Abstract: Parcel sortation to postal sacks is one of the most labor-intensive, error-prone, and operationally costly processes in ecommerce fulfillment. This paper documents the multi-site rollout of an AI-driven robotic pick-and-sort system across a major 3PL logistics network. Deployed under a Robotics-as-a-Service (RaaS) model, the technology replaced manual sortation operations at three facilities and achieved a 75% increase in parcels per hour relative to fully manual operations, while reducing required headcount per sortation pod by 75%. Over a 4-year contract term, the projected total savings across the network reach approximately $15 million. Beyond the headline economics, this case surfaces a subtler argument: in a labor market where wages are volatile and worker turnover in sortation operations is chronic, the fixed monthly cost of robotics is not just cheaper—it is structurally more predictable. That predictability turns out to matter as much as the savings themselves.
