AI Restaurant Ordering Platform
A WhatsApp-native AI ordering system that lets customers browse menus, customise orders, and pay — all without leaving their chat app.
Overview
We designed and built an AI-powered ordering platform for a fast-casual restaurant group that wanted to reduce front-of-house pressure while improving customer experience.
The system integrates directly with WhatsApp Business API, allowing customers to send a message and receive an interactive menu. AI handles natural language understanding, so customers can say "I want the burger without onions and a Coke" and the system interprets and confirms the order accurately.
Payments are handled through a secure link sent in-chat. Orders flow directly into the kitchen display system, eliminating manual entry.
The client saw a 40% reduction in phone order handling time and a measurable uptick in average order value due to smart upsell suggestions built into the AI flow.
Our process
Discovery & AI audit
Mapped existing ordering pain points and identified where AI could eliminate friction — focusing on phone orders and order accuracy.
Conversation design
Designed the full WhatsApp conversation flow, including menu navigation, customisation options, and payment handoff.
AI model integration
Integrated OpenAI's API for natural language understanding, trained on menu items and common order variations.
Payment & kitchen integration
Connected Stripe for secure in-chat payments and built a real-time feed into the kitchen display system.
Testing & deployment
Ran two weeks of beta testing with real customers, refined edge cases, and deployed to production.
