The CSI Vendor Relationship Program has two main benefits, one for the Vendor (that’s you), and two for our existing and future Clients. By becoming a Premier Vendor in our Vendor Relationship Program, your organization will be promoted to an untapped reservoir of potential customers. Many vendors currently accepting the CSI Virtual MasterCard Program request we refer and enroll them with existing and new Clients, allowing the vendor to build stronger relationships and increase revenue by acceptance of the CSI Virtual MasterCard Program.
