduling tool category. Premium plans add time clock, overtime tracking, labor cost management, and reports — starting around $1.70/user/month. When I Work charges from $2.50/user/month with no free tier. For budget-constrained operations, Sling's free plan can cover core scheduling needs indefinitely before any paid upgrade.

1. 1Sling Free: unlimited users + locations, basic scheduling and communication
2. 2Sling Premium: ~$1.70/user/month — time clock, overtime, labor reports
3. 3Sling Business: ~$3.40/user/month — kiosk, POS integrations, labor budgeting
4. 4When I Work Scheduling: ~$2.50/user/month
5. 5When I Work Scheduling + Attendance: ~$5/user/month
6. 6When I Work Advanced: custom pricing

When I Work is generally regarded as having a more refined scheduling UI — auto-scheduling is faster to configure, templates are easy to reuse, and the shift swap approval workflow is clean. Sling's scheduling interface is functional but less polished; auto-scheduling requires more manual review. For managers building complex rotating schedules or who want to spend less time on schedule creation each week, When I Work's interface saves meaningful time. For managers comfortable with manual scheduling who prioritize cost, Sling's interface is sufficient.

Sling includes time clock on its paid Premium plan, with GPS-based clock-in and kiosk mode on Business tier. When I Work includes time tracking with GPS and photo check-in on its Scheduling + Attendance plan. Both handle the core use case. Sling's kiosk and POS integrations on Business tier align with restaurant and retail environments. When I Work's time clock is available at a lower tier, making it cheaper if time tracking is a required feature rather than optional.

• Sling: free plan covers unlimited users and locations — rare in the category
• Sling: labor cost and budget tracking on Business tier
• Sling: task management and newsfeed included free
• When I Work: more polished auto-scheduling with less manual cleanup
• When I Work: time clock available at lower price point per user
• When I Work: cleaner employee shift swap and approval workflows

Sling includes messaging, team newsfeed, and task management even on the free plan — a broad communication offering for no cost. When I Work also includes team messaging but without the task management layer. For managers who use the scheduling tool as a communication hub — posting updates, assigning tasks, and broadcasting policy changes — Sling's free communication features are a genuine advantage.

When I Work integrates with Gusto, QuickBooks Payroll, ADP, Paychex, and several POS systems. Sling's integration list is shorter — QuickBooks Time, some POS platforms — which can be limiting if your payroll system is less common. For teams running Gusto or ADP, When I Work's integrations are more battle-tested. Sling is still adding integrations but lags behind When I Work in breadth of payroll connections.
