Definition
Software that controls and optimizes warehouse operations including receiving, putaway, picking, packing, and shipping of palletized goods. A WMS tracks pallet locations, manages inventory at the pallet level, and directs material handling equipment. Pallet standards (dimensions, labeling, barcode/RFID) must align with WMS requirements for accurate tracking. Modern WMS platforms integrate with automated handling systems, conveyor sortation, and transportation management systems.

Radio Frequency Identification
A technology that uses electromagnetic fields to automatically identify and track tags attached to objects, including pallets. RFID tags embedded in or attached to pallets enable real-time tracking of pallet location, movement history, and trip count throughout the supply chain. RFID offers advantages over barcodes by allowing non-line-of-sight reading and simultaneous scanning of multiple tags. Major pallet pooling companies use RFID for asset tracking and inventory management.
Sortation
The automated process of routing palletized loads to specific destinations within a warehouse or distribution center based on criteria such as destination, product type, or priority. Sortation systems use conveyors, diverters, and scanners to identify and direct pallets to the correct staging lane or dock door. Pallet quality, dimensional consistency, and label readability are critical for reliable sortation. Non-standard pallets can cause jams and sortation errors.
Racking
The practice of storing loaded pallets on elevated warehouse racking systems (pallet racks). Racking places unique demands on pallet strength because the pallet spans across the rack beams with its load weight concentrated on the supported edges rather than distributed across a flat floor. A pallet's racking capacity is typically its most demanding load rating, and not all pallets are suitable for racking. Rackable pallets must be specifically designed and rated for this application.
Conveyor Compatible
A pallet design that meets the dimensional, weight, and structural requirements for reliable automated conveyor handling. Conveyor-compatible pallets must have consistent dimensions, flat bottom deck surfaces free of protruding nails, and sufficient rigidity to travel smoothly on roller or chain conveyors. Bottom board spacing and orientation are particularly critical, as gaps or misaligned boards can catch on conveyor rollers and cause jams.
