How we cut picking errors by 40% for a Leeds distribution centre
A 20-person warehouse was losing money to picking errors and 8-hour weekly reconciliations. We fixed the process first - then added just enough technology to lock it in.

The business
Regional distribution centre in Leeds. 20 warehouse staff. High-volume picking operation handling multiple product categories with varying shelf lives.
The problem
Picking errors were damaging customer relationships and driving up costs. Weekly inventory reconciliation consumed 8 hours of management time. Staff turnover meant standard procedures were ignored. Shift handovers were chaotic.
The warehouse layout had grown organically over time with no logical structure.
The intervention
We started with a complete warehouse map. Every square metre, every shelf, every product location was documented and analysed. This revealed the root causes of the picking errors and inefficiencies.
Physical layout redesign
We reorganised the warehouse based on actual product movement data. High-velocity items moved to the most accessible locations. We redesigned workstations for better ergonomics, reducing unnecessary walking and physical strain on pickers. The new layout cut average pick path distance significantly.
Product segmentation and prioritisation
Products were segmented by multiple dimensions: velocity, size, shelf life, and batch characteristics. We introduced a clear prioritisation system that dictated which orders and which products took precedence at any given time. Pickers no longer had to make ad-hoc decisions about what to pick next.
The mini scanning system
We deployed a lightweight scanning system that enforces the correct picking sequence. The system does not allow pickers to deviate from the optimised route. It controls allocation priority based on batch numbers and Best Before End dates. This eliminated the most common source of picking errors: human decision-making under time pressure.
The scanning system is deliberately simple. It does one thing and does it well. It tells the picker where to go, what to pick, and in what order. No complex menus. No unnecessary features. Just forced compliance with the optimised process.
Continuous stock verification module
We built a verification module into the daily workflow. Every day, the system selects several random locations for the pickers to verify during their normal shifts. This is not a separate inventory count task. It happens naturally as part of the picking process.
When a picker arrives at a location flagged for verification, they confirm the physical stock matches the system record. Any discrepancies are flagged immediately and corrected on the spot. This prevents small errors from accumulating into major inventory discrepancies that require 8-hour weekly reconciliations.
The warehouse stays in good condition continuously, not just during periodic audits.

"Kamil found the leaks we knew existed but could not pinpoint. The changes stuck because they came from the team, not from a manual."

Why it worked
We did not start with technology. We started with the physical reality of the warehouse. We mapped it, understood it, and redesigned it based on how products actually move.
Only then did we add technology to enforce the new process. The scanning system and verification module work because they support a logical workflow, not because they are sophisticated software.
The team adopted the changes because the new system made their daily work easier and more predictable.
The services behind this result
Two independent tracks shaped this Leeds warehouse turnaround: the physical operations work came first, and a lightweight system locked it in.
