About QC Supply

From its humble beginnings in a garage, selling livestock products to local producers in 1982, QC Supply has grown into an International distributor to farms, businesses and resellers worldwide.

Headquartered in Schuyler, NE, QC Supply is comprised of a call center, retail store and the largest of 3 warehouses. Other warehouses are located in Missouri and Oklahoma. The recent acquisition of Gillis Ag resulted in distribution sites in Iowa and Minnesota. A second retail store is located in Elkhorn, NE. All of these locations give QC a closer presence and an ability to more quickly serve customers.
