1. to make it multi vendors, vendors can be added in the backend
2. Product category and products under each vendor, as of now product category and products are already in the system.
3. area based hyperlocal so that users can only see those vendors/store in the app in a certain radius of users current location
4. Delivery charge depending upon distance/ quantity wise
