What to do when receipt OCR misses the invoice number
How to handle receipts when the invoice number is missing or unclear without forcing a bad export.

The invoice number is often the strongest duplicate signal in a receipt workflow. When it is missing, the row can still be useful, but it should not pretend to be fully verified.
Short answer
Keep the row, preserve the source file, and mark it for review instead of inventing a value or exporting it as clean by default.
Why the invoice number matters
- It helps distinguish one vendor bill from another
- It makes duplicate review more reliable
- It gives finance a stable reference during follow-up
If two receipts share the same merchant, date, and amount, the invoice number is often the field that confirms whether they are truly the same document.
