Ecommerce Mobile App Builder manages multi store apps by using a shared backend with separate store settings. Each store has its own products, prices, themes, and language options while running on the same app framework. Admins switch between stores from one panel to manage catalogs and orders. Ecommerce Mobile App Builder also supports store wise payments, taxes, and shipping rules. Central updates apply across stores, saving time. This setup helps brands run multiple stores smoothly, reduce costs, and keep a consistent app experience while scaling operations easily.
