Maxwell, Content Marketing Manager & Data Director, WinsBS Research:
“WMS accuracy is the backbone of fulfillment reliability. In our 2025 dataset of 220 U.S. warehouses, brands using WMS-driven pick routing improved same-day order processing by 41% and reduced mis-picks by 62%. When WMS is paired with OMS routing, multi-node fulfillment accuracy reaches 99.3%.” — WinsBS Research (sample: 220 U.S. fulfillment centers, 2025)
