WOW, mcracing summed up the entire discussion in one post.

GPS is a valuable tool if used correctly. You will have some problems upon implementation but in the long run it will pay off and techs who do what they are suppossed to be doing can practically ignore the GPS all together. Customer retention and customer service are key and any tool that helps with these two important factors of a service business is no longer an option but absolutely essential equipment.

I believe mcracing is genuine because of what he said about being a sales person. I was in outside sales for new trucks for some time and I can say this: Any sales person who is pulling their weight is not working 6 or 7 hours a day, they are working long hard hours, 10 or 12 hours sometimes. And remember, this is for commission, not hourly pay, no overtime and you need to "cold call" constantly. You will definately gain new respect for sales people once you actually do the job, but that being said there is no better pay off than selling a new truck to a new customer and beating out 4 or 5 competitors and you weren't the low price.

This has been a great, informative discussion with loads of great posts so far.
