Read the guideFrequently Asked Questions
Quick answers before you download.
Is BizBahi really free?
Yes. The Free plan lets you bill, manage stock and khata with some limits and ads. New accounts get 7 days of all features free. Paid plans (₹999/month, ₹2,999/year or a one-time lifetime license) remove ads and limits.
Does BizBahi work without internet?
Yes. Billing, inventory, khata and reports work offline on the phone. Changes sync to your account the next time you are online. Internet is also needed for Google sign-in, the web app, licenses and app updates.
Where is my business data stored?
On your phone, and — when you are signed in with Google — a synced copy on BizBahi servers so you can open it in the web app or on another phone. It travels over HTTPS and is backed up daily. You can download or delete the cloud copy from Settings → Cloud Sync. Demo mode and accounts not signed in never upload anything.
Is it available on iPhone or desktop?
Use the Android app on your phone and the web app at bizbahi.com/app on any laptop or desktop browser (also works in an iPhone browser). Both use the same Google account and stay in sync.
Is the license a subscription?
No auto-debit, ever. The lifetime license is a one-time payment. Monthly and Yearly plans are also one-time payments for 1 or 12 months — pay again only if you want to continue. Prices are on the Pricing page.
What happens if I change my phone?
Install BizBahi on the new phone and sign in with the same Google account — your synced data comes back automatically. You can still take a backup file as an extra copy.
