What Onesource Distributors does

OneSource Distributors is a B2B broad-line distributor of electrical, automation, and industrial supplies operating as a subsidiary of Sonepar USA Holdings, Inc., part of the global Sonepar distribution group. Headquartered in Oceanside, California, the company serves customers across California, Arizona, and Hawaii through a network of 13 walk-in sales centers and two regional distribution centers (Fullerton and San Leandro). Its catalog spans 23+ product categories including conduit and wire, control and automation components, power distribution, lighting, enclosures, safety products, tools, welding supplies, solar products, and electric vehicle charging equipment.

The company's core technology consists of a B2B e-commerce website and the OneSource SPARK mobile application (iOS and Android), which provide account-gated pricing, online ordering, and digital account management alongside the physical branch network. It holds authorized distributor relationships with major manufacturers including Rockwell Automation (for which it is also an Authorized Service Provider), Siemens, Legrand, nVent Hoffman, and 3M. The company is a specialist in industrial automation products, particularly Rockwell's PLCs, drives, motion control, and HMI lines.

Revenue is generated through product mark-up on hardware sales to three primary customer segments: electrical contractors (commercial, residential, and solar installers), industrial end-users/OEMs/system integrators requiring automation and control products, and institutional buyers (education, government, healthcare). Pricing follows a login-gated trade/commercial unit-pricing model. Founded in 1983, the company operates with 251–500 employees under the privately-held Sonepar parent group.
