// Case Study
A Twilio and OpenAI SMS chatbot books pet-grooming appointments around the clock through natural language. No app, no web form, just a text thread from first inquiry to confirmed booking.
The problem
Good Sniff Spaw took bookings manually over SMS and phone. After-hours requests were missed, and the team spent real time on back-and-forth scheduling.
Nothing connected incoming texts to their scheduling system, so every booking meant a person copying details across by hand.
A Twilio SMS chatbot on n8n that runs the whole booking in one text thread.
Incoming texts hit a Twilio webhook and route into n8n, where OpenAI handles the full conversation naturally.
The bot understands the request in plain language and gathers the details it needs to book, no rigid menus or keywords.
Before confirming, the bot checks availability against Google Sheets so it only ever offers slots that are actually open.
The bot confirms the booking and creates the HubSpot contact record automatically, with no human involvement.
Appointments booked 24/7 via SMS without staff involvement.
Natural conversation from the first text to a confirmed booking.
HubSpot contact records created automatically on every new booking.
No app and no web form required, just a text thread customers already use.
Availability checked live against Google Sheets so offered slots are always open.
