Need a mobile application which can be installed either Apple or android. The app must be able to use over web based environment (later onwards) you must think whether the app can be transformed into webspace later without an additional cost before you start. The app is all about managing activities related to tea green leaf buying and selling them to tea factories. App user is a dealer who buy green tea leaf from small holders and then supply the leaf to factories. He is doing an intermediate business. The dealer daily collets leaf. While collection they usually write the gross weight of green leaf and then deduct some weights according to leaf condition. Then they transfer leaf to factories by their Lorries and same kind of weighing happening at the factory gate. Dealer should be able to add above details of their suppliers daily and details of green leaf they supplied to factory daily. Meantime a dealer has an inventory. Such as fertilizer, tea stocks, rice etc which are to be delivered to their suppliers. Once a dealer is installed the app, he might be able to ask their suppliers to install the same app and register as a gran leaf supplier to him free of charge with the use of OTP generated from the system to link dealers database. Once a supplier registered, he might be able to see all the green leaf he supplied and all the items (fertilizer,rice) he have taken so far including advance money taken. Every moth end the dealer should be able to add a green leaf price to the system. He can enter multiple values to the system for different qualities of green leaf he have entertained throughout the month. During the green leaf intake he must be able to select which category leaf he is taken. He should be able to move green leaf of particular supplier from category A to category B and wise versa as required even after few days. End of month he should be able to print bills to their suppliers. The app should be developed in several stages.
