Milk Collection Register & Dairy Billing (FAT/SNF, cycle bills)

About the Milk Collection Register & Dairy Billing (FAT/SNF, cycle bills)

A register for a village milk collection centre, a dairy cooperative society or a small dairy that runs in your browser and keeps everything on your own device. Keep your farmers — code, name, village, milk and UPI ID — and your rate charts (made in the Milk Rate Chart Maker, imported from CSV or Excel, or typed here), with new rates from a date. At the counter, type a farmer’s code, the quantity, the FAT and the SNF or CLR, and the pour gets its rate from the chart, the amount and a numbered slip for a 58 or 80 mm roll with a QR code the farmer can keep in the Milk Passbook. A typed rate needs a reason, and milk that is not accepted is kept with no amount.

Every billing cycle — 10 days, 15 days, a week, a month or your own — gives each farmer a bill: the milk, bonuses and price differences, less cattle feed and products sold to them, advances, loan instalments and payments, with the previous balance carried on. Dispatch records the milk sent to the union with a reconciliation of litres and kg of fat collected against sent. In the free preview, slips, bills, passbooks and reports show as marked page images; a Premium pass gives the clean documents.

Common uses

• A village collection centre or a dairy cooperative society that tests milk with an analyser and pays farmers every ten days.
• A small private dairy buying from farmers on its own chart and selling to a union or a plant.
• A centre that sells cattle feed and gives advances, and takes them off the milk bills.
• A secretary who wants each shift’s milk and fat reconciled with what reached the chilling centre.

How a pour is priced

At a dairy cooperative society every member’s milk is tested and paid for by its fat and SNF (NDDB, the Anand pattern), from the price chart or ready reckoner the union usually gives its societies (Dairy Knowledge Portal). The register looks the pour up on the farmer’s chart — their own, or the centre’s chart for that milk — in force on the pour’s date:

• a SNF worked out from a CLR uses the chart’s own formula;
• the quantity is turned into kg (or litres) when the chart is per kg (or per litre), at your kg-a-litre figure or, if you choose, at the sample’s own CLR (1 + CLR ÷ 1,000 kg a litre);
• a blank cell or a no-price rule gives no rate: type one with a reason, or mark the milk not accepted;
• the rate on the slip is the rate paid: later changes to the chart never change a saved pour.

Cycles, bills and the farmer’s account

• A bill covers one cycle: the balance before it, plus the milk and any bonus or price difference, less what was sold to the farmer, advances, loan instalments, other deductions and the payments made during the cycle. A minus net payable is what the farmer owes the centre, carried to the next bill.
• Loans are taken off in instalments, one a cycle, until repaid. Bonuses and price differences are added per kg of fat or per litre (or kg) for a period you choose.
• Close the cycle once its bills are paid: its pours and entries lock and its loan instalments are written into the accounts; reopen it to change anything.
• A farmer’s passbook lists every cycle with the running balance.

Slips, printers and the farmer’s passbook

• Each slip carries the slip number, date and shift, farmer, milk, quantity, FAT, SNF (and CLR), rate and amount — and a QR code. The farmer scans it into the Milk Passbook to keep their own record and check it against the chart; the slip’s details travel inside the code, so nothing is sent anywhere.
• Print dialog (any printer): the slip is drawn at the roll’s own size (58 or 80 mm wide).
• Straight to the printer (ESC/POS): in Chrome or Edge the register sends the slip to most 58 and 80 mm receipt printers that understand ESC/POS. Bluetooth reaches Bluetooth Low Energy printers only (“classic” Bluetooth printers are not reachable from a web page); on a computer, a printer on a serial port (a USB-serial printer, or a Bluetooth printer paired with the computer) works too. Picture prints every language and the QR code; Text is faster and prints English letters only. Print a test slip first.
• Slips, bills and reports can carry their headings in Hindi, Marathi, Gujarati, Punjabi, Telugu or Kannada beside the English.

Milk sent and reconciliation

Record each dispatch — quantity, FAT and SNF, the rate from your sale chart or typed — and, when the union or plant sends them, their own figures. The Dispatch tab and the day report compare the accepted milk of the shift and the day with what was sent: the difference in kg and kg of fat, as a share of what was collected, and the sale value against what the farmers are paid.

Your data stays on this device

• Farmers, pours, charts and accounts are kept in this browser on this device (IndexedDB). Nothing is uploaded, and you don’t need an account.
• Set a passcode under Data & backup to keep the register encrypted (AES-256) and locked when you step away.
• Clearing the browser’s site data deletes the register: download an encrypted backup regularly (the register reminds you) and restore it on another device to move the centre there. Your own records — farmers, every pour, the accounts and the milk sent — also download as CSV, also without a pass; a cycle’s bills download as CSV and Excel with a Premium pass.

A privacy notice for farmers (India)

Under India’s Digital Personal Data Protection Act, 2023 the centre is the Data Fiduciary for its farmers’ data, and section 5 asks for a notice when consent is requested: the personal data and the purpose, how to withdraw consent and use the grievance process, and how to complain to the Data Protection Board, in English or a language of the Eighth Schedule. Rule 3 of the DPDP Rules, 2025 asks for an itemised description of the data in clear and plain language that stands on its own. The template under Settings → Privacy notice for farmers is filled in with your centre and contact; rule 14(3) sets at most 90 days for answering grievances. It is a starting point, not legal advice: have a lawyer review it.

Limitations

• One device: the register does not sync between devices. Two tabs on the same device share it safely; to move to another device, restore a backup there.
• Readings are typed: the register does not read milk analysers or electronic weighing scales.
• Screens are in English; printed slips, bills and reports can add headings in six Indian languages.
• Direct printing needs Chrome or Edge and a printer that understands ESC/POS; others print through the print dialog.
• Messages to farmers open WhatsApp or your SMS app one farmer at a time, with the text ready for you to send; nothing is sent in bulk. A message with a slip’s or a bill’s figures is part of the result: in the free preview it is locked like the slip and the bill.

Privacy

Farmers, pours, charts and accounts are kept in this browser on this device and never uploaded. Slips and bills go only to the printer you choose, and messages are sent from your own phone.
