We are using it for our sales team to send out quotes via email or PDFs which they can then open in their office software of choice (Outlook). The interface has been very easy to use with no training required! I have not found anything that we dislike yet but there isn't much as well so far either. It's great if you want your employees working from home since all documents sent through this application will be stored online instead of requiring them to print something off at work each day. This saves time/effort by reducing paper waste especially when sending large files back & forth between clients' offices. Also reduces cost associated wtih printing multiple copies throughout business days - just one copy saved per file received /sent eliminates tons of wasted ink cartridges over months across many users!! Benefits include reduced costs due to less printer usage + increased productivity overall because everyone works.
