WhatsApp business account is called WhatsApp group. All they do with it is to share information that are strictly related to the nature of business. And this is done after creating the group, and sending invites to people for them to join, or creating a link that would allow anyone to join using the link. Often times, the link can be shared on other platforms which apparently would connect anyone who clicks on it to the WhatsApp group chat.
WhatsApp business account is significantly different from the normal account, as it's not meant for chatting between individuals on the group, but to promote and advertise what the business is all about. Unlike the normal account where one can chat conveniently with another fellow who is his/her friend.
