Invoice & AP Automation
AI pipeline that ingests vendor invoices via email, extracts line items, validates against POs, and posts to ERP.
The Challenge
AP team was keying ~8,000 vendor invoices/month by hand into SAP, with frequent mismatches against POs and slow vendor payments.
Our Solution
Email-ingest pipeline → Azure Document Intelligence for OCR → LLM-based line-item normalization → 3-way match against POs and receipts → straight-through post to SAP, with exceptions routed to a review queue.
