I have been using sage talk for a year now, it is very easy to navigate through multiple accounts and also helps in customer management, scheduling appointments, billing etc.
The best part of sage talk is that you can create your own customisable bots which other people can use too! Sometimes my conversations with the bot stop working randomly i have to restart to get back into the flow, this has happened once or twice when trying to schedule an appointment with Sage Talk but not often enough to make me want to switch services. Some features are missing like calling banks or insurance companies directly from the platform so we still need separate apps to do those things. We had an issue with Sage Talk service provider and they helped us resolve our issues quickly and professionally.
