I like that it is easy to use, can be customized for your business needs & very configurable! It's not perfect but we have been using this software since 2007 in our travel industry (airline) so there are some things you learn over time with any system out of the box.
But overall its great product if used correctly!! Nothing really specific other than just having all information centralized into one place has helped us tremendously when hiring new staff or doing payroll as well as keeping track of inventory/purchases etc.
