# What is invoice exception handling?
Invoice exception handling manages invoices that fail automated processing due to discrepancies or issues. Common exceptions include: (1) Missing PO Number - invoice lacks purchase order reference; (2) Price Variance - invoice price exceeds PO price by threshold; (3) Quantity Mismatch - invoiced quantity differs from received quantity; (4) No PO Match - invoice cannot be matched to purchase order; (5) Missing Receipt - goods not yet marked as received; (6) Duplicate Invoice - invoice number already processed; (7) Low Data Confidence - OCR extraction has low confidence scores. Exception workflows: automatically identify and categorize exceptions, route to appropriate resolver (buyer, AP clerk, manager), provide context and tools for resolution, track resolution time and bottlenecks, learn from resolutions to reduce future exceptions. Goal is to resolve exceptions quickly while maintaining control, using AI to predict and prevent common exceptions.
