Works with no internet. Your records stay on your phone.

Every invoice, estimate and client record lives in your phone's own storage. There is no account to create, no password to lose, and no company — including us — holding a copy of who your customers are or what they paid you.

What "offline" actually means here

Not "syncs later". The invoice is built, the tax is calculated and the PDF is generated by your phone's own processor. Put the device in airplane mode on a site with no signal, in a basement, on a plane — the app behaves identically.

The only step that needs a connection is handing the finished PDF to WhatsApp or email, and that can wait until you have signal.

What is on the device and nowhere else

• Every invoice, estimate and receipt you have raised
• Your client list — names, addresses, phone numbers
• Your business profile, logo, signature and bank details
• Every PDF the app has generated

None of it is transmitted. There is no sync, no backup service, and no support tool that can read it. Why that matters more for invoices than for most data.

The honest trade-off

No server also means no recovery. If you lose the phone and have not exported a backup, the records are gone, and nobody can restore them for you.

That is a real cost and we would rather state it than bury it. The mitigation takes seconds — Settings, Export backup, send the file to yourself — and it is the same discipline any paper filing system needs. Moving to a new phone uses the same export.

Free, and not funded by ads

No advertising SDK, no analytics library, no tracking, and no data sold to anyone — the app ships without any of them. Invoices, estimates and clients are unlimited on the free tier.

The two exceptions, stated plainly. If you switch on the optional payment QR, the QR image is generated by an outside service, which means your UPI ID or PayPal address, the amount due and the invoice number are sent to it — leave the QR off and nothing leaves the phone. And if you buy Pro, the purchase is handled by the app store and our payments provider. Everything else, including every invoice and client record, stays in your phone's own storage.

What pays for it: free invoices carry a small "Made with EstimateBill" line at the foot of the PDF. That line is the entire marketing budget. Why an ad-funded finance app is a bad trade.
