A mill buys raw grain by weight, processes it, and produces a main product plus several by-products. The business is decided by yield: how much rice comes out of a quintal of paddy, and what the bran, broken rice and husk fetch.
Mills that do not measure yield per lot are running on an average they have never verified.
Procurement
• Supplier or farmer record
• Lot-wise purchase: variety, quantity, rate
• Moisture content at receipt, which affects both price and yield
• Weighbridge entry: gross, tare, net
• Quality parameters: broken percentage, foreign matter, discolouration
• Deductions applied per your purchase terms
• Payment terms and settlement
Moisture is the single most consequential number at the gate. Record it per lot, not per day.
Storage
• Godown-wise and lot-wise stock
• Variety and quality grade kept separate
• Drying operations recorded, with weight loss
• Fumigation and treatment records
• Stock ageing
Weight loss during drying must be recorded as a process loss, not discovered as an unexplained shortage.
Milling and yield
The core of the system:
Paddy input (quintals)
↓ milling
Head rice + broken rice + bran + husk
Record per batch:
• Input quantity and lot reference
• Output: each product with its weight
• Process loss
• Yield percentage per output
• Machine, shift and operator
Then compare against your standard yield. A batch producing noticeably less head rice than standard is telling you something: raw material quality, machine setting, or an operator issue.
Yield variance by lot and by shift is the report that pays for the software.
By-products are revenue, not waste
Bran, broken rice and husk have real markets.
• Each tracked as stock with its own rate
• Sales recorded separately
• Margin contribution measured
Mills that treat by-products casually leave meaningful money on the table. Bran in particular has a volatile market rate worth tracking.
Custom milling (job work)
Many mills process grain owned by farmers or traders.
• Customer’s paddy received, with weight and moisture
• Milling charges per quintal
• Output returned: rice, with agreed treatment of by-products
• Whether by-products stay with the mill, which must be in writing
• Balance of customer-owned stock held at the mill, at any moment
That last report matters: customer-owned material in your godown is a liability you must be able to state exactly.
Packing and sales
• Packing in standard sizes: 5 kg, 10 kg, 25 kg, 50 kg
• Brand-wise packing, if you sell under your own brand
• Bag stock and packing material consumption
• Sales by variety, grade and pack size
• Dealer and wholesale pricing
• Credit customers and outstanding
Government and regulatory
Rice milling in India involves procurement and levy obligations in some states, FSSAI food business requirements, weights and measures rules for packaged commodities, and documentation for movement of foodgrain.
Requirements differ by state and change. Confirm current obligations with your association, your CA and the relevant authority. This article is not regulatory advice.
Your records should support whatever returns and registers you are required to maintain.
Weighbridge integration
Where you have a weighbridge, connecting it removes manual entry errors at the single most financially sensitive point.
• Automatic gross and tare capture
• Vehicle number recorded
• Photograph at weighing, where volume justifies it
See our API integration guide.

Frequently asked questions
Is this only for large mills? No. Even a small mill benefits from lot-wise yield tracking, which is the main profitability driver.
Can it handle both own milling and job work? It should. Keeping customer-owned stock separate from your own is essential.
What is the most common gap? Not measuring yield per lot, so poor-quality purchases are never traced back to the buying decision.
