What it does
Sling by Toast manages staff schedules, communication and time records. Teams can distinguish recurring unavailability from leave for particular dates and send changes in availability through a manager's approval.
Use unavailability for a repeating constraint such as a class timetable. It can repeat every one to four weeks and have an end date. Time off covers particular full or partial days and does not repeat.
On Premium or Business, an administrator can enable approval in Dashboard → Settings → Schedule. Proposed changes arrive on the dashboard in yellow; review them and approve or deny. An approved set cannot be edited by the employee. They must submit another request, with the option to copy the previous set. Managers and administrators can also adjust it on their behalf.
Choose a scheduling plan
| Plan | USD per user/month | Main additions |
|---|---|---|
| Free | No charge, up to 30 users | Scheduling, time-off requests and private messages |
| Premium | 2 monthly; 1.70 with annual payment | Mobile time tracking, labor costs and group messages |
| Business | 4 monthly; 3.40 with annual payment | Shared-device time clock, wage reports and paid leave management |
The evaluation lasts 15 days. An administrator creates the company account with email and password or Google, then verifies their email before completing setup.
