The Challenge
RetailMax processes over $400M in annual supplier payments. With 15,000+ invoices per month, their manual procurement process had become a business risk:
- 3-day processing time meant suppliers regularly chased payment status
- 4.2% error rate led to payment disputes and audit findings
- 3 FTE spent 80% of time on pure data entry
- No real-time visibility — finance leadership couldn’t see liability exposure
The Solution Architecture
Document Intelligence Layer
We deployed a multi-model extraction pipeline using GPT-4o Vision for unstructured invoices (PDFs, scanned images) and a fine-tuned extraction model for high-volume standard format invoices. The system extracts vendor details, line items, amounts, tax codes, and payment terms with 99.7% field-level accuracy.
Validation Engine
Extracted data is automatically validated against:
- Open purchase orders in SAP
- Approved vendor master data
- Contracted pricing and terms
- Duplicate payment detection
- Tax compliance rules
Intelligent Routing
Invoices that pass validation are auto-approved within business rules (amount thresholds, vendor tier, category). Exceptions are routed to the appropriate approver with AI-generated exception summaries.
SAP Integration
Real-time bidirectional integration with SAP MM/FI modules — approved invoices post automatically to SAP within minutes.
