TMT size by size
The item list here is dominated by steel, and every size should be its own item: 8mm, 10mm, 12mm, 16mm, 20mm and up, plus angles, channels and sheets by dimension. Each carries its own rate, updated once each morning, and its own stock. Cement and the general building lines sit alongside. That structure is what makes both the bill and the stock figure usable.
A steel town's rebar trade
In Durgapur the rebar business works at a scale a general counter never sees. Dealers around Benachity and City Centre hold TMT across eight or ten sizes plus angles, channels and sheets, and the buyer is usually a contractor rather than a walk-in. The rate follows the mills and moves before the shop opens, so what a dealer quotes at nine is not what he quoted yesterday.
Size-wise stock, or no stock at all
A contractor asking whether you have four tons of 16mm expects an answer in seconds, and that is only possible if each size is its own item with its own stock and its own rate. A shop keeping one item called Steel can tell you its total tonnage and nothing anybody actually asks. Separate items also mean the reorder list reads as a list rather than a guess.
Billing at this morning's rate
The most expensive small mistake in a steel town is a staff member billing at yesterday's number because that is what they remember. Updating the rate on the item once each morning applies it to every bill afterwards — the counter, a supervisor at a site, a second branch. Where a builder has an agreed price it is held against him, so nobody has to know it or ask.
Setup and support from Kolkata
Durgapur is served from our Kolkata office, so setup is done over a phone call and screen share of about thirty minutes, with a visit where a shop genuinely needs one. Support afterwards runs in Hindi, English or Bengali, and a screenshot on WhatsApp usually settles a problem in the first reply.
