What is the best way to extract invoice data from PDFs?
The best approach is schema-based invoice extraction with line-item parsing, totals reconciliation, duplicate detection, confidence scores, and ERP-ready JSON.
Short answer
The best approach is schema-based invoice extraction with line-item parsing, totals reconciliation, duplicate detection, confidence scores, and ERP-ready JSON.
What this means in practice
Template-only parsing breaks when vendor layouts change. OCR-only parsing usually misses table boundaries and validation.
A production invoice workflow should extract header fields, supplier data, line items, tax, total, payment terms, PO references, and validation status.
