Building a food delivery app is one of the most complex mobile projects. You're not building one app - you're building three, plus a backend. Here's what that actually means.
The 4-Part Architecture
A proper food delivery platform consists of:
- Customer app (iOS + Android) - browse menus, order, track, pay, review
- Courier app (iOS + Android) - receive orders, navigate, confirm delivery
- Restaurant panel (web) - manage menu, accept/reject orders, set availability
- Admin dashboard (web) - analytics, disputes, user management, payouts
Skipping any of these creates operational bottlenecks. Start with all four in MVP form.
Core Features by Priority
Must-have for launch
- User auth (phone number + OTP, no email friction)
- Restaurant catalog with categories and search
- Cart and checkout
- Real-time order tracking (WebSocket + Google Maps)
- Push notifications at each status change
- Payment integration (card, wallet, cash)
- Order history
Phase 2
- Reviews and ratings
- Promo codes and loyalty points
- Multiple addresses
- Scheduled delivery
- In-app chat (customer ↔ restaurant, customer ↔ courier)
Phase 3
- Subscription (free delivery)
- Corporate accounts
- AI-powered recommendations
Real-time Tracking: The Technical Core
This is the hardest part to get right. You need:
- Courier app sending GPS location every 3 seconds via WebSocket
- Backend storing and broadcasting positions
- Customer app consuming the stream and updating map marker smoothly
Use Socket.io or Firebase Realtime Database for the location stream. Google Maps SDK on the client. Budget 2-3 weeks just for this feature.
Payment Integration
For international: Stripe (supports split payments to restaurants via Stripe Connect).
For CIS markets: Kaspi Pay (KZ), mBank/Optima (KG), ЮKassa (RU).
Always implement cash-on-delivery as fallback - it accounts for 30-50% of orders in emerging markets even with good payment infrastructure.
Tech Stack
| Layer | Technology |
|---|---|
| Mobile apps | Flutter |
| Backend API | Node.js + Express |
| Real-time | Socket.io |
| Database | PostgreSQL + Redis (caching) |
| Maps | Google Maps Platform |
| Push | Firebase Cloud Messaging |
| Infrastructure | Docker + VPS or AWS |
Cost Breakdown
| Package | What's included | Cost |
|---|---|---|
| Starter (1 restaurant) | All 4 parts, basic features | $4,000-8,000 |
| Business (multi-restaurant) | Full feature set | $8,000-18,000 |
| Platform (marketplace) | Aggregator model, vendor onboarding | $18,000-50,000 |
Timeline: 3-5 months for a proper MVP.
Common Mistakes
Building for one city from day one at aggregator scale. Start with one restaurant or one neighborhood, prove the model, then scale.
Underestimating the operations side. The app is 40% of the work. Courier recruitment, restaurant partnerships, and customer support are the other 60%.
Cheap real-time tracking. Polling every 30 seconds instead of WebSocket. Users will notice immediately.
