Sling

Sling is a specialized scheduling and workforce management platform built to handle the complexities of shift-based work. You can create clear, conflict-free schedules in minutes using drag-and-drop tools and templates that account for employee availability and time-off requests. It helps you eliminate the chaos of paper schedules and endless group texts by centralizing all shift communication and coordination in one mobile-friendly hub.

Beyond simple scheduling, you can track actual hours worked with a built-in time clock and monitor labor costs in real-time to stay within your budget. The platform is designed for businesses of all sizes, from single-location cafes to large enterprise retail chains. By using Sling, you reduce absenteeism, prevent double-booking, and ensure your team always knows exactly when and where they are supposed to work.
