Accessorial Charge Validation

The process of automatically checking and confirming additional freight charges—such as detention, liftgate, or residential fees—against contracted terms before payment. Traditionally, accessorials are a common source of billing surprises and disputes. With KNNX, accessorial charges are captured and validated in real time using smart contracts and shipment data, ensuring that only legitimate, agreed-upon fees are included in the invoice. This prevents overpayment, improves compliance, and maintains strong carrier relationships.
