Inventory accuracy is not just an operational metric, it directly impacts customer experience, fulfillment speed, and overall efficiency. For fashion retailers operating at scale, maintaining reliable stock data becomes increasingly complex as product references grow and e-commerce volumes accelerate.
That’s exactly the challenge Tendam set out to solve.
To address it, Tendam partnered with PAL Robotics to deploy StockBot, its autonomous RFID-powered inventory solution, at its logistics center in Illescas (Spain), in collaboration with ID Logistics.
From RFID implementation to a new way of managing inventory
Tendam’s journey started with RFID. As the company expanded its use of RFID across operations, new opportunities began to emerge. What initially served as a way to improve visibility quickly revealed its potential in logistics, especially in e-commerce environments.
“This project stems from the implementation of RFID at Tendam. As we continued to discover different use cases, we realized that we could also implement this stock-reading system in e-commerce operations.”
— Jose Andreas Alonso, RFID Product Owner at Tendam
What followed was a gradual evolution. Over the past three years, Tendam and PAL Robotics have worked closely together, starting with a proof of concept and progressively refining the solution for their warehouse conditions.
At the core of this collaboration was a simple but critical objective: improving inventory reliability.
When visibility becomes trust
Improving inventory reliability is not just about counting stock more often, it’s about being able to trust the data behind every operation. In fast-moving warehouse environments, even small discrepancies can have a direct impact on order preparation, stock availability, and ultimately, customer satisfaction.
As Tendam’s operations continued to grow, maintaining that level of accuracy became increasingly challenging. More references, higher volumes, and constant movement of goods made traditional inventory methods harder to sustain at scale.
StockBot introduces a different approach. Instead of relying on periodic manual counts, it enables continuous, autonomous inventory tracking. Moving through the warehouse, it scans stock daily using RFID, creating a constant stream of reliable data that complements the WMS (Warehouse Management System). One of its most valuable contributions is the ability to detect what would otherwise go unnoticed: items that are physically present but not registered in the system.
“Having an inventory that we can monitor on a daily basis helps us reduce preparation times and errors, while also enhancing the user experience.”

Better visibility translated into better operations
By improving inventory reliability, Tendam is able to reduce discrepancies, streamline order preparation, and respond faster to issues as they arise.
“Implementing the robot results in fewer incidents, faster order preparation, and ultimately higher quality for the end customer.”

At the same time, the insights generated allow teams to act more precisely, focusing their efforts where adjustments between theoretical and physical stock are truly needed. StockBot takes over repetitive inventory tasks, enabling staff to focus on higher-value activities such as analysis and decision-making.
“In the warehouse, we don’t see the robot as a replacement, but as a support tool that enables us to focus on higher-value tasks while it handles the most repetitive day-to-day tasks.”
— Marlin Arenas, Stock Management in ID Logistics
Implementing StockBot in the warehouse
Deploying StockBot required more than simply introducing a robot into the area.
Each warehouse has its own logic, constraints, and operational rhythms. That’s why the implementation process focused on adapting the solution to Tendam’s environment, from mapping the facility to defining routes, inventory points and charging stations.
This level of customization ensures that StockBot integrates seamlessly into the company’s operations,working alongside existing workflows without disruption. This way, the robot becomes not just a technology layer, but a natural extension of the operation itself.
A new standard for inventory in e-commerce
Tendam’s experience reflects a broader shift in how warehouses operate. As e-commerce continues to grow, inventory management is evolving from periodic, manual processes into continuous, data-driven systems. The combination of RFID and robotics makes this transition possible, bringing accuracy and visibility to a level that was previously difficult to achieve at scale.
“I think the main benefit of StockBot is that it provides continuous and automated inventory, allowing us to prioritize resources and be more efficient when identifying potential issues.”
— Jose Andreas Alonso, RFID Product Owner at Tendam
What started as an exploration of RFID capabilities has become a fully operational solution that delivers measurable impact across efficiency, accuracy, and customer experience, turning data into a reliable foundation for faster, smarter, and more scalable warehouse operations.
