OCR for Invoices and Receipts: Best Practices

Invoices and receipts are among the most common OCR use cases—but also among the trickiest.

Challenges with invoice OCR

• multiple fonts and sizes,
• tables and totals,
• currency symbols and VAT numbers.

Best practices

• Scan at 300 DPI.
• Keep the document flat.
• Crop unnecessary margins.
• Export to DOCX for structure.

After OCR: always verify

Double-check totals, tax values, and invoice numbers—these fields matter most.
