Order Management System For Dicsis

We are a FMCG Company called Dicsis which manufactures 4 different kinds of products i.e. chocolates, health drink, biscuits and shampoo. We operate in almost all parts of India. Our sales team consists of 500 people who visits a number of retail outlets. We are planning to give PDAs to our sales team so that they can know about the inventory from any point at anytime. When they log in they should get information about the exact inventory level so that it wil be easy for them to place order. Both during execution and cancellation of order they should be able to update the same. This information about order picked and order cancelled should also be accessed from the central depo as it will be easy for the depo to manage their warehouse.
