The Invisible Invoice: What Your School's Phone Really Costs

Nobody sends the school a bill for the phone. The office pays it anyway, in the only currency it has: hours.

Move the dials to match your own desk. The invoice adds itself up, and nothing leaves this page.

The phone sends your school a bill. It's paid in staff hours.

Set four numbers from your own desk and watch the invoice total itself — the desk hours your front office spends on the phone, the head's time the repeats pull away, and what both are worth. Nothing is uploaded; the maths runs on this page.

Head's minutes per repeat call that reach the head 3

Why 3? A call the head takes is rarely the full 5-minute version — by then it's the short, pointed one: listen, reassure, point to the answer. Three minutes is a working default, not a measurement; set it to your school's reality, or to zero if the head never gets pulled in.

The desk never gets a bill for the phone — it pays in the only currency a school office has: hours. There is exactly one way to shrink the total, and it isn't answering faster. It's answering once, where every parent can find it.

Try it twice: set the dials to your school, then to the school next door. The difference between you is the only line item anyone can act on — forward the number to whoever runs your office.

Assumptions on the meter: the calendar is whatever you set — days per week, days per month, and a term of ≈ 4 working months (one of three in the working year) · minutes-per-call and hourly value are your own selections · the 60% repeat share is an estimate for "the same handful of questions asked again" · the head's hour is valued at twice the desk rate, and the fourth dial counts only the repeat calls that actually reach the head — set it to zero if none do · treat the totals as directional, not audited. The point isn't the exact rupees; it's that the bill exists.

Reading the invoice

The total is not a saving anyone can promise. It is what the phone costs today, at your own numbers. The line worth watching is the repeats: questions the school has already answered in writing, answered again by voice.
