I like that you can use this system with your own clients or even other companies! You have access from anywhere at anytime, so no more using my phone while driving home just because i'm not near an internet connection!! Sometimes there are issues when uploading documents but overall its great as long as they keep working out all of these problems.
So far we haven't had any major setbacks yet though our current client has been very helpful about keeping us informed whenever something comes up (such as them having some new software update). We've solved many questions regarding HR management over time by being able to give feedback via email/phone calls etc instead of sending emails back & forth which takes too much effort sometimes.
