By default, Sling will create a location matching your company name when you create your account.
To add another location, go to Dashboard > Locations. Click the Add location button.
A form will appear where you can name the location, set an address, select the time zone, add employees, and more. Note that Timeclock settings and Projected sales will only appear if you have subscribed to Premium. The timeclock settings also require that you have enabled the IP address option for the Time Clock.
Click Save and you are all set to schedule for your additional location.
From the mobile app:
Tap the More icon, then choose Locations.
Tap the + icon at the top right.
Fill in all the details for your location, then tap Save.
You're all set to schedule for your new location.
