A simple address book is not sufficient anymore these days.
The CRM module of System 5 stores your contacts in a hierarchical structure (companies with departments and persons). Various user rights ensure an accurate state of your vital client data.
A variety of built-in features help you to gain a complete view of your customer records. System 5 gives you instant access to the complete communication between you and your customer, if needed, years back. The comment section, the customer related attachments and the phone integration make this tool complete.
