The Problem

Traditional OCR requires template development for every invoice format. Each new supplier = 2-4 weeks setup + €5,000 cost. With 60 ERP integrations, that's 60× the complexity.

The result? 85-95% accuracy, high maintenance burden, slow customer onboarding, and competitive disadvantage as OCR becomes commoditized.

The real value isn't extraction—it's the 33 years of ERP integration expertise.

The Solution

Replace template-based OCR with Claude 3.5 Sonnet. One LLM call extracts any invoice format with 98-99% accuracy—no templates, no setup, no maintenance.

Upload PDF → Claude extracts structured data → Validate → Route to ERP. Total processing: 12 seconds at €0.02 per invoice.

Keep competitive advantage (ERP integrations), eliminate competitive liability (OCR templates).
