The most valuable aspects of the solution include:

Live chat.  The live chat is so easy to customize. You can customize it with fonts, and brand colors, and you can use the logic to hide it for only logged-in users so they are the only ones that can access the live chat.

Hot mapping. Hot mapping is very vital for looking at having a unique URL for your knowledge base. It makes it so easy to add a DNS record and verification. 

Social media. Integrating with social media is pretty cool. You can use it to provide support from one place via different handles.

We like the mobile application, which allows us to provide a faster response to the customer. These days, customers are tech-savvy. They log a TT only after running several checks on their own because TT logging or calling CC is in itself a generic and time-consuming process. Hence, the availability of an Android and iOS app makes the response delivery faster. Also, it ensures the customer that someone is actually by their side, looking after their issue.
