The problem
A 200-person procurement team processed 1,200 POs/month manually. Matching POs to vendor invoices took 45 minutes per item on average.
Our approach
LangGraph agent: ingest PO → match via pgvector semantic similarity → validate against ERP API → route to appropriate approver. Guardrails prevent hallucinated vendor details from being submitted.
The outcome
$2.1M in labor cost saved in Year 1. 97% auto-match rate. 3% require human review. Zero incorrect payments in 8 months of operation.
