Women-owned Micro, Small, and Medium Enterprises (MSMEs) play an important role in strengthening household and local economies. However, many women entrepreneurs still face challenges in managing business operations, particularly in digital inventory recording, production cost calculation, and the utilization of digital marketing. This community engagement program aims to empower women-owned MSMEs through the development and implementation of a smartphone-based application for inventory management and digital marketing within the Red and White Cooperative ecosystem. The program was conducted with members of IPEMI PC Bojongsari through participatory training, hands-on application practice, mentoring, and evaluation. The activities introduced Smart-POS UMKM to support digital inventory recording, sales transactions, cost management, and business reporting, complemented by training on production cost and Cost of Goods Sold (COGS) calculation and data-driven digital marketing. The program emphasizes the integration of inventory and sales data to support pricing, promotional strategies, and business decision-making. Through this integrated approach, participants are expected to improve their digital financial literacy, operational efficiency, inventory management, pricing accuracy, and digital marketing capabilities. The program also strengthens the role of the Red and White Cooperative as a community-based ecosystem for supporting women-owned MSMEs through digital innovation. This initiative contributes to the achievement of Sustainable Development Goal (SDG) 5 (Gender Equality), SDG 8 (Decent Work and Economic Growth), and SDG 9 (Industry, Innovation, and Infrastructure).
