CRM stands for Customer Relationship Management. This is a section that can be used for company wide customer contact, from communicating with customers that have birthdays or anniversaries, or who have bought from a specific vendor or type of jewelry. Numerous filters are available to do targeted mailings or emails to customers that have spent more than x dollars during a time frame, or who had purchased from you in the past but haven't recently. Please see the Customer Tracking selection under Software Features to see the CRM screen.
