The ability to pull in data from multiple sources and then create your own reports and dashboards.The ability to use all of the available features without having to pay for more modules. The fact that it's a cloud-based software. It's not as easy to get started with as some other platforms out there. There are a lot of different modules that can be used independently or in conjunction with each other. However, if you don't know how to use them properly, you could end up spending a lot of time trying to figure things out. I am using shelf to monitor our call center performance. We have been able to identify trends and problems faster than before.
