CRM - customer management program

We need a customer management program that is available online.

There are certain functions that absolutely must be covered. These are as follows:

Two-Factor Authentication (2FA)
Chat
Connection to Dropbox
Export options
Reminder Company
Reminder customer
ToDo-List
Connection to Google Calendar
News
Customer management
Sales-Channel/Pipeline
Rights management
Facebook integration
Invoicing
Expense management by location
Opening hours and country limitation of the system
Automatic document creation
Abuse report
Time & Tasks tracking employees

The list is not exhaustive. We should have the possibility to add other functions later.

I ask you to apply for the project only if you have done something like this before.

We would like to work only with someone who does the work himself. WE DON'T WANT TO TALK TO SOMEONE AND THEY GIVE THE WORK TO SOMEONE ELSE.
