Lakshmi's Delivery Verify

Schools tick off what actually came off the cart, at the gate, before anyone signs the challan.

Who this is for

Lakshmi Venkatesan runs Sri Balaji Stationers, two lanes behind the bus stand in Erode. Eleven schools, one tempo, two delivery boys and a nephew who does the billing. At 7.20 in the morning the tempo stops at St. Ann's gate, the watchman calls the office clerk, and the clerk has about ninety seconds to accept forty cartons before the assembly bell goes.

How the job is done today

The delivery boy carries a carbon-copy challan. The clerk signs the top copy without opening a single carton, because the bell is about to go and there is nowhere to stack forty cartons at a gate. Three weeks later the school's accounts sir rings up: sixty long notebooks short, and the payment stays stuck. Lakshmi has a signature and nothing else. The nephew opens the WhatsApp group, the delivery boy says he counted them, the clerk says nobody counted anything, and in the end Lakshmi writes off the sixty notebooks to keep the school.

The screens, in order

1. Make the day's delivery — Lakshmi turns a school's order into a checkable list and prints a small square code on the challan the tempo carries.
2. The gate check — The clerk scans that code on their own phone and sees the whole order on one screen, everything already counted as received, so the only thing left to do is tap what is wrong.
3. Short or torn — When a line is tapped, this asks the one question that matters, how many are missing or damaged, and nothing else.
4. Sign and hand back — The clerk puts their name and signs with a finger, and both the school and the shop end up holding the same record of what actually came off the cart.
5. The morning list — Lakshmi watches which schools have accepted clean and which have flagged a shortfall while the tempo is still out on the round.

What it keeps track of

• Schools — name of the school, which gate the tempo goes to, who signs at that gate, phone number of the office
• Orders — which school, which day, what was ordered and how many of each, who packed it
• Gate checks — which order, what time the tempo reached, what the clerk accepted, what was short or torn and how many, the clerk's name and signature
• Shops paying for this — shop name, town, how many schools they supply, what they pay each month, paid up to which date

The one decision that matters

The whole order has to sit on one screen at a gate, and a school order runs to twenty-five lines. Two ways to do it. One, show a single item at a time and let the clerk tap yes or no, twenty-five taps, nothing to scroll. Two, show all twenty-five lines small and quiet, every line already counted as received, and let the clerk tap only the ones that are short. Go with the second. The clerk has ninety seconds and a bell coming. Twenty-five taps gets rushed and turns into twenty-five yeses, which is exactly the worthless signature Lakshmi is already holding. Tapping only what is wrong is what the clerk is doing in their head anyway, and a shortfall list that stays empty is an honest empty list.

What to leave out of the first version

No photographs of torn cartons. It is the obvious thing to add and it is the one thing that will not load on a phone at a school gate on a weak morning signal. A line saying six of forty are torn, with a clerk's name against it, settles the same argument. Also leave out collecting money from the other shops. Take their fifteen hundred a month on UPI by hand until there are thirty of them. Building payment collection before there is anyone to collect from is a month spent on nothing.

How you would know it worked

The tempo pulls away from St. Ann's gate in under two minutes, and sixty long notebooks show up as short on Lakshmi's phone before it reaches the next school, so the balance goes out the same afternoon and the accounts sir never rings.

Build it

Paste this in and let it run.

I run a stationery shop in Erode and supply eleven schools. Build me a website where I enter the day's order for a school and print a small square code on the challan, so the office clerk at the gate can scan it on their own phone. They should see the whole order on one screen with no scrolling, every line already marked as received, and they only tap the lines that are short or torn and put the number. Then they type their name, sign with a finger, and it is finished inside a minute. On my phone I want to see which schools accepted clean and which flagged something while the tempo is still on the round, and I want to look up any old delivery when the school accounts man asks. It must work on a slow connection at a gate, and let me add other shops later because I mean to sell this to them.
