All us small business owners need to watch our spending on overhead items. I recently used a great service which I have to rave about... Validas (www.myvalidas.com). You submit your cell phone bills and they analyze them and suggest changes in plans and coverage to save you $$. They also suggest alternate carriers and model out the potential savings based upon your bills and use. It's quite economical. Very helpful especially when you have 8 cell phones with greatly differing usage patterns
