How a Startup 3PL Raised Pick Rates From 40 to 150 UPH With AMRs
A high growth e-commerce 3PL reports picker rates jumping from about 40 to 150 units per hour after warehouse AMRs cut walking and boosted peak throughput 55%.

Volatile volume on a thin labor bench
The third-party logistics site serves a startup retailer whose order patterns swing hard with promotions and seasonality. Wage pressure and hiring gaps made it hard to staff pick paths that depended on walking, extra touches, and manual cart moves.
Leadership needed higher units per hour without missing service level agreements or paying constant overtime. Accuracy had to hold as throughput climbed.
AMRs with live floor visibility
The operator deployed autonomous mobile robots tied to a warehouse execution layer and dashboards that show throughput, labor, and order status in real time.
Associates stopped spending shifts pushing carts long distances. Robots carried goods to pick stations while people focused on value added packing and verification.
Integration with the existing warehouse system let the team scale robot count up or down as the startup customer forecast shifted.
- Model current pick paths and congestion hot spots
- Integrate robot tasks with the warehouse management system
- Train pickers on robot assisted stations
- Use dashboards to staff to daily order mix
- Add AMR capacity ahead of known demand spikes
Throughput and accuracy on the board
Before robots, the site averaged roughly 30 to 40 units per hour per picker. After go live, leadership reported a range of 120 to 150 units per hour, described as a 275 percent productivity increase in the public case materials.
Peak throughput rose about 55 percent, helping the team hit on time service levels when order volume spiked.
Pick accuracy improved as redundant walking dropped and the robot workflow added consistent checks at the station.
Lessons for US 3PL and retail fulfillment leaders
This documented deployment is not a Service Robot Co. client story. It shows how warehouse robot rental and AMR fleet deployment can absorb startup style demand swings without hiring for every peak.
Service Robot Co. selects autonomous mobile robots that fit your slotting and WMS, finances units on monthly programs, and services them through a nationwide network of regional service engineers.
