# Dairy Sutra

> Dairy Sutra is an offline-first Android app for Indian dairies. It manages milk subscriptions, daily home deliveries, customer holidays, counter sales (barcode, UPI QR), monthly billing, payments and dues, milk collection from farmers (FAT/SNF), stock, staff and salaries, expenses, and double-entry accounting reports. It works without internet, supports Hindi and English, and users sign in with their mobile number (OTP). Currently in free early access.

Key facts:

- Audience: dairy owners, managers, delivery staff, counter staff, milk-collection staff, accountants, and the dairy's customers (each role sees only its own data)
- Works offline; syncs automatically; financial records are never silently edited (corrections are reversals/adjustments with an audit trail)
- No WhatsApp or marketing SMS; SMS is used only for sign-in codes
- Price: free during early access
