Overview
Client: Sunee Phungsub, Shallot Wholesaler
Location: Thailand
Facility: Private cold room warehouse
Storage Capacity: ~300–370 pallets of shallots (900–1,000 kg per pallet, totaling approx. 270,000–370,000 kg)
Shelf Life: 3 months
Challenge: Losses from expired stock, misplaced pallets, and inefficient manual processes.
Challenges
Sunee Phungsub, an experienced agricultural exporter and shallot wholesaler, operates a large cold storage facility where timely inventory rotation is critical. The business faced recurring issues:
❌ Stock Expiry Losses: Up to 75–100% of capital lost annually from unsold, expired shallots.
🔍 Lack of Visibility: Workers often couldn’t locate pallets, especially those close to expiration.
🚫 FIFO Breakdown: Newer stock frequently blocked older batches, disrupting proper inventory rotation.
📄 Manual Tracking Errors: Locations were recorded on paper, leading to delays and mistakes.
Solution
Locatematic’s Real-Time Location System (RTLS) was deployed using a combination of RFID-tagged pallets and UWB-enabled forklifts:
📡 Each pallet was tagged with an RFID tag, which integrates with the UWB system mounted on forklifts. This allows automatic identification of the pallet during every drop-in and drop-off.
📍 Forklifts equipped with UWB tags tracked all movements in real-time with 20 cm accuracy.
🧭 The system not only recorded exact location but also detected the vertical level at which a pallet was placed — critical in a warehouse that stacks pallets up to 3 levels high.
🧠 No manual input was required. The system automatically mapped and updated inventory positions as forklifts operated.
Results
✅ Reduced Inventory Losses: Over 80% of previously wasted stock was saved within the first product cycle.
🕐 Rapid Pallet Retrieval: Staff could locate the right pallet in under 1 minute.
🔄 FIFO Reinforced: The system guided workers to dispatch older pallets first using smart expiration alerts.
📊 Complete Real-Time Oversight: Sunee monitored every pallet’s position, height level, and status through an intuitive dashboard.
Testimonial
“Before Locatematic, I always feared missing stock before it expired. Now, every pallet is traceable — even on the top racks.”— Sunee Phungsub, Owner
