Once the Professional version of Fluida has been activated, if you're an administrator, log into the app from your smartphone and follow these few steps:
Access the "Company" menu from the homepage
Activate the Clock in
Now you just need to enable your coworkers to clock in. In order to do this, you'll have to access each and every account via the "Users" menu: here you'll find all the clock in settings, right at the end of the screen.
