How do I send my records to my accountant or tax advisor?

You can export all your invoices and estimates in one tap as a standard CSV spreadsheet or a bundled vector PDF archive. Your accountant can easily open the CSV in Excel or import it directly into QuickBooks Desktop, Xero, or their tax filing software.

Does the app truly work with zero cell reception?

Yes, 100%. The vector PDF compilation engine, SQLite database, template rendering, and touchscreen signature inking run entirely on your phone's physical hardware. No network connection is ever required to draft, finalize, or export documents.

Can I customize taxes, VAT, GST, and currencies?

Absolutely. You can configure single or multi-tier sales taxes, state/provincial rates, VAT, GST, and compound taxes. You can also select from 129 world currencies with customizable decimal places and symbol placement.

What happens if I lose my phone or upgrade to a new device?

You can export a versioned JSON backup file at any time. Simply save it to your local files, iCloud Drive, Google Drive, or send it to yourself. On your new phone, tap 'Restore Backup' and your entire history, client book, and item catalog appear instantly.

Do my clients need to install the app to view or pay invoices?

No! All invoices export as standard 300 DPI vector PDF files that open natively on any computer, tablet, or smartphone without any special software. Clients can scan the embedded payment QR code with their default camera app to pay via wire, Venmo, or PayPal.

Is my business or client data ever shared or uploaded to the cloud?

Never. We do not operate cloud database servers, user tracking systems, or data brokers. 100% of your business records, rates, and client contact information stay locked in your phone's on-device SQLite database.

What plans and subscriptions are available?
