Rice milling looks simple from outside: buy paddy, dry, hull, polish, sell rice. Inside, the owner is juggling farmer payments by weight and moisture, dozens of lots of different varieties, drying loss, hulling percentages that change with the paddy, by-products with their own buyers, and traders who take rice on credit and settle when they can.
Thirvusoft has implemented ERPNext for rice mills including RP Ricemill and VSN Ricemill, and our blog carries rice-mill guides written from that work. This page describes how a mill's daily flow fits ERPNext without a separate rice-mill package, and where a little customisation, such as weighbridge capture and moisture deduction, makes the difference.
Paddy procurement: weighbridge, moisture and farmer settlement
Procurement is where the mill's money goes out, so it is where records must be tightest. Each lorry or tractor load becomes a purchase receipt in ERPNext with the farmer or commission agent as supplier, the variety as the item, and a batch number for the lot. Gross, tare and net weight come from the weighbridge; Thirvusoft connects the indicator where the hardware provides a data output, and otherwise the operator keys the two readings and the system computes net.
Moisture and quality deductions are entered on the same receipt. We configure the deduction rule the mill already uses, whether a percentage above a moisture threshold or a fixed quantity per bag, so the payable quantity is calculated rather than argued at the counter. Payment entries settle farmers by cash, bank or advance adjustment, and the agent's commission is booked separately.
- Vehicle number, bag count, gross, tare, net and moisture on every receipt
- Variety and season carried on the batch, so yield can be compared across lots
- Advances to farmers tracked as supplier advances and adjusted on settlement
Drying, hulling and by-products: recording yield honestly
Once paddy is dried and milled, one input becomes several outputs: head rice, broken rice, bran, husk and sometimes rejection. ERPNext records this with a manufacture entry driven by a BOM that lists the by-products, or with a repack entry where the operator enters what came out. Either way, the paddy batch is consumed and each output appears in the finished-goods godown with its own quantity.
The value of the paddy is split across the outputs based on the rates you set for each, so bran and husk carry a small share and head rice carries a realistic cost. Drying loss is recorded as its own entry, not hidden inside the milling figure. From these entries ERPNext reports yield percentage per batch and per variety, which is the number every mill owner is really watching.
Milling cost per quintal
Paddy is the largest cost, but power, labour, packing material, dryer fuel and machine upkeep together decide whether a quintal of rice makes money. ERPNext captures these as additional costs on the manufacture entry or as expenses booked to a cost centre for the milling plant. With production quantity known from the same entry, cost per quintal by variety and by month is a report, not a spreadsheet exercise.
Hullers, polishers and colour sorters can be tracked through the asset module, so repairs and depreciation are part of the picture too, rather than sitting only in the balance sheet.
Godowns, bags, varieties and stock counts
A mill keeps paddy in one or more godowns and rice in another, often with separate stacks by variety and grade. ERPNext warehouses map to godowns, item variants map to variety and grade, and unit-of-measure conversions handle bag, kg and quintal so a stock report reads in whichever unit the reader thinks in. Broken rice, bran and husk are ordinary items with their own buyers and price lists.
Physical counts are reconciled with a stock reconciliation entry, and the stock ageing report shows which lots have been sitting longest, useful when older paddy should be milled first.
Dispatch, e-way bills and credit sales to traders
Rice moves out by the lorry to wholesalers, traders and retailers, many of whom buy on credit. The sales invoice carries bag count and weight, the e-way bill is generated from the invoice through the India Compliance app, and the delivery trip document records vehicle and driver. Where the mill sells through its own counter, ERPNext point of sale handles cash sales against the same stock.
Each trader has a credit limit, and the receivables ageing report shows who is over terms. Payment entries handle part payments and advances, and invoices or reminders can go out over WhatsApp through Thirvusoft's integration so collection follow-up does not depend on one person's memory.
What the owner sees each morning
The point of all this recording is a short set of numbers on the owner's phone or desktop. ERPNext dashboards and reports are configured for them, and the mobile view works in a browser without any extra app.
- Paddy stock and average purchase rate by variety
- Yesterday's milling, with yield by lot
- Rice stock by grade and godown, and today's despatch
- Receivables ageing by trader
- Cost per quintal for the month so far
Bringing a mill live on ERPNext
The implementation follows Thirvusoft's standard route: discovery at the mill, configuration of varieties, godowns, deduction rules and print formats, migration of ledgers and opening stock from Tally or Excel, role-wise training in Tamil for the weighbridge operator, supervisor and accountant, then go-live with hyper-care support and an annual maintenance contract afterwards.
Most mills fit inside the 8 to 14 week window we quote for manufacturing units. ERPNext has no licence fee, and an SME implementation typically starts within a few lakh rupees; we give a fixed-price quote after discovery. Mills in Erode, Coimbatore and across Tamil Nadu get on-site visits, and remote support covers the rest.
