3 Way Matching in Accounts Payable: When Control Becomes the Bottleneck
Three way matching catches discrepancies perfectly. But when exception queues start representing half your invoice volume, you haven't failed at control—you've outgrown detection-only systems. Here's what breaks and what's evolving.
