Whether you’re building a machine, developing a product, or managing a construction project, the Bill of Materials (BOM) is one of the most critical documents in the process. It outlines every component, raw material, part, and subassembly required—ensuring nothing is overlooked and every cost is accounted for.

To help you streamline your production or planning workflow, we’ve compiled 43+ free Bill of Material templates in Excel and Word. These editable templates are designed for manufacturers, engineers, project managers, contractors, and anyone working with multi-component projects.

✔️ What Is a Bill of Materials (BOM)?

A Bill of Materials is a comprehensive list that details all materials, components, and instructions needed to manufacture or assemble a product. A BOM typically includes:

• Part names and descriptions
• Part numbers or SKUs
• Quantities needed
• Unit costs (optional)
• Supplier or vendor information
• Reference designators (for electronics)
• Notes or assembly instructions

Think of the BOM as the recipe for building a product—essential for purchasing, production, and inventory control.

✔️ When Should You Use a BOM Template?

Use a BOM template when:

• Planning or managing manufacturing workflows
• Coordinating engineering or construction projects
• Creating documentation for electronics or PCBs
• Designing new consumer products or industrial equipment
• Managing inventory or procurement
• Preparing quotes or cost estimates for multi-part builds

These templates ensure consistency, reduce manual errors, and keep your supply chain aligned.
