You get the call the next day from your customer. Their security alarms went off last night. Your customer thinks your employees set it off. Do you have the proof you need when you say your employees were already gone by that time? If not, you may have to pay for the police run that was made to check the alarm status at your customer’s site. Has this happened to you?   This could get costly$$$.  When you use telephone timekeeping you know exactly when your employees clock in and when they clock out.  You have the proof!  (And unless those employees work at a bank and are planning the bank heist, you know they left the premises when they clocked out.  Who sticks around a worksite when they are not getting paid?)  This does not have to happen to you again!
