For every warehouse type
Whether you run a block storage facility, a racked warehouse, a cross-docking hub or a mixed operation — SLAPStack works with your existing setup. No infrastructure changes. No new forklifts. Just plug in TrackRack and gain full visibility from day one.
Do you really know what's happening in your warehouse?
Most warehouse managers don’t. Knowledge lives in drivers’ heads, measurements are done manually, and nobody has a live overview. SLAPStack changes that.
- From measurement to perfect storage— automatically: TrackRack measures every pallet in 3D while moving. The system knows exactly where space is available and stores goods optimally — no tape measures, no wrong freight costs, no wasted space.
- Always know where everything is — without searching: Real-time location of every forklift and pallet, AI-optimized routing and automatic bottleneck detection. Up to 51% faster order processing from day one.

Differences
Key challenges
Manual Warehouse Operations
High Personnel Costs
75 % of operating costs are personnel costs, significantly impacting ongoing expenses.
Lack of Qualified Workers
The growing shortage of skilled workers makes recruitment and operations more challenging, further exacerbating labor costs.
High Forklift Accident Rate
11% of forklifts are involved in accidents each year, leading to safety risks and additional costs.
Lack of Stock Transparency
There is no real-time visibility into stock levels, causing inefficiencies and potential stock
shortages.
Automated solutions solve those problems, but lead to the following other challenges.
Automated Forklift
High Investment Costs
Requires an initial investment of over 150,000€, making it a costly solution for many businesses.
Slow Deployment
Implementation and deployment take approximately 9 to 18 months, delaying the return on investment and operational benefits.
Little Flexibility
Automated systems often struggle to adapt to changing warehouse layouts, strategies, varying order profiles, or unexpected disruptions.
Fixed & Hierarchical Decision-making
processes, which limit flexibility and adaptability to dynamic warehouse environments.
SLAPStack tackles those problems, delivering the simplest and most flexible automation solution for block storage.
SLAPStack
Fast Implementation
All-in-one-Product that integrates fleet control, inventory management, and simulation enables setup in less than one week.
Optimized Order Processing

Frequently Asked Questions
Yes. TrackRack is a roof-mounted retrofit kit that works with any forklift brand and type. No modifications to the vehicle are needed.
A single TrackRack unit can be mounted in under half an hour. The full system, including Driver App setup and software configuration, is typically up and running within a day.
No. TrackRack requires no floor markers, no RFID tags, no ceiling infrastructure and no wiring. It works entirely camera-based.
Yes, absolutely. TrackRack works as a standalone solution. A popular use case is automated 3D load dimensioning, TrackRack measures every pallet automatically while the forklift moves. The data is transferred directly to your existing WMS/ ERP/ TMS via a REST API or VDA5050. No manual measuring, no wrong freight costs, no extra steps. You only add SLAPStack OS when you want full fleet control, smart routing, analytics features or autonomous vehicle integration.
Yes. SLAPStack OS offers a REST API that connects to all WMS, ERP systems, and TMS.
Yes. SLAPStack is fully GDPR compliant. TrackRack processes all camera data directly on the device — nothing is sent to the cloud. Only the relevant operational data (forklift positions, load dimensions, movement data) is transmitted to SLAPStack OS. No raw camera footage leaves the device. No personal data of drivers is stored or processed without consent. All data is processed and stored on servers within the European Union.
The Warehouse Assessment is a simulation-based analysis of your warehouse. We create a digital twin of your real layout and operations to identify bottlenecks, inefficiencies and savings potential, before you invest in any technology. The result is a clear, data-driven decision basis, fast, low-cost and without disrupting your day-to-day operations.
We recommend it if you want to: understand your current warehouse performance and where efficiency is being lost; plan a greenfield warehouse from scratch; change your layout, zones or storage strategies; optimize your inbound or outbound processes; prepare for full or partial automation.
The same digital twin powers both the Warehouse Assessment and SLAPStack OS. If you decide to continue with TrackRack or full automation, the integration is significantly faster, your warehouse is already fully modelled. Even if you decide not to continue, you still gain full value from the Assessment itself: Direct efficiency gains like bottleneck analysis, vehicle fleet comparison, storage strategy comparison, layout and zone comparison, and loading & handling strategy comparison, or digitalization & automation information like market overview of technology providers, ROI analysis, concept for transfer and buffer zones, scalability assessment. Either way, you gain, without risk.
Yes. SLAPStack OS supports hybrid fleet management — sending tasks to both manually operated forklifts equipped with TrackRack and autonomous vehicles via the VDA5050 standard.
SLAP stands for Storage Location Allocation Problem, the fundamental challenge every warehouse faces: where to store what, and how to find it again efficiently. Stack refers to stacking — the physical reality of most warehouse operations where loads are stacked on top of each other, making transparency and optimization even more critical.
A warehouse digital twin is a real-time virtual model of your physical warehouse. It captures the exact layout, storage locations, forklift positions and load movements — and mirrors them digitally in real time. With a digital twin you can: - See exactly where every pallet and forklift is - Identify bottlenecks before they cause delays - Test new storage strategies without disrupting real operations - Make data-driven decisions instead of guessing SLAPStack creates a digital twin of your warehouse automatically — using camera-based tracking on your existing forklifts. No sensors, no infrastructure, no rebuilding required.
In most warehouses today, staff still measure pallets and loads manually with a tape measure. This takes time, requires stopping the forklift, and leads to errors — studies show that 20-40% of shipments end up with wrong dimensions. Wrong dimensions mean wrong freight costs, carrier chargebacks and customer complaints. TrackRack replaces the tape measure entirely. The camera system measures every load automatically in 3D while the forklift is moving — length, width and height are captured instantly without stopping or manual entry. The result: accurate dimensions for every shipment, automatic data transfer to your WMS, ERP, or TMS, and zero measurement errors from day one.
Yes, but TrackRack is much more than that. Traditional RTLS solutions track vehicle or asset positions using RFID, UWB or Bluetooth tags — requiring infrastructure like ceiling anchors, floor markers or fixed readers throughout your warehouse. TrackRack does all of that and more, using only a camera mounted on your existing forklift. No tags, no anchors, no infrastructure. In addition to real-time localization, TrackRack also provides: Automatic 3D load dimensioning while moving, Label scanning and identification, AI-optimized driver routing via the Driver App, Live inventory overview, Integration with your WMS, ERP or TMS One device. One installation. Everything a traditional RTLS does — plus the features your warehouse actually needs.
