Although the use of WhatsApp has many benefits, the classic version has some obvious limitations. The first being the absence of a multiuser feature. WhatsApp (both in its normal and business version) cannot be used by multiple providers simultaneously, and it is difficult for the agent to supervise the process, since it would have no way to observe the speed and the quality of the answers provided by their suppliers.
These limitations are solved by platforms such as Callbell, created in order to allow a collaborative and efficient management of a single WhatsApp account.
