Calc2Pay - Bill & Payment

Calc2Pay is a professional billing calculator built for small businesses — grocery shops, medical stores, tea stalls, restaurants, fruit and vegetable vendors, mobile shops, hardware stores, kirana stores, and more. Calculate the bill. Generate a payment QR. Get paid — instantly, via UPI. Calc2Pay never processes payments itself. It only generates a QR code encoded with your own UPI ID, so your customer pays you directly through their own UPI app (Google Pay, PhonePe, Paytm, or any other). SMART CALCULATOR Full calculator with GST, discount, tax, and round-off built in. Quantity × price shortcuts, memory functions, undo/redo, calculation history, and voice input for hands-free entry. BILL BUILDER Add items with quantity, unit, and price. Apply GST and discount per item. Instant subtotal, round-off, and grand total. INSTANT PAYMENT QR Generate a UPI payment QR from any bill or calculation in one tap. Download, share, or print it — including direct Bluetooth thermal printing (58mm/80mm). SHOP PROFILE & PRODUCTS Save your store details, logo, and payment ID. Build a product catalogue with barcode scan and generate support for faster billing. HISTORY & REPORTS Every bill is saved automatically — search, duplicate, favourite, share, or print any past bill. Track daily, weekly, monthly, and yearly sales trends with charts, and export reports as PDF or CSV. PROFESSIONAL RECEIPTS Branded PDF receipts with your logo, GST breakdown, discounts, and payment QR — ready to print or share. WORKS FULLY OFFLINE All your data — bills, products, shop profile — stays on your device. Calc2Pay works with no internet connection and no account required for its core features.
