Many businesses still request invoices by fax — TigerFax lets you send them from your iPhone in seconds.
Download TigerFax
Install TigerFax from the App Store on your iPhone 13. It's free to start — no credit card required.
💡 Tip: TigerFax is optimized for iOS 15+ and works on all iPhones running iOS 15 or later.
Scan your Invoice with iPhone 13
Open TigerFax and tap the camera icon. Position your iPhone 13 about 12 inches above the Invoice and let the auto-capture detect the edges. The iPhone 13's sensor-shift OIS on the wide camera reduces camera shake during document scanning. For best results, scan in a well-lit area and let the auto-capture trigger automatically.
Upload your Invoice from iPhone 13
Alternatively, tap the upload icon to import your Invoice from Files, iCloud Drive, or any connected cloud storage. iOS 15 on iPhone 13 supports Quick Note and improved Shortcuts integration, so you can create a shortcut to open TigerFax and start a fax directly from your home screen.
💡 Tip: PDF format preserves Invoice formatting best. If you have a digital copy, upload it instead of scanning for the clearest result.
Enter the recipient's fax number
Type the recipient's fax number in the To field. For international numbers, include the country code. TigerFax automatically formats the number.
Review and send
Preview your Invoice to verify all pages are included and legible. Tap Send. You'll receive a delivery confirmation when the fax is received.
