WhatsApp Chat Assistant
Serve Customers, Take Orders & Boost Sales — All Through WhatsApp
This workflow enables restaurants to turn WhatsApp into an intelligent, automated ordering and customer service channel. By combining RAG (Retrieval-Augmented Generation) with AI, it allows customers to ask questions about the menu, check delivery zones, and place orders — all through natural chat, without human intervention.
A sample of the AI assistant in action
Customer: “What’s on the menu today?”
Assistant: “Here’s today’s menu:
- Jollof Rice with Chicken — ₦2,500
- Egusi Soup with Pounded Yam — ₦3,000
- Grilled Catfish — ₦3,500
Would you like to place an order?”
Customer: “Yes, I want Jollof Rice and a Coke.”
Assistant: “Great! I’ll need your full name and delivery address to proceed.”
Workflow Overview
The WhatsApp AI Chat Assistant transforms casual customer messages into structured interactions. Customers chat naturally in WhatsApp while the system:
- Answers menu and policy questions using uploaded PDF/CSV data
- Guides users through a smooth process
- Collects necessary customer details (name, items, address)
- Sends confirmed orders directly to restaurant staff
- Maintains conversation memory for personalized service
No app downloads. No forms. Just WhatsApp — and AI-powered hospitality.
The Challenge
Restaurants often struggle with:
- High volume of repetitive menu and delivery inquiries
- Order errors due to miscommunication over phone or chat
- Limited staff availability for live chat support
- Difficulty scaling customer service during peak hours
- Lack of automated order logging and tracking
Manual order-taking is slow, error-prone, and hard to scale — especially for small to medium-sized eateries.
The Automation Solution
A customer sends a WhatsApp message like:
“Do you deliver to Oke-Fia and what’s your spicy rice price?”
The AI assistant:
- Searches the restaurant’s knowledge base (uploaded menu/delivery PDF)
- Returns accurate pricing and delivery info
- Guides the customer toward placing an order
- Collects missing details step-by-step
- Once all info is gathered, confirms the order and sends it to the kitchen
- Replies with a friendly, branded confirmation — all in real time
