A challan is a delivery note: it travels with the goods and records what left the building, for whom, and at what value. Every one issued is kept here with the address and prices it carried on the day — so reopening an old challan shows what the vendor actually received, not what today's price list says.
No vendors yet. Add one here, or create the first while issuing a challan.
