  • “Going from 10 employees to 90 this year has been a whirlwind to say the least. We never could have made this transition without Sling’s time tracking and scheduling tools. With so much going on, I can’t tell you how grateful we are to have one less thing to manage ourselves. Thanks for all your help!”
