What industries does Quantity Supply serve?

Building-materials and industrial distribution, with a focus on segments that quote large, multi-item orders at customer-specific pricing — plumbing supply, lumber and building materials, and electrical distribution among them. Under the hood it's industry-agnostic: it matches requests against whatever catalog and pricing you load. But it's built for the realities of construction-adjacent wholesale — tiered pricing, kits, substitutes, multiple branches, and the ERPs these companies already run.
