High-Throughput Vision OCR Engine: 92.4% Straight-Through Processing at 450,000+ Documents/Month
Architected an end-to-end Vision-Language document intelligence pipeline replacing manual data entry for unstructured medical invoices, provider licenses, and complex claims tables. Reduced document cycle time from 3 business days to 28 seconds while delivering complete extraction and intelligent processing on top at $1,000 per 1,500 documents (vs $15.20/doc legacy manual entry).
The Legacy Bottleneck: Manual Data Entry & Cost Escalation
The client processed over 450,000 monthly multi-page invoices and healthcare credential packets across 40 disparate vendor formats. Manual entry teams spent an average of 8.5 minutes per document copying provider NPIs, table line items, and tax identifiers into legacy ERPs. The process suffered from human fatigue errors (4.8% field error rate), ballooning operational costs to $15.20 per document and creating an unmanageable 72-hour payment backlog.
- •72-hour average processing backlog causing severe provider credentialing and payout delays.
- •$15.20 fully loaded manual handling cost per document across staff hours and audit reconciliations.
- •4.8% manual entry error rate leading to billing disputes, compliance audit flags, and repeated rework.
Dual-Stage Vision Transformer & Intelligent Processing Pipeline on Top
We engineered a containerized Vision-Language pipeline pairing LayoutLMv3 spatial segmentation with custom fine-tuned transformer token extractors. Crucially, our architecture does not stop at raw optical character extraction—we execute complete intelligent processing on top: domain-specific schema normalization, cross-registry license verification, arithmetic table reconciliation, and direct transactional synchronization with SAP ERP.
Every extracted token is scored mathematically. If any critical entity (such as tax ID or invoice sum) scores below 98.0%, or if arithmetic reconciliation fails, the document is routed to an ergonomic Human-In-The-Loop review console. Reviewers confirm with a single click, and their corrections automatically train model fine-tuning loops.
