BOM Control: 7 Mistakes That Cause Cost Overruns

Small BOM errors create expensive downstream issues. Here are the most common mistakes and how to prevent them.

Common BOM mistakes include duplicate components, outdated revisions, and unclear units. Use one authoritative BOM source, lock revision history, and require approval for changes. Tie each BOM to active production orders so material demand updates automatically. Audit your top 20 assemblies monthly. This single habit often recovers margin faster than complex optimisation projects.
