Pennsylvania Facility Turns its Sorter into a 24/7 Revenue Engine

A continuous induction system built for 24/7/365 performance
Through November 2024 and December 2025, a parcel facility in Pennsylvania deployed four InductOne automated induction systems from Plus One Robotics. The units were installed directly into the facility’s existing sorter infrastructure, eliminating the manual handoff between workers and the sortation line. Notably, they mounted seamlessly into the induction zone without requiring additional footprint or new equipment.
InductOne delivers a constant, high-density stream of packages into the sorter 24 hours a day, seven days a week, 365 days a year. Manual induction is governed by shift schedules, breaks, and headcount availability, whereas InductOne runs continuously. This decouples sorter performance from workforce constraints.
At-a-Glance
- Facility: Pennsylvania
- Deployment: 4 Plus One Robotics InductOne machines
- Installed: November 2024 (2), December 2025 (2)
- Application: Parcel induction
- Peak Throughput Gain: +8% at peak
- Annual Volume Value: Up to $2M/year per sorter
The sorter was always the most expensive thing in the building—and we were only using it when we had enough people standing in front of it.”

The hidden cost of a sorter that only runs when people do
Manual induction had capped the facility’s sorter utilization well below its theoretical capacity. Workforce factors such as staffing variability, breaks, and shift changeovers left the sorter operating at 40–70% of its designed throughput.
Despite this underutilization, sorters continue to incur depreciation and maintenance costs regardless of output. Every hour below capacity represents unrecoverable revenue.
The team recognized the constraint wasn’t the sorter—it was the process feeding it. Manual induction ties throughput directly to labor availability, exposing operations to wage pressure, turnover, and absenteeism. The sorter was always ready. The upstream process was not.
A case every parcel operation should see
The impact was immediate and measurable. With four InductOne systems in operation, the facility achieved an 8% increase in peak throughput. This gain required no additional footprint and no increase in headcount—just better utilization of existing assets.
Automation didn’t just replace a manual step—it unlocked latent capacity that already existed within the sorter.
Labor dynamics reinforce the value:
- High-turnover environments (up to 50%) drive recurring training costs (~$2,000 per employee)
- Annual training costs can reach ~$50,000
- Manual induction tops out around 2,250 parcels per hour (PPH)
- InductOne can achieve burst rates up to 2,800 PPH
- Estimated labor savings: $140,000 per cell annually
The financial model compounds quickly. A 1% increase in annual volume enabled by automated induction can generate up to $2M per year per sorter in incremental profit. This is high-margin throughput enabled by removing a bottleneck—not adding new infrastructure.
Key Outcomes
For any operation running a high-capex sorter on manual induction, the takeaway is clear: automation isn’t just about labor reduction—it’s about reclaiming stranded capacity and turning it into revenue.
