Quick Answer
Why This Business Workflow Matters
Manual invoice entry is slow, but automated extraction can still make mistakes when layouts vary or scans are unclear.
Good business document workflows separate extraction, review, approval, and decision-making. AI can help prepare the review, but it should not become the final authority.
Step-by-Step Guide
- Capture readable invoice text with PDF extraction or OCR.
- Extract standard fields.
- Compare totals and line items.
- Flag missing or low-confidence fields.
- Send exceptions to a human reviewer.
Best Practices
- Text-based PDFs are easier than blurry scans.
- Line items need careful review because layouts vary.
- Extraction should never be the same as approval.
Common Mistakes
- Treating extracted data as approved data.
- Ignoring low-quality scans.
- Skipping duplicate checks.
- Not reviewing payment instructions.
