Invoice OCR line item extraction: what to look for

Line items are the hardest part of invoice OCR. Here are the extraction patterns, failure modes, and validation checks that matter for SMB workflows.

Why line items matter

Headers are easy. Line items are where most tools fail.

Common failure modes

  • Rows merge together
  • Quantities get mistaken for prices
  • Currency symbols disappear
  • Totals don’t reconcile

What “good” looks like

A usable extraction includes:

  • Description
  • Quantity
  • Unit price
  • Line total

And it should flag mismatches between the sum of line totals and subtotal.
