Follow Up communication CRM

How CRM handle the follow up communication Between sales person and customer

There is a way to specify the next follow-up date for a contact person of a customer. ERPNext will then be able to create a TODO task for a sales manager to do the actual follow-up

Thanks for your quick response

if you mean the next contact section in the opportunity page is only make an event in the sales person calendar not TODO task even so how can use TODO task to manage the communication between SP and Customer and how sales manager can follow up this communication

Thanks again

You get that through Comments

The comments is not professional way to manage communication

Has someone got a solution for this problem?
