Why extraction quality matters
Before you match anything, check that the statement was read correctly. A poor extraction can move a date, amount, or reference into the wrong field and create a discrepancy that is not present on the original document.
Scanned and photographed statements
A statement that was printed, scanned, or photographed may have no usable text layer. Each number is part of an image rather than a character a computer can read directly. Basic PDF extraction may find nothing, or it may pick up garbled text left by an earlier optical character recognition (OCR) pass and treat it as reliable data.
Rotated and skewed pages
A rotated or skewed page can make the reference, amount, and date columns read in the wrong order. The extracted values may still look plausible, so compare them with the rendered page before you rely on the result.
Multi-format vendor statements
Multi-format statements vary by vendor: open-item or balance-forward, different column orders and date formats, multiple currencies, and letterheads that move the table down the page. A reader tuned to one layout can misread another, which means the reconciliation starts with the wrong values.
Garbled text layers and wrong join keys
A quiet extraction error is harder to spot than an empty page. Garbled text can look like a valid invoice reference. If that value becomes the join key used to match the statement line to your AP extract, the wrong lines can appear to tie out. Check the reference against the page before accepting the match.
The image is the source of truth
When extracted text and the rendered page disagree, use the page as the source of truth. Extracted text, OCR output, and parsed tables are readings of the document. Before deciding that a value is missing or the statement cannot be reconciled, check the rendered page.
How this shows up in Statement Zen's product
Statement Zen reads scanned, rotated, and multi-format vendor statements, then checks the reconciliation arithmetic against the extracted values. The pricing guarantee is straightforward: a statement we can't extract doesn't count against your monthly allowance. If extraction fails, that statement does not use your monthly allowance.
