Bill of Materials (BOM) Software for Manufacturing
Take Control of Your BOM — From Engineering to Production
Stop managing bills of materials in spreadsheets. With Fraction ERP, you can build, manage, and control multi-level BOMs with full visibility across engineering, purchasing, and production — all in one system.

What is a Bill of Materials (BOM)?
A Bill of Materials (BOM) is the structured list of all components, materials, and sub-assemblies required to manufacture a product.
It defines:
- What you need to build a product
- How those components relate to each other
- The quantities required at each level
In manufacturing, the BOM is not just a list — it's the foundation of your entire production process.
Without accurate BOMs:
- Production planning breaks down
- Costs become unreliable
- Material shortages increase
- Engineering and operations fall out of sync
Why BOM Management Fails in Most Businesses
Many manufacturers still rely on spreadsheets or disconnected systems to manage BOMs. This leads to:
Version Confusion
Teams working from outdated revisions with no single source of truth.
Costing Inaccuracies
No real-time visibility of material or labour cost changes.
Engineering vs Production Disconnect
Changes aren't communicated effectively between teams.
No Visibility of Sub-Assemblies
Complex products become impossible to manage without structure.
Manual Processes
Time wasted updating, copying, and fixing BOMs by hand.
What Great BOM Software Should Do
To support real manufacturing environments, BOM software must go beyond basic lists.
