I just wanted to build a simple ecommerce website & Ios+android App, which allow
1) end users to register, store payment details, make payments (card +popular app in india), order the item through app before 10pm, schedule the delivery, and alert when delivered the items as well as full report about history of orders and payments...
2) Delivery boy app which allow to map the delivery items to delivery boys and automatically alert for delivery as well as completed the delivery notification when done
3) Admin portal, for managing the items, suppliers,stocks, users, delivery boys etc and reporting
Stock should be live update or offline update or allow to put the limit, 1000 items, if not in stock or already ordered 1000 then no more orders but put in pending for order and alert when stock available.
