Why use a Put to Light?
Optimize and automate package selection
Our light-directed systems, whether configured as Put-to-Light or Pick-to-Light, use our cartonization software to determine the most cost-effective and space-efficient way to handle every order.
Many warehouses still rely on static packing rules or guesswork. often leading to oversized boxes, inflated DIM weight fees, and unnecessary packaging waste.
Cost and Labor Efficient
Our cartonization software automates box selection based on real-time SKU data, box sizes, product fragility, and carrier pricing rules. It ensures every shipment uses the best-fit box to minimize shipping costs and improve fulfillment efficiency.
Easy to Use
Our Put-to-Light hardware is rugged, reliable and intuitive for packers to use. It integrates seamlessly with your WMS and will provide step-by-step instructions to packers to make sure every packages follows precise shipping instructions.
Built-in Verification and Audit Trails
Every light-directed assignment is tracked in real time, giving supervisors visibility into what was picked, packed, and by whom. This built-in audit trail not only reduces the chance of errors but also makes exception handling faster and more transparent.
Whether you’re batching multiple orders or verifying high-value shipments, the system provides a simple layer of accountability without slowing down operations.
