Commercial OCR APIs get you 70% of the way. The last 30% is where your data actually lives — line items, tax calculations, vendor-specific layouts.
The gap
AWS Textract, Google Document AI, and Azure Form Recognizer all do a reasonable job on standard forms. But invoices aren’t standard forms. Every vendor has a different layout, different field names, different ways of expressing line items.
What we do differently
We build extraction pipelines that handle the long tail — the 30% that generic APIs miss. Field-level confidence scoring, human review queues, and custom post-processing rules that understand your business logic.
