Cloud sales tracking

Hi! I need to build an appication for (iOS) that is used by businesses to track sales online. When clients (Head of sales) access the app, they can see total budget fulfillment, budget fulfillment of each sales manager, how much of each product is sold. Sales managers will access the app daily to input planned sales data/ activity. Head of sales will be able to check the sales online. 1. Easy to use interface. Modern and smooth design. 2. Secure login and data storage 3. Data input 4. Export/ import to excel, powerpoint The informtaion from which date is pulled and edited can be stored securely on a server. See attached preview.
