The number to watch
Change in total outstanding, month on month. Turnover on its own describes nothing, because a material shop can grow sales while losing money — the extra sales simply became extra credit. Rising turnover with rising outstanding and rising stock is not growth, it is working capital leaving the building. Put those three figures side by side once a month and fifteen minutes tells you more than any other report in the system.
Four lines make up most of your turnover
Cement, steel, sand and aggregate account for the bulk of what a building material shop sells, and each one behaves differently. Cement moves by the bag and spoils in damp within three months. Steel moves by weight at a rate that changed this morning. Sand and aggregate move by volume in units that vary by region. Setting those four up properly at the start — right unit, right conversion, right GST rate — is most of the setup, and everything else can be added as you sell it.
Credit is the business, not an exception
A contractor picks up through the month and settles after the builder pays him, which means a shop of any size is carrying lakhs on the street at all times. What decides whether that money comes back is not the total but the ageing: three lakh outstanding for ninety days is a different problem from three lakh for fifteen. Credit limits set in advance, a warning at billing time before the load leaves, and a statement on the first of the month are what separate the suppliers who recover from the ones who write off.
Proof that the load reached the site
Material goes to a site the shop never sees, and eight months later somebody says nothing arrived. The document that ends that conversation is a challan with the date, the vehicle number, the destination and the name of whoever signed for it, held against the party permanently and resendable on WhatsApp. In this trade one contested load is routinely several lakh, which is why the record is worth more than any counter feature.
