- Farmer (consignor) and buyer (purchaser) names
- An arhtiya acts between farmer and trader. The patti issued to the farmer and the sale bill issued to the buyer should both name the other party, the lot and the auction date so the deal can be traced through the mandi records.
- Lot, commodity and auction rate
- Each lot is auctioned separately. Commodity, variety, number of bags, net weight and the auction rate per quintal must be shown so the farmer can verify his payment against the mandi's auction register.
- Commission percentage and amount
- Commission rates are usually fixed by the state's market committee rules. Printing the percentage and the rupee amount separately keeps commission visible as the agent's own income, distinct from the produce value.
- Hamali, weighing and other charges
- Loading, unloading and weighing charges are collected on behalf of labourers or the market. Listing them separately prevents them being treated as part of the agent's commission or the farmer's price.
- Market fee and APMC licence number
- Market fee or cess is a state levy, not GST. The agent's licence number under the state APMC Act identifies the shop in the mandi records and should appear on every patti.
- Whether the produce is agricultural produce
- Whole grains, fresh vegetables and raw cotton are agricultural produce; dal, gur and processed spices are not. A one-word note per lot supports the nil rate on commission.
