How to fix common OCR errors in receipts

OCR accuracy depends on the quality of the document. Wrinkled paper, glare, low contrast, handwritten notes, and tilted photos can all create mistakes. The goal is not perfection on every scan; it is a reliable review process.

Start with dates. OCR may confuse the transaction time with the date or misread short date formats. Standardize dates before sorting or reporting.

Then review money fields. Total, tax amount, and subtotal should make sense together. A missing decimal point or extra digit can change an expense dramatically. If a receipt has multiple tax lines, verify that the total tax field is the one you use for reporting.

Vendor names are another common issue. Card brands, payment processors, or bank names may be detected as the vendor. Correcting vendor names makes later analysis more useful.

To improve future scans, photograph receipts on a flat surface with even lighting and include the full page. For PDFs, prefer text-based files when available because they usually produce cleaner extraction.

For high-value receipts, always keep a manual review step. Automation saves time, but a reviewed spreadsheet is what makes the archive dependable.
