Without a unified system to track conversation history, staff lacked context, forcing customers to repeat information in subsequent interactions.

The Challenge
- Inefficient Manual Scheduling
Staff were overwhelmed with constant SMS and phone calls for booking, rescheduling, and cancellations, leading to delays and human error.
- Poor Customer Experience
Customers faced slow response times and could only book appointments during limited business hours, causing frustration and missed opportunities.
- Inaccurate Location Information
Manually communicating the correct service location for a specific day was inefficient and often led to confusion, no-shows, and last-minute cancellations.
- Fragmented Communication
The Solution
- AI-Powered Conversational Agent
We created an intelligent SMS agent in n8n using Google Gemini that understands natural language to book, find, reschedule, and cancel appointments.
- Seamless Scheduling Integration
The agent uses Cal.com’s API through HTTP nodes to check live availability, select suitable time slots based on duration, and instantly confirm bookings.
- Dynamic Location & Schedule Retrieval
The agent uses a Google Sheets lookup tool to instantly fetch up-to-date addresses and operating hours, ensuring customers get accurate info.
- Centralized Session & Data Management
The agent uses a real-time Google Sheets lookup tool to give customers the correct address and opening hours for any day.
Results
24/7 availability for customer interactions
40% increase in booking conversion rates
95% automation of appointment scheduling
