The PrimeNet Time Bot can simplify your needs

Is a time and attendance tool that lets teams track their work duration, vacation, holidays and overtime easily. All you have to do is DM ex. @primenet_time_bot with your request for time off, or a simple ‘in’ and ‘out’ message to log your hours. The bot records time worked and time off, and even submits requests for approval straight to the relevant manager.
Many companies utilize Slack for inter communications. Why not take advantage of using it for time tracking too?
The convenience to clock in and out wherever you work.
