The ease of use! It's super easy to pick up and learn how things work in PMGCT. I've been able to do my job as an estimator without having previous experience using any estimation software. Sometimes it can be frustrating when there are too many options that you don't know what they all mean or do, but once you figure out what each option does or doesn't do (and you're willing to ask!) you'll have no problem learning everything about this program. If you're looking for a basic estimating tool that will help organize your jobs/projects then PMGT should definitely give it a try. We needed something simple that would allow us to keep track of our projects and do cost analysis without taking over half a day per project just to get started. This has helped solve those problems and also allowed me to spend more time working on other tasks.
