What are the differences between Sleekflow and Callbell?

Sleekflow is a tool designed for large companies: this means that its price is quite high as this tool offers a multitude of options and functions for all needs. However, being so extensive, it tends to become particularly complex to manage. Onboarding salesmen is difficult, and sometimes support strays a lot, as well as being a fairly expensive tool.

Unlike Callbell which is cheaper. The customer assistant offered by Sleekflow is not particularly excellent as it is aimed at customers who own large companies, unlike Callbell which is dedicated to small and medium sized companies. Likewise, Callbell offers a multi-agent omnichannel platform to manage all your conversations. The platform is very simple and easy to use, onboarding does not take a lot of time. The biggest advantage of Callbell is the support, as its agents are always willing and ready to help their users at any time and for any request.
