Inventory Sales Company

What Inventory Sales Company does

Inventory Sales Company ("ISC"), founded in 1972 and headquartered in St. Louis, Missouri, is a privately held industrial distribution business operating as a division of EFC International. The company stocks and distributes a full line of fasteners (ferrous and non-ferrous alloys), strut channel and accessories, sign hardware, stud welding equipment and consumables, shear wrenches and tension control bolting, industrial tools, and engineered fasteners for solar applications. It supplements distribution with two service capabilities: a 43,000-square-foot custom fabrication shop (structural welding, precision bending, in-house stud fabrication) and a worldwide sourcing program that connects customers to 50+ ISO-certified international suppliers with quality assurance, prototype approval, and independent lab testing. The company holds 600,000 square feet of warehousing across three Midwest facilities — St. Louis MO, Lenexa KS, and St. Elizabeth MO — supporting will-call, same-day pickup, and 24-hour "A" and "B" item shipment.

ISC's revenue model is anchored in hardware sales across fastener, strut, sign, tooling, and solar component categories, complemented by professional services revenue from custom fabrication and managed services revenue from global sourcing. Pricing is quote-based, with blanket orders and annual usage contracts available to enterprise customers; no public price list is disclosed. Go-to-market is sales-led and inside-sales driven, using phone, website quote forms, and physical will-call counters (including a 5,000 sq ft toolroom), supported by word-of-mouth referrals under the company's "The Customer is King" positioning. ISC also serves as a stocking distributor to other distributors and to OEMs across multiple verticals — construction (electrical, mechanical, steel erection), OEM manufacturing, solar energy, the sign industry, and MRO — typically on just-in-time delivery arrangements rather than transactional one-off orders.

The company operates exclusively in the Midwest United States under a regional distribution model with no disclosed global footprint, API or SDK surface, AI/ML technology stack, or external funding. It has no public management roster on its website, no disclosed revenue figure, and operates as a mature, family/private-equity-style industrial business embedded in a larger parent organization (EFC International).
