AI sales rep for inbound
The bot booked 120 students. Half of them while the team slept.
Online English school, students worldwide
Live since February 2026
What it was like
- The sale starts with a free trial lesson: someone leaves a request, a manager reaches out on WhatsApp and books them in.
- Students are spread across the world, almost half of them in the US. The team is in another hemisphere.
- Requests came in around the clock, and at night nobody could answer: by the time a manager woke up, the lead from Dallas had forgotten they ever asked.
Where it got difficult
- Teacher availability lives in a Google Sheet and changes constantly.
- "Tomorrow at six" means two different moments for a student in California and for the teacher.
- Off-the-shelf bots break here: they confuse dates and zones and offer slots that are already taken.
What was built
- An AI manager on WhatsApp replies instantly and carries the conversation from request to a booked trial lesson.
- It checks the live schedule and offers only slots that are genuinely free.
- A dedicated time-zone and date engine understands "tomorrow" and "on Wednesday" and converts the student's time into the teacher's.
- The team kept the spreadsheet they were used to: they work in it exactly as before, the bot reads the same sheet.
- Follow-ups: the bot chases both people who never replied and those who went quiet mid-conversation.
- Hard cases go to a human manager with the reason attached.
- Bot-or-human mode per contact: the team takes over any conversation with one click.
- Every booking is logged to the team Telegram group.

a month to run it all: the model, the WhatsApp gateway, the server
A lost request costs you the average deal multiplied by your conversion to payment. At a ₽30,000 deal and 30% conversion, every person who never booked is ₽9,000 gone. Ten a month is ₽90,000, and over a year more than a million.
