I love that it allows our customers to create an account with us by using their Facebook or Google accounts instead if having them sign up from scratch! It also helps keep track how much each person has spent while they are at work so we can better bill out hours later when billing clients after leaving the store open during lunch time etc..
This software isn't very intuitive sometimes but once you figure things like "where do i click" its easy enought o use again :) We have created customizations which makes this even easier than just going through all those steps everytime someone logs onto there computer/phone (customizing email signatures).
