Why Your Document Extractor Breaks on the Contracts That Matter Most
Your invoice parser probably works fine. Feed it a clean, digital PDF from a Fortune 500 vendor — structured rows, consistent column widths, machine-generated text — and it will extract line items with near-perfect accuracy. Then someone uploads a multi-page contract from a regional supplier, a scanned form with handwritten amendments, or a financial statement where the table header lives on page 3 and the rows continue through page 6. The extractor fails silently, returns partial data, or confidently produces structured output that is wrong in ways no downstream validation catches.
This is the central problem with enterprise document intelligence: the documents that break your system are not the edge cases. They are the ones with the highest business value.
