Systems Integration Specialists (SIS), headquartered in Blacklick, Ohio, is a 100% employee-owned technology consulting firm founded in 1990. The company organizes its work into three core practices: Warehouse Strategy & Optimization (operational assessments, facility design, systems enablement and automation), IBM i Solutions (platform modernization, integration and performance work), and Project Delivery Solutions (program leadership, PMO design and project recovery).
SIS states it recently became a strategic partner delivering Infor's tier-1 cloud warehouse management system, adding capabilities such as voice and task automation, 3D warehouse visibility, and support for B2B, B2C and 3PL fulfillment operations alongside its existing work with other WMS platforms (Manhattan Associates, Island Pacific). The firm reports more than 1,000 consultants with an average of 15+ years of experience, and has been recognized on the Inc. 5000 list with 218% three-year revenue growth as of 2024.
SIS names several large clients by size and project rather than always by name: a $36B medical supplier (MAWM implementation), a $5B global fashion retailer (Island Pacific v19.1 upgrade), and Ascena/Knitwell Group (Locus robotics/AMR deployment). Its site does not explicitly confirm work with Infor OS or ION beyond the general WMS partnership.
