The brief
An AI document pipeline for a freight forwarder that reads every invoice and customs form, and only sends the doubtful ones to a person.
Meridian’s operations team spent their days re-typing shipping papers into the ERP. We built a back-end that reads each document with AI, checks every field against the shipment record, and queues anything uncertain for a person to confirm — with the reason shown.
