Client Said "Your OCR Sucks." Fixed It With One Node. Revenue Jumped $4,200/Month.
Lost 3 clients in one week. All same complaint "Your OCR accuracy is garbage."
THE HUMILIATING NUMBERS
Medical forms: 67% accuracy
Handwritten notes: 41% (basically useless)
Scanned invoices: 72%
Mixed format documents: 58%
Was using standard OCR for everything. Like using a hammer for brain surgery.
THE REVELATION
Not all documents are created equal. Printed invoice? Standard OCR. Handwritten medical form? Needs specialized processing. Table-heavy financial report? Different approach entirely.
REBUILT WITH INTELLIGENT ROUTING (n8n)
Document analyzer node (determines type)
Router based on document characteristics
Path A: Clean PDFs (standard extraction)
Path B: Handwritten (enhanced AI processing)
Path C: Tables (structure-aware parsing)
Path D: Mixed formats (multi-pass approach)
Confidence scoring and human fallback
Unified output regardless of path
THE SHOCKING RESULTS
Medical forms: 67% to 96.8%
Handwritten: 41% to 89.2%
Invoices: 72% to 99.1%
Mixed formats: 58% to 94.3%
Called back lost clients with free trial. All three returned. Plus referred others.
REVENUE IMPACT
Before: $2,800/month (and dropping)
After: $7,000/month (and growing)
Cost increase: $34/month for enhanced processing
THE LESSON
Stop forcing one solution on every document type. Route intelligently. Use the right tool for the right job.
Running this approach for 6 clients now. Setup time? 90 minutes. They think I'm a wizard. I just use a router node.
What document type is killing your accuracy?
