--------------------------------------------------------ABSTRACT-----------------------------------------------------------The concern of many organisations is to minimize the total time consumption taken for purchasing and billing. Through the analysis of customer behaviour, accurate profiles are being generated by specifying needs and interest and allowing organisation to give customers what they want it, when they want, leading to a better customer satisfaction thereby keeping them to come back for more. To improve the business performance of an organisation we need to automate the right offers to the right person at the right time. Our project provides the unique id for each registered customer. Based on registration the individual can start their shopping. After purchasing the product, they can scan the products using mobile application and the concerned bill for the particular customer will be intimated to the retailer, the number of products purchased will be checked and cash is paid. It reviews the status of products availability and it notifies to the retailer if it reaches concerned limit. This project provides the brief view of business liabilities to the retailers using apriori algorithm. This project will help the customer to purchase the products through online. Online shopping will also be useful for analysing the customer's previous shopping history.
