Thermal paper receipts fade within months, leaving you vulnerable during an IRS audit. Modern receipt scanning apps use Optical Character Recognition (OCR) to extract date, vendor, total, and tax category automatically.

1. Dext Prepare (Best for Complete CPA Integration)

Dext boasts near 100% OCR accuracy. Forward digital email invoices or snap photos of paper receipts, and it matches them directly to your bank feed in QuickBooks or Xero.

2. Shoeboxed (Best for Physical Mail-In Receipt Scanning)

If you have years of physical paper receipts, Shoeboxed sends you pre-paid envelopes ("Magic Envelopes"), scans every receipt into IRS-accepted digital format, and creates categorized expense reports.

3. Expensify (Best for Client-Billable Travel & Mileage)

SmartScan captures receipts in one snap and automatically generates professional expense reports with mileage tracking for client reimbursement.
