Is there a link between Simple CRM and Facebook, Twitter, Linkedin, Viadeo, etc?

Yes, Simple CRM is connected to social media via its CRM social module. There are two practical cases: either you already have the social coordinates of a contact person or a company and in this case, Simple CRM will allow you to see and analyze its social activity. Either Simple CRM will help you find this person on social media so you can then "monitor" them.
