Two kinds of item, one list
Enter the plant-supply lines with full specifications — size, grade, brand — because those invoices are checked against orders, and the township retail lines quickly with their units and GST rates. Both sit in the same item list and bill from the same screen, which is what stops a shop running two systems for two kinds of customer.
Plant supply and township retail
Bhilai's dealers work around the steel plant, handling rebar and structural material for contractors working to specification, alongside a steady retail trade serving the township housing. The two need very different billing out of the same stock.
Two documents, one system
A plant contractor needs a referenced invoice with HSN codes and line-wise tax that his accounts department will clear; the township customer needs a bill in thirty seconds. Both are the same document here with different fields filled, updating the same stock and the same ledger — which is what stops a shop running two systems that stop agreeing.
Size-wise stock
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 rate. A shop keeping one item called Steel can state its total tonnage and nothing anybody actually asks about.
Setup and support
Setup is a thirty-minute call covering your details, sizes as separate items, parties with their balances and your bill format. Support afterwards runs in Hindi on phone and WhatsApp, Monday to Saturday.
