Frequently asked questions about BillZap.
Is BillZap really free?
Yes. Every feature is free, forever — voice billing, GST invoices, UPI QR codes, WhatsApp sharing, Day Close, backups. There is no premium tier, no subscription, and no ads. We do not gate features behind a paywall the way most billing apps do.
Does BillZap work without internet?
BillZap is 100% offline. You can create GST invoices, add customers and products, and run Day Close with no connection at all. The internet is only used when you explicitly choose to share a bill on WhatsApp. Your data lives on your phone, not on our servers.
Which Indian languages does BillZap support?
BillZap supports 12 languages: Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi, Gujarati, Bengali, Punjabi, Odia, Urdu, and English. You can even mix languages in a single voice command — for example, Tamil and English together in one sentence.
Is BillZap a good Tally alternative?
For shopkeepers and small businesses, yes — BillZap is a free, mobile-first Tally alternative that creates GST-compliant invoices in minutes instead of hours. For chartered accountants and large enterprises that need deep accounting, Tally is still the standard. BillZap is built for the corner shop, not the audit firm.
How is BillZap different from Vyapar?
BillZap is free forever and built around voice billing in 12 Indian languages. Vyapar has more inventory and accounting features, but its key capabilities sit behind a roughly ₹3,499/year premium plan. If you want fast, spoken GST invoicing without paying, BillZap is the better fit.
Is my business data safe?
Your data is stored locally on your phone and encrypted with your PIN. Nothing is uploaded to any server. App Lock adds PIN and fingerprint protection with auto-relock, and encrypted backups to Google Drive let you restore on a new phone without ever exposing your data to us.
Does BillZap support UPI payments?
Yes. Every invoice automatically generates a UPI QR code using your UPI ID. Your customer scans it and the money lands directly in your bank account. You mark the bill paid in two taps — no payment gateway, no commission, no middleman.
Can I export my data?
Yes. BillZap exports your invoices, customers, and products as CSV files you can open in any spreadsheet. You can also create PIN-encrypted backups to Google Drive and restore them on any Android phone, so you are never locked in.
Is BillZap available on iOS?
BillZap is Android-only today, which covers the vast majority of Indian shopkeepers on entry-level phones. An iOS version is planned for Q3 2026.
Can I use BillZap for my kirana, restaurant, or hardware shop?
Yes. BillZap is purpose-built for the businesses real Indians run — kirana stores, restaurants, hardware shops, salons, tailors, electricians, wholesalers, and pharmacies. The voice billing, GST handling, and UPI QR work the same way for every business type.
Free billing. For everyone. Forever.
No subscription. No premium tier. No ads. No signup. No OTP. No catch.
