01What IDP is, in one paragraph
Intelligent Document Processing is OCR + classification + structured extraction + validation, glued into a workflow. Done right, it removes manual review from 60–90% of incoming documents.

02The four-stage pipeline
- 1
Pre-processing & OCR
Deskew, denoise, run high-quality OCR. Modern OCR (AWS Textract, Azure Form Recognizer, Google Doc AI) is usually better than your team can build.
- 2
Classification
Classify the document type (invoice, contract, receipt, claim form). Drives which extraction template runs next.
- 3
Extraction
Pull structured fields. Use templated extraction for stable layouts; use an LLM with grounded prompts for variable ones.
- 4
Validation & routing
Check business rules (totals match, dates valid, customer exists). Confident docs go straight through; uncertain ones route to humans.
03When to use LLMs vs models
Templated
Field-position model
- Stable layouts (W-9, standardized invoices)
- Highest accuracy on familiar forms
- Cheap inference
LLM-based
Grounded extraction
- Variable layouts
- New document types without retraining
- Lower per-document setup cost
04Validation is where ROI lives
Extraction without validation is a partial answer. Validation moves the system from "draft" to "approved" without a human.
- Cross-field consistency (line items sum to total)
- Lookup checks (vendor exists, PO is open)
- Reasonableness bounds (totals within historical range)
- Confidence-based routing (low-confidence → human queue)
05A confidence-based router
routing logic
def route(doc):
if doc.classification_confidence < 0.85:
return "human_classify"
fields = extract(doc)
if any(f.confidence < 0.8 for f in fields):
return "human_review"
if not validate(fields):
return "exception_queue"
return "auto_approve" # straight-through06Operationalize feedback
When a human corrects an extraction, capture it. Those corrections become your next training set.

IDP wins on workflow design, not on raw model accuracy. Confidence-based routing, validation, and a feedback loop are what get to 80% straight-through.
