The project was an attempt to understand various problems related to the productivity of small food stalls and how smart phones can help to mitigate them. The project aims to help the shop owners to manage orders and credit accounts of customers and reduce errors in overall transactions. Various stalls were studied to understand the daily scenario, their job and to identify the pain points. Several design ideas were generated targeting these problem areas. The major challenges faced while designing the solution was the adoption by shopkeepers in using the application, whether they will be able to manage credits and their daily transactions with customers. Will the record keeping help them in increasing the productivity of shops. Final concept named ‘Munshee’ was developed as a mobile application that helps the shop owners to have a track of the multiple orders, creates sharable invoices, accounting and insights of daily transactions. It also proposed a system that helped resolve the awkward scenario between customers and shop owners due to credits taken by customers. The application enables an intuitive way of billing for shop owners and management of credit. The debtor is notified by the system upon exceeding the credit limit. The shop owner can see the summary of the day easily. It shows revenue made through each food items, amount in credit and amount that should be with the owner. An evaluation was conducted in 5 shops with the prototype of the final solution. The goal of the evaluation was to find any issues related to the usability of the application to determine if the proposed solution can help in checking their logs of their overall sales of the shop and management of credit accounts
