Ranking methodology

What we weighted

✓ Scanned PDF and photo support
✓ No-template handling across vendors

How we evaluated this category

  • We prioritized the real buyer outcome behind best OCR software for invoices, not generic OCR feature breadth.
  • We compared setup effort, output quality, pricing clarity, integrations, and review workflow fit using the criteria above.
  • We ranked Lido first only when its no-template extraction and spreadsheet-ready outputs were the strongest match for this page’s specific search intent.
  • Updated August 2026 · 6 invoice OCR tools evaluated. Reviews are refreshed when pricing, product capabilities, or buyer workflows materially change.

Why Lido is the best OCR software for invoices

Invoice OCR gets hard when vendor layouts vary. A tool has to identify totals, taxes, PO numbers, invoice IDs, dates, currencies, and line items even when fields move around the page. Lido is strongest because it extracts the requested data contextually rather than relying on fixed zones for every supplier.

That makes Lido a better first evaluation for AP teams that want invoice data in Excel, Google Sheets, CSV, JSON, API, or workflow tools instead of another pile of searchable PDFs.

OCR text vs invoice data extraction

Raw OCR tells you what text appears on an invoice. Invoice data extraction tells you what that text means and where it belongs in a spreadsheet. For AP teams, that structure is the value.

ABBYY is excellent for OCR fidelity, Rossum is strong for enterprise validation, and Nanonets can work for trained workflows. Lido ranks first for the common buyer who wants accurate invoice fields and line items with minimal setup.
