# How accurate is invoice automation OCR?
Modern invoice automation OCR achieves 95-99% accuracy for UK invoices, with advanced AI-powered systems like Elektroluma reaching 99% accuracy rates. What gets extracted: Supplier details (name, address, contact information, VAT number), invoice metadata (invoice number, date, due date, purchase order reference), line items (description, quantity, unit price, line total), financial details (subtotal, VAT amount and rate, total amount, currency), payment information (bank details, payment terms), and UK-specific data (CIS deductions, reverse charge VAT, Construction Industry Scheme details). Factors affecting accuracy: Invoice quality (clear scans perform better than blurry photos, 300+ DPI recommended), document formats (PDF text-based invoices are most accurate, followed by clear images), UK formatting (DD/MM/YYYY date formats, GBP currency symbols, UK VAT rates of 0%, 5%, 20%), and invoice complexity (standard layouts versus highly customized designs). How accuracy is ensured: (1) Machine learning trained on thousands of UK invoice templates, (2) Confidence scoring for each extracted field (flags low-confidence extractions for review), (3) Validation rules (VAT calculations must match, dates must be logical, amounts must balance), (4) Human review interface showing original invoice alongside extracted data, (5) Continuous learning from corrections (system gets smarter over time). Even with 99% accuracy, best practice is to review extracted data before exporting to accounting software - this takes 10-15 seconds versus 5-10 minutes of manual typing. Elektroluma handles challenging cases including handwritten invoices, poor quality scans, non-standard layouts, foreign language invoices (with translation), multi-page invoices with table continuation, and invoices with stamps or markings overlaying text.
