“My shop is in a basement where internet is very patchy. Other apps used to freeze or show sync errors. InvoiceFine’s 100% offline SQLite database is a lifesaver — instant search on 3,000 items with zero lag.”

Frequently Asked Questions

Common questions answered.

Yes, absolutely! InvoiceFine is engineered with a strict 100% offline-first architecture. All your business records, product inventory, customer khata ledger, and sales invoices are stored directly inside your Android device using an encrypted local SQLite database. You can generate bills, print thermal receipts, and calculate GST even in deep basements or areas with zero internet coverage.

InvoiceFine natively supports all standard 2-inch (58mm) and 3-inch (80mm) ESC/POS Bluetooth thermal printers commonly used across Indian retail (such as Everycom, NGX, TVS, Pegasus, Epson, and generic Bluetooth receipt printers). Simply pair the printer in your phone’s Bluetooth settings once, and InvoiceFine connects automatically for sub-second receipts.

InvoiceFine provides 1-tap automated encrypted database backups. You can save your backup file to your phone’s internal memory, an SD card, send it to your WhatsApp/email, or save it directly into your personal Google Drive account. You have 100% ownership of your records — no third-party cloud lock-in.

Yes! You can share professional PDF invoices or formatted text summaries directly via WhatsApp with 1 tap. For Udhar Khata customers, you can send automated, polite payment reminders that include their pending balance statement and your shop’s dynamic UPI QR payment link for quick settlements.

Traditional apps rely on remote cloud servers, forcing you to pay heavy annual fees (₹2,500 to ₹5,000+ every year) and suffer delays when internet is down. InvoiceFine charges zero server fees, runs completely offline on budget Android phones, launches in under 1 second, and keeps your commercial data 100% private on your own device.

Zero hidden fees! The core app is free to use, and our Pro subscription is currently available at a special introductory price of just ₹1 for your first year (regular ₹299/year). We do not take any transaction cuts, payment commissions, or recurring monthly server charges.

Express POS is an ultra-fast counter checkout interface specifically designed for retail rush hours. You can switch seamlessly between a visual 2-column product grid and a compact list view with +/- quantity micro-steppers. Tap the camera icon beside the search bar to scan product barcodes directly with your phone's camera. You can also tap quick cash buttons (₹100, ₹200, ₹500, ₹1000) for instant change calculation or display a dynamic on-screen UPI QR code.

Yes! InvoiceFine comes with a built-in offline directory of over 10,000+ official CBIC goods (HSN) and services (SAC) codes. When adding items, simply type the name or code into the search bar, select the matching official entry, and the app automatically sets the correct tax slab (0%, 5%, 12%, 18%, or 28%).
