This document proposes developing an iPhone application for Dun & Bradstreet to help build their brand, promote their services to potential clients, and provide an additional service for existing clients. The app would allow users to access Dun & Bradstreet's database and corporate information after logging in. Developing the app would cost 50% upfront, with the remaining 50% due after design is complete. Upon approval, the design team would create initial concept designs within 10 business days.
