Traditional retail billing relies on manually scanning products one by one, making checkout time-consuming and contributing to long queues during busy hours. Manual processes can also introduce billing errors and provide limited real-time visibility into inventory and sales performance. Retailers therefore need a faster and more automated approach to billing and store management. NigaahAI addresses this gap by using AI and computer vision to identify products through a mobile camera, automatically add them to the cart, generate bills, update inventory, and provide real-time sales and inventory management.
