Peapod: Fresh Grocery & Fast Food Delivery Mobile App

The client ran a local grocery and food business serving a residential area but had no digital ordering system. All orders came through phone calls, with no way to show live inventory, confirm availability, or collect payment upfront. Managing grocery and food orders simultaneously through calls was chaotic, especially during peak hours, and frequently led to out-of-stock disappointments after orders were already placed.

Key pain points:
- No app or online ordering — 100% phone-based with no scalability
- Inventory shown to customers was often inaccurate — items ordered were sometimes unavailable
- No online payment option — cash on delivery only, creating collection and reconciliation issues
- Customers had no order tracking — constant "where is my order?" calls to the team
- Managing grocery and food orders in the same call queue created operational bottlenecks

We built Peapod as a fast, reliable delivery app that digitizes the full order lifecycle — from browsing to payment to doorstep delivery — for both grocery and food categories.

Core features delivered:
- Dual-Category Ordering — grocery (vegetables, fruits, essentials) and fast food available in one app with a clear category switcher and a unified cart
- Real-Time Inventory — stock levels updated live so customers only see what's actually available at time of ordering
- Smart Product Browsing — search, category filters, and curated featured sections for quick discovery of daily items
- Secure Payments — Razorpay integration supporting UPI, cards, net banking, and wallets with instant payment confirmation
- Order Tracking — live order status updates from confirmed to dispatched to delivered, with estimated delivery time
- Push Notifications — order confirmation, dispatch alerts, and promotional notifications via Firebase
- Admin & Delivery Panel — backend dashboard for managing inventory, accepting orders, assigning deliveries, and tracking active orders

1. Real-Time Inventory Accuracy
The biggest operational problem was showing customers items that were actually out of stock. We built a live inventory sync system where stock levels update the moment an order is placed — and added a buffer threshold that marks items as unavailable before they physically run out, preventing last-minute cancellations that frustrate customers.

2. Unified Cart Across Two Different Order Types
Grocery and fast food have different pricing logic, preparation times, and delivery handling. A single cart that could hold both required careful backend design — we built a cart model that tracked items by category, calculated estimated delivery times separately for each, and presented a clean combined summary at checkout without confusing the customer.

3. Performance on Low-End Android Devices
Delivery apps are heavily used on budget Android devices. We optimized the React Native build specifically for lower-spec devices — lazy loading product images, minimizing re-renders on the cart and inventory screens, and reducing app bundle size — ensuring smooth performance across the full range of devices the target audience uses.

Phase 1 — Flow Design & Architecture (1 Week)
Mapped the complete order flow for both grocery and food categories. Defined the inventory data model, cart logic for mixed orders, and the delivery status state machine.

Phase 2 — UI/UX Design (2 Weeks)
Designed all app screens — onboarding, home feed, category pages, product detail, cart, checkout, payment, and order tracking. Focused on speed and simplicity — the primary use case is repeat daily ordering, so the UI was optimized for familiar, fast navigation.

Phase 3 — App Development (5 Weeks)
Built with React Native for iOS and Android. Implemented real-time inventory sync, dual-category cart, Razorpay payment flow, Firebase push notifications, and live order tracking. Built the admin and delivery panel in parallel.

Phase 4 — Testing & Launch (2 Weeks)
Tested all payment flows including edge cases — failed payments, partial refunds, and COD fallback. Load tested inventory sync under simultaneous orders. Beta tested with 30 users before full launch on App Store and Google Play.
