About this case study: it is based on a business typical of the ones we work with, not a named client, and every number comes from the assumptions at the end of the page. Swap in your own and the sums still work.
The problem
About 40 children are absent on a normal day. The office calls each parent, many calls go unanswered, and by the time a worried parent finds out it is afternoon.
Fee reminders go home as printed slips. Circulars are forwarded into class groups in Gujarati and English, and the office answers the same questions on the phone.
What we build
- 1
Absence alerts
Teachers mark attendance on a phone or tablet. Parents of absent children get a WhatsApp message by 10 am and can reply with a reason.
- 2
Fee reminders with a UPI link
Reminders go before and on the due date, in Gujarati or English, and stop once the fee is paid.
- 3
One broadcast for circulars
Circulars go out once, to every parent, with a short FAQ answered automatically.
- 4
Admission enquiries
Enquiries from the website and walk-ins land in one list, with a follow-up message and a visit slot.

Where a person stays in control
Messages only go to the parent numbers the school has on record, and anything about a child's wellbeing goes to the class teacher, not a bot.

How the numbers work
- 40 absences a day, 2-minute calls, 24 school days ≈ 32 hours a month.
- Fee reminder calls: about 30 hours a quarter ≈ 10 hours a month.
- Answering repeated questions: 1 hour a day × 24 days = 24 hours.
- Office time costed at ₹200 an hour: 66 × ₹200 = ₹13,200.
