What is bill of materials software?
Bill of materials software lets you define every material, component, and sub-assembly that goes into a finished product, then uses that structure to calculate cost and track inventory. Stocksmith builds a BOM for each product, rolls up the true cost per unit, and deducts the right materials automatically every time you manufacture.
Can I build multi-level BOMs with sub-assemblies?
Yes. Stocksmith supports multi-level bills of materials—recipes within recipes—so you can define base mixes, components, or sub-assemblies once and reuse them across products. Costs and quantities roll up automatically through every level, which is exactly where spreadsheets start to break.
Do product costs update when my material prices change?
Yes. When you record a new purchase price for a material, every bill of materials that uses it recalculates automatically. You see updated cost per unit and margins straight away, so you can adjust pricing before rising supplier costs quietly eat your profit.
