I need a simple, working mobile app of a mobile payment-collection system for my Set-Top Box business. The goal is to let customers record their payments, field workers confirm collections on-site, and give me an at-a-glance admin view of daily activity. Core features to build: • Customer module (iOS and Android): sign-up / log-in, submit a payment by UPI or cash, and tag the payment to a field worker via dropdown or QR. • Worker module: log-in, see today’s assigned customers, mark payments as verified, and filter their list by date, status, or customer. • Admin module: lightweight dashboard showing total collections (today and month-to-date), payments waiting for approval, and a quick view of each worker’s performance. Essentials I expect with delivery: • Mobile build for iOS and Android plus a minimal backend API and database schema. • Working QR scan flow wired to the payment record. • Basic in-app notification pop-ups for status changes (no email or SMS). • Clean, commented source code and deploy that. The scope is intentionally lean—just enough screens, endpoints, and logic to prove the concept end-to-end. If this pilot runs smoothly, I’ll reopen the project for extra refinements like browser access, richer analytics, and SMS alerts. We can also provide you the frontend files if required you can customize your backend accordingly.
