Sling

Sling is a specialized scheduling and workforce management platform built specifically for businesses with shift-based employees. You can move away from messy spreadsheets and paper schedules by using a drag-and-drop interface that accounts for employee availability, time-off requests, and labor costs in real-time. It helps you eliminate scheduling conflicts and ensures you always have the right people on the clock.

Beyond simple scheduling, you can track attendance with a built-in time clock, manage tasks, and communicate with your entire team through integrated messaging. Whether you run a single restaurant or manage multiple retail locations, the platform helps you stay under budget by alerting you to potential overtime. It simplifies the entire lifecycle of shift management from the moment you post a schedule to the final payroll export.

The platform simplifies your administrative workload by automatically calculating regular hours, overtime, and holiday pay based on your specific rules. You can manage time-off requests, view real-time attendance dashboards, and export data directly to popular payroll providers. It is designed to scale with your business, supporting unlimited departments and providing tools to help you stay compliant with labor laws.
