we have a food retail shop with more than 300 products. We need a mobile app similar to Lalakart. You can download Lalakart app on your phone from google play store and check it. We need exactly similar kind of app but with different design. We need a backend to upload our products in different categories. You have to integrate [url removed, login to view] payment gateway for accepting payments. Let me know if it is possible to do and how much it will cost. Remember it will be a mobile application and not web.
