Two customers from one stock
A Trichy dealer typically serves an institutional contractor working on formal terms and a homeowner buying at the counter, out of the same godown. That is where paper record-keeping fails: the cash sales get billed and the credit ones get written in a register, and by year end nobody can reconcile them. A credit sale here is the same invoice marked unpaid, updating the party ledger automatically.
Institutional work runs on documents
Public and institutional buyers are paid against a process that wants paperwork at every stage — a referenced invoice, a challan naming the vehicle and receiver, and a statement that reconciles at month end. Supplying those reliably is often what decides whether you keep the account, because it determines how fast the contractor is paid and therefore how fast you are.
Long payment cycles
Institutional cycles are slow and not always predictable, which pushes your money further out than a private job would. Ageing rather than totals tells you where you actually stand, and a credit limit per contractor keeps your exposure inside what the shop can carry through a quiet quarter.
Supplying across the district
Loads go out to sites and smaller towns a couple of hours away, on hired vehicles, to buyers seen occasionally. The challan with the date, vehicle, destination and receiver is the only evidence any of it happened, and it stays against the party rather than travelling back in a driver's pocket.
Setup over a call
Thirty minutes covers your shop details and GSTIN, main items with the right units and GST rates, parties with opening balances, and your bill format. You raise a real bill before it ends, and support afterwards runs in English and Hindi.
