As far as bang for the buck you will not beat RealTrack. I've had other companies call me about GPS and when I tell them I use RealTrack they have little more to say. $18 a month is very little to pay and the best thing is there is no contract. If you park a truck in the off season you could stop the service if you wanted. You can print out history reports months later that show exactly where your truck went. It can tell you the speed of the truck, the address the truck was at, and I think you can even set boundaries where you will be notified if the truck leaves an allowed work area.. The truck functions it will monitor are the key position. It will tell you on, off, or idle. Idle is good because you will know if your guys are enjoying the AC when they should be working. I hope someday video monitoring becomes cheap. It would be great to have a camera with a wide angle lens to record the work being done at properties from a street perspective. If you suspect waste or inefficiencies it would give you a birds eye view of where you may be losing money. Plus if you get ripped off you might get to see who did it. Like I've said in the past even if you only run one crew GPS is too cheap not to be using it. You will have records to prove you were at properties and you will know the exact time spent at those properties to know if your on budget. It also works well to keep track of lunch breaks to see if guy are writing precise times or just throwing ink on the time sheet at the end of the day. If GPS shows the truck is in motion during the lunch break you will know something is up. Even good employees tend to fudge things sometimes. The longer people work for you the greater the chance is they will get complacent and develop time wasting habits that will waste your money. Having blind trust in your employees can be costly. From poorly designed trailer setups to mediocre employees the amount of waste I see when I look at other companies at job sites is just amazing. They are throwing money away hand over fist and have no idea they are doing it. I would dare to say anyone who is not using GPS and can't rationalize it probably has a lot of other issues being over looked as well.
