Third-party logistics provider running 110+ distribution centers and 18M+ sq ft of warehouse space, with its own PRISM warehouse management system, IT solutions, and asset-based transportation across the US and Canada.
Warehouse Services, Inc. (WSI) is a third-party logistics provider founded in 1986 that operates warehousing, distribution, and transportation under one roof. The physical footprint is substantial: more than 110 distribution centers totaling over 18 million square feet of warehouse space across 19 US states and 2 Canadian provinces, supported by an asset-based fleet of 900+ trucks and 5,000 trailers. The company employs approximately 4,500 people and has averaged 16% annual growth since inception.
On the software side, WSI runs its own proprietary warehouse management system, PRISM, which handles inventory management across the network. An internal IT Solutions group builds and maintains the technology supporting supply chain operations, spanning warehouse management systems, supply chain technology, and inventory management. That combination of owned WMS software and owned physical infrastructure - warehousing, distribution, value-added services such as kitting and sequencing, contract manufacturing, and transportation - means engineering work sits close to live operations rather than a separate tooling layer.
Operations span automotive, consumer goods, food, pharmaceutical, and chemical verticals, each with distinct handling and compliance requirements, and the customer base is described as blue-chip. The company holds ISO 9001:2015 and ISO 45001 certifications, is a Certified Women Business Enterprise (WBE), and carries an EcoVadis bronze certificate for sustainability practices. Stated operational focus areas include perfect order fulfillment and efficiency improvement.
