The study showed that most of small scale retailers have not yet embraced technology in their business with only 17% having implemented a computer-based system. The study proposes an application for accounting and management of inventory to be adopted by the small scale retailers in Kenya. The application enhances the accounting and inventory management processes of retail shops by countering the challenges of the traditional paper-based system which is used by most small scale retailers. The application assists retailers to manage kiosk’s products, stock and to review product sales. It has integrated a barcode system for easier tracking of the shops inventory. It has implemented the VMI system that allows suppliers to keep track of the product stock levels thus making the management of inventory more efficient and effective. The proposed solution was developed following the agile development life cycle which provides flexibility in reworking of the solution. The solution was built to have a front-end that was implemented as a mobile application and the back-end as a web application. The mobile application is used by the retailers to manage their shop and suppliers to keep track of inventory levels and the web application provides sales analytics and system administration.
