It depends on what type of company your running...and if you own or lease your equipment...but with the right partner they can be really great. One of the main things is to have the right size telematics company for your fleet of assets. There are companies that are set up for small, medium and large asset fleets. I recommend getting a few quotes from a few companies and comparing the up front cost and ongoing monthly subscription fees. There's usually some really good regional companies. If you find the right partner, for a fair price you can get tons of insights on your assets, diagnostics and preventative maintenance, theft prevention, and location/utilization info.
