The eCommerce mobile app development cost depends on factors like app complexity, features, design, and platform. A basic app with essential features, such as product listings, shopping carts, and payment gateways, ranges from $10,000 to $30,000. Advanced apps with custom designs, AI-driven recommendations, and AR functionality can cost $50,000 to $150,000 or more. The development team’s location also impacts costs, with rates in North America being higher than in Asia. Ongoing expenses like maintenance and updates add to the total cost. Defining clear requirements and consulting experts helps estimate the eCommerce mobile app development cost accurately.
