Hello, I will build your earnings and transactions app — secure payment processing, transaction history, QR code scanning, and the cashback/referral engine — deployed to both iOS and Android from a single Flutter codebase. For the cashback system, I will design a rules engine that lets you configure percentage tiers per transaction type or spending threshold without requiring an app update. This keeps your reward strategy flexible as you scale and test what drives retention — all controlled from an admin panel. Questions: 1) Which payment gateway do you prefer — Stripe, Razorpay, or another provider — and do you need wallet-to-wallet transfers between users? 2) For referrals, should bonuses trigger on signup alone, or only after the referred user completes their first transaction? Looking forward to talking through the details. Kamran

Hi there, I will build on Flutter for iOS and Android: UPI payments via aggregator API, transaction history, QR scan-to-pay (UPI Intent on Android, deep links on iOS), cashback ledger, and referral tracking with device-level abuse checks. The constraint this brief needs to address: cashback is regulated in India. Holding user balances requires an RBI PPI license (12-18 months) or partnership with a licensed aggregator (Razorpay, Cashfree, PhonePe Indus). The app connects to the aggregator's wallet API rather than maintain its own ledger. Questions: 1) Existing aggregator partnership, or in scope? 2) Cashback funded from margin, or sponsored by merchants? 3) Target launch in how many weeks? Looking forward to talking through the details. Best regards, Faizan

Most cashback and referral apps fail when transaction volumes spike or when payment reconciliation gets messy between QR scans, backend processing, and wallet updates. Built a Flutter fintech app with UPI + QR scanning that handled 50K daily transactions. Also shipped a referral engine with multi-tier cashback logic and fraud detection. Are you planning instant cashback credit after each transaction, or batched payouts at intervals, and does the referral bonus stack with transaction cashback or stay separate?
