eCommerce App Development: Custom Mobile Commerce Beyond Shopify and BigCommerce

eCommerce app development covers custom mobile commerce applications built for businesses whose sales process, catalog structure, or customer experience requirements exceed what Shopify, BigCommerce, and WooCommerce mobile apps provide. The standard eCommerce platform mobile apps work for straightforward product catalogs with standard checkout flows, but they break down when the business needs custom product configurators that render in real time, complex B2B pricing with contract-specific rates and approval workflows, offline-capable ordering for field sales teams, AR product visualization, or native integrations with warehouse management and ERP systems that go beyond the platform's API limits. Custom eCommerce app development starts at $80,000 for a single-platform native app with standard catalog and checkout, and runs $150,000-$400,000 for complex B2B or omnichannel applications with custom integrations, offline capability, and multi-warehouse inventory visibility.
