I like that it gives me options on how to communicate with my clients using different methods such as phone or internet etc. I also like how you can send documents from your computer directly into this application saving time especially when sending large files over the internet. Sometimes I have had problems trying to delete certain conversations so sometimes I cannot find something easily if at all. There are some features which would be nice however they could not do much about them because there were no updates since their creation. So basically use these applications because nothing else was made to fit within your needs. Sending invoices quicker through emails than going out via mailman service. Also being able to keep track of things easier because everything is right here!
