Dairy Bill Book: Milk Hisab

Dairy Bill Book: Milk Hisab is a milk billing and doodh khata app for milkmen (gwala), dairy farmers and milk collection centres. Write daily milk, price it by litre or by quality (Fat & SNF), and get a correct monthly milk bill for every customer. Works fully offline.

From 5 customers to a few hundred, it replaces the paper register and the calculator. Just add your customers and start writing milk.

QUALITY PRICING: FAT, SNF, LR & TS
Many dairies pay by milk quality, not only by the litre. Price each entry by Fat + SNF, by LR + TS (lactometer reading and total solids), with your own fat rate table, or with a custom formula. The app works out the rate from the readings, so every litre is priced fairly.

MORNING & EVENING MILK ENTRY
Write subah and shaam milk for each customer in a few taps. Choose cow milk, buffalo milk or any other milk type. Same quantity every day? Fill a whole date range at once.

MONTHLY MILK BILLS
Bills are made from your daily entries automatically. Save a bill as PDF, or share it on WhatsApp as a picture in Modern or Thermal style.

THERMAL PRINTER SLIPS
Print bill slips on Bluetooth thermal printers. Supports 53 mm, 58 mm and 80 mm paper.

CUSTOMER KHATA & UDHAR
Every customer has a separate ledger. Record full payments, part payments and advance amounts, and see at a glance who still owes you money.

SUPPLIER RECORDS
Buy milk from other farmers too? Keep supplier accounts in the same app. Bills show "Received" for customers and "Paid" for suppliers.

FARM EXPENSES & REPORTS
Write down feed, fodder, medicine and other costs, for one customer or for the whole farm. Monthly reports and charts show total milk, total amount and balance, so you know your real profit.

MILK CALCULATOR
Check a rate or amount quickly without saving an entry. Handy at the collection point.

BACKUP & SECURITY
Your records are stored on your phone. Back up to your own Google Drive and restore them when you change phones. Restoring or deleting data asks for your phone's PIN or fingerprint first.
