Nationwide · Headquartered in Columbus, Ohio
Warehouse & IBM i consulting, wherever your operation runs.
SIS is headquartered in the Columbus, Ohio metro and works with retailers, distributors, 3PLs, and manufacturers across the United States, on-site in your buildings and remotely on your systems.
A national footprint without a branch-office overhead.
On-site where it matters
Floor observation, design workshops, cutover, and go-live hypercare happen in your building. Our consultants travel to client sites across the country.
Remote where it is faster
Configuration, development, testing, data work, and IBM i support are delivered remotely, so you are not paying for travel that does not add value.
One team across your network
Multi-site programs get a repeatable deployment model and dedicated pods, so the tenth site benefits from everything learned at the first.
Our programs span single buildings and multi-site networks. Our Manhattan Active WM recovery, for example, brought 13 fulfillment centers live on a repeatable deployment model, and our IBM i work supports retail platforms whose stores and warehouses span the country.
Operations we work with across the U.S.
Retail and e-commerce fulfillment
Omnichannel DCs, store replenishment, direct-to-consumer fulfillment, and peak-season readiness.
Third-party logistics (3PL)
Multi-client warehouses that need flexible layouts, client onboarding, and billing-ready systems.
Wholesale and distribution
High-volume distribution centers balancing case, pallet, and each picking across channels.
Manufacturing warehouses
Inbound material flow, line-side replenishment, kitting, and lot and serial traceability.
IBM i shops of every size
Retailers, distributors, and manufacturers running core ERP and merchandising systems on IBM i.
New and relocated facilities
Greenfield DCs, network changes, and expansions driven by growth, reshoring, or nearshoring.
Every SIS service, in every state.
Rooted in Central Ohio since 1990.
