Banana money and the building year
Construction across the district is funded by horticulture income, which arrives on its own calendar rather than a single harvest. That spreads demand differently from a grain district and makes the movement report over the same weeks last year more useful than a general seasonal assumption.
Supplying towns across the belt
A good share of the trade goes to shops and contractors across the district rather than over a counter. Agreed rates per party, credit limits set before a load leaves, and challans recording the vehicle and destination are what that half of the business needs.
Long deliveries and the record
A load going out an hour or two to a buyer seen occasionally needs a challan that survives — date, vehicle, destination and the name of whoever received it, held against the party and resendable on WhatsApp months later.
