How they actually compare
Khata and udhaar tracking
Both apps offer a genuinely free digital khata — this is where Khatabook made its name, and it's still one of the most widely used ledger apps in India for a reason: fast entry, WhatsApp-shareable statements, a clean transaction history customers can check themselves. StockMitra's khata covers the same ground, but it lives inside the same app as billing and stock. That matters most the moment a credit sale happens: on StockMitra, billing an item on udhaar creates the bill, deducts the stock, and opens the khata entry in one action, so the three records never drift apart. On Khatabook, khata is the whole product — bill and stock, if you need them, live in separate tools that don't talk to each other.
GST billing
Khatabook's free plan is ledger-only; GST-compliant billing and invoicing sit behind paid add-ons. StockMitra includes GST-ready billing with PDF invoices on its free plan from day one, alongside khata and stock tracking, so a shop that needs both a ledger and proper GST bills doesn't pay to unlock the second half of the workflow.
Stock and supplier bills
The clearest split between the two. Khatabook's product is built around the ledger use case, not physical stock — no camera-based stock-in, no purchase-bill OCR, no bulk QR label printing. StockMitra was built the other way: point the camera at a shelf to log stock in, scan a supplier's paper bill and let OCR read the line items, then print QR labels in bulk for anything without a barcode already. If udhaar is the only thing you're tracking, this won't matter. If you're also receiving and counting physical goods, it's the main reason to look past Khatabook.
Payments and offline use
Khatabook has UPI/QR payment collection built directly into the ledger — a real strength if collecting payment digitally, not just recording it, is part of your routine. StockMitra supports UPI/QR sharing on bills but doesn't build collection as deep into the khata flow itself. Both apps handle patchy connectivity: StockMitra runs fully offline and syncs when the connection returns; Khatabook's offline support is more partial, so test it against your own network first.
Language and pricing
Khatabook supports more Indian languages (12+) than StockMitra's current six — Hindi, English, Assamese, Bengali, Gujarati and Marathi. On price, Khatabook's khata itself is free; StockMitra's free plan bundles khata with GST billing and stock tracking (up to 50 items, 150 bills a month), then moves to ₹249/month past those limits.
