Bill of Materials (BOM)

A Bill of Materials (BOM) is a structured, hierarchical list of all the components, subassemblies, raw materials, and quantities required to manufacture or assemble a product. In manufacturing and product engineering, the BOM serves as the definitive record of what a product is made of and in what quantities — forming the basis for procurement, production planning, cost estimation, and inventory management. BOMs can be single-level (listing immediate components only) or multi-level (expanding all subassemblies to their constituent parts).

In AI and commerce contexts, BOMs are increasingly relevant as a data source for intelligent operations. AI-powered demand forecasting, supply chain optimization, and dynamic pricing systems all depend on accurate BOM data to trace how component shortages or cost changes propagate through finished goods. In digital commerce, configurable product catalogs and configure-price-quote (CPQ) systems rely on BOM logic to dynamically assemble valid product configurations and calculate pricing. As manufacturers build digital twins and AI-driven production systems, the BOM becomes a foundational data object that connects engineering, procurement, and commercial systems.
