Every delivery carries two numbers: what the note said, and what somebody counted.

Before

Four building sites ran on WhatsApp. Orders by phone, delivery notes on paper, and receipts retyped into a spreadsheet once a month.

Now

Everything is filed from the phone the team already carries. Every delivery records what the note said and what somebody counted, and is paid on the count.

Eight linked tables covering projects, materials, vendors, orders, deliveries, site reports and stage-wise billing — and two forms pinned in the WhatsApp group the team already used, so a supervisor files a report in a few taps on the phone in his hand, without installing anything.

A building contractor ran four active sites through WhatsApp — orders by phone, delivery notes on paper, and receipts retyped into a spreadsheet by hand once a month. Customers who wanted to know how their building was progressing drove to the site to look.

What was measured, and what it does not say.

Every figure carries its own limit. Of the eight firms we checked, not one states the method or the limits behind any number it advertises.

200 Bags of cement on the supplier’s delivery note.
194 Counted off the truck. The delivery is valued on this one.

Two things it will not do.

These are in the build because a wrong answer to any of them costs more than no answer at all.

Valuing a delivery on what the note claimed

Every delivery records two numbers: the quantity on the supplier’s delivery note, and the quantity the supervisor counted off the truck. The system stores both, works out the difference, and values the delivery on the second one.

Making anyone install anything

The forms are pinned in the group the team was already in. A supervisor files a report in a few taps on the phone in his hand.

What S J Construction says.

Approved by S J Construction for publication.

Everything ran through WhatsApp — orders by phone, notes on paper, and one evening a month lost to typing receipts into a spreadsheet. That evening is back. The forms went into the group my team was already in, so nobody had to be trained and nobody had to install anything. They argued with me about how deliveries get recorded, and they were right. They still ring to ask what is annoying us.
