Milk Delivery Khata (doodhwala hisab and monthly bills)

About the Milk Delivery Khata (doodhwala hisab and monthly bills)

A khata for a milkman, a dairy or a shop that delivers milk to homes, tea stalls and hotels, which runs in your browser and keeps everything on your own device. Add your products — cow and buffalo milk, curd, paneer, ghee — with their rates, and your customers with what each takes every morning and evening, their route and place on it, and their own rate if they pay a different one. Every day counts as delivered unless you mark a skip or a change (guests, an extra packet of curd); the round lists who gets what, and the totals tell you how much to load.

At the end of the month — or every 15 days or every week — each customer gets a bill: a calendar of the period with each day’s milk, the products and their amounts, the previous balance, the payments and the balance due, with a UPI QR code for that amount. Record payments, part payments included, and the dues list shows who owes what. In the free preview, bills and the dues list show as marked page images; a Premium pass gives the clean documents.

Common uses

• A milkman (doodhwala) delivering to a few dozen or a few hundred homes on fixed routes, morning and evening.
• A dairy shop that delivers milk, curd and paneer to homes, tea stalls and hotels and bills them every month.
• A dairy farmer selling milk straight to households who wants each day’s milk and every payment written down.
• A seller who wants customers to pay by UPI from the bill, with the exact amount in the QR code.

How a day is counted

• A customer’s day is their usual order — the quantities they take in the morning and the evening — unless you mark it: a skip counts nothing, and a change counts what you typed, extras included.
• Days you did not mark count as delivered (a milkman delivers every day). If you would rather mark every day yourself, choose under Settings that days you did not mark count as nothing.
• Nothing is counted before a customer’s first day or after their last, or on days to come; the round of a day to come shows what is planned.
• An order changed from a date (more milk from the 15th) and a rate changed from a date (₹64 from the 1st) count from that day only: earlier days, bills and balances stay as they were.

Bills, payments and dues

• A bill covers a month, the 1st–15th or 16th–end, or a week: the balance before it, plus that period’s milk and products, less the payments received in it. What is left is the balance due, carried to the next bill; a minus figure means the customer has paid ahead.
• Each product’s amount is quantity × rate, to the paisa; a customer with their own rate pays it.
• With a UPI ID under Settings, every bill carries a UPI QR code with the amount due — the same payment link the UPI QR Code Generator makes, with your UPI ID, the name on the account, the amount and a note. The customer scans it with any UPI app; the khata does not see the payment, so record it when the money arrives.
• The dues list shows everyone who owes money now, most first, with the day they last paid.

Printing bills and reminders

• Bills come on A5 or A4, one a page, or on a 58 or 80 mm roll. Rolls print through the print dialog at the roll’s own size, or — in Chrome or Edge — straight to most receipt printers that understand ESC/POS: Bluetooth reaches Bluetooth Low Energy printers only (“classic” Bluetooth printers are not reachable from a web page), and on a computer a printer on a serial port (a USB-serial printer, or a Bluetooth printer paired with the computer) works too. Print a test slip first.
• Headings on bills can carry Hindi, Marathi, Gujarati, Punjabi, Telugu or Kannada beside the English.
• A reminder opens WhatsApp or your SMS app with the message ready for one customer — the bill’s amounts, or what they owe and your UPI ID — and you press Send yourself. Change the wording under Settings → Messages. In the free preview a reminder is locked like the bill and the dues list it comes from.

Your data stays on this device

• Customers, deliveries and payments 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 khata encrypted (AES-256) and locked when you step away.
• Clearing the browser’s site data deletes the khata: download an encrypted backup regularly (the khata reminds you) and restore it on another device to move there. Your own records — customers, the period’s deliveries and every payment — also download as CSV, also without a pass; a period’s bills download as CSV and Excel with a Premium pass.

A privacy notice for customers (India)

Under India’s Digital Personal Data Protection Act, 2023 you are the Data Fiduciary for your customers’ 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 customers is filled in with your name and contact. It is a starting point, not legal advice: have a lawyer review it.

Limitations

• One device: the khata does not sync between devices. Two tabs on the same device share it safely; to move to another device, restore a backup there.
• The khata does not see UPI payments: record each payment when the money reaches you.
• Screens are in English; bills 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.
• Reminders open WhatsApp or your SMS app one customer at a time, with the text ready for you to send; nothing is sent in bulk. In the free preview they are locked, like the bills and the dues list.

Privacy

Customers, deliveries and payments are kept in this browser on this device and never uploaded. Bills go only to the printer you choose, and reminders are sent from your own phone.
