My company started using OnTime over three years ago. Being in the business it is hard to find programs that cater to all needs from dispatching to billing. OnTime is the best program we could find to fill our niche , allow us to operate our systems with full optics and allow custom made "hook-ups" to our other software that we are allowed to run in conjunction.
