There should be two apps, one for customer and one for our parking partner and Web Admin Panel should be connected to Web Admin Panel. There should be an eWallet on our app which should be connected to our payment gateway. Parking partner will have feature to scan the QR code on customer app to alot the parking and once the scan is done, payment should be deducted from eWallet. After one parking slot is booked, it should be converted to unavailable slot for other customers with different color on their app like movie ticket booking. Customer should be able to see number of total parking slots, available slots, booked slots, reserve slots on their app in any parking area. You will have to create an automatic payment debit credit in the ewallet from the app, where customers can link with their Paytm or other eWallets. So that money can be deducted from that wallet only and customers shud have the features to recharge their ewallet. Signup should be done using Otp authentication. One mobile number can be registered with one account only. There should be push notification feature in the app. There should be an option for admin to download their complete sales reports of all of the partners in excel sheet format datewise, day wise, yearwise or custom date wise. There should be customer support feature. Customer can chat with admin anytime. After booking any parking, customer should get an invoice on their mail and orders section in the app. After an order is made or an cancellation, customer should get sms confirmation and app notification also. Its a prepaid service, once any parking booking order is attempted, it should be confirmed only by making payment. If any parking is cancelled by customer then no refund will be given. But if booking is failed then automatic refund should be credited in their ewallet. There should be an option for shopkeepers in any mall to give their ads or discount coupons on sliding banner. Those discount coupons issued by our partners should be redeemed on our app for providing free parkings. There should be an option of refferal codes sharing, when any user refer our app to other user, then one code should go to other user with our app link, when other user will open our link and download the app and book any parking then first parking charges will be free for that user for upto 50 INR.
