How it works
How to use this BOM tool?
Creating a Bill of Materials takes four simple steps with Procol's free BOM tool:
Step 1
Add product details
Enter your product name, product code, and other basic details to start your Bill of Materials.
Step 2
Add components
List each component with its part number, description, quantity, unit of measure, and cost per unit.
Step 3
Calculate total material cost
The BOM generator automatically calculates the total material cost based on the components and quantities you enter.
Step 4
Download your BOM
Download your completed Bill of Materials in PDF or CSV format for sharing, printing, or procurement planning.

Built for everyone who touches a BOM
Procurement teams
Skip the back and forth. Get a clean, priced component list you can turn into supplier RFQs the same day.
Engineering & product teams
Keep every revision consistent. No more three versions of the same BOM floating in different inboxes.
Manufacturers and production planners
Know your material cost and quantity needs before the production run starts, not after.
Small business owners
Cost out your product like a manufacturer does, without buying manufacturing software to do it.
Single-level vs. multi-level BOM
The main difference is in the level of detail each BOM provides. A single-level BOM shows the direct components, while a multi-level BOM shows the complete product structure, including sub-assemblies and their components.
| Single-level BOM | Multi-level BOM |
|---|---|
| Lists only direct components | Includes components and sub-assemblies |
| Uses a flat structure | Uses a hierarchical structure |
| Easier to create and review | Provides greater detail and visibility |
| Best for simple products | Best for complex products |
BOM vs. bill of quantities (BOQ)
A Bill of Quantities (BOQ) covers the materials, labor, equipment, and work required for a project, while a Bill of Materials (BOM) lists the parts and raw materials needed to manufacture or assemble a product.
| Feature | Bill of Quantities (BOQ) | Bill of Materials (BOM) |
|---|---|---|
| Focus | Materials, labor, equipment, and project work | Parts, components, and raw materials |
| Commonly used in | Construction and engineering | Manufacturing and product development |
| Main purpose | Estimating costs, tendering, and project planning | Procurement, production, and inventory management |
| Cost details | Often includes unit rates and total costs | Usually focuses on quantities and specifications |
Integration of BOM data with ERP/MRP systems
BOM data can be integrated with ERP and MRP systems to keep product structures, materials, quantities, and inventory information in sync. This helps teams manage procurement, production planning, inventory, and material requirements from a central system.

Frequently Asked Questions About the BOM Generator
Quick answers about creating, costing and exporting a Bill of Materials.
A BOM generator creates a Bill of Materials from the information you provide, while BOM software is designed to manage BOMs throughout their lifecycle. BOM software typically supports version control, updates, collaboration, approvals, and integration with other systems such as ERP or procurement platforms.
An engineering BOM (EBOM) lists the components, parts, and specifications required to design a product. A manufacturing BOM (MBOM) reorganizes and expands that information to show the parts, assemblies, consumables, and processes needed to manufacture and assemble the finished product.
A BOM generator is a tool that creates a structured list of the materials, parts, and quantities needed to build a product, along with their costs. It makes that list easy to share with suppliers, production teams, and other stakeholders for pricing, planning, and procurement.
Enter your product details, add each component with its unit, quantity, cost, and supplier, then download your finished BOM as a PDF or CSV.
The BOM creator allows you to export your finalized BOM in PDF or CSV format. Use PDF if you require a shareable, professional-looking document, and use CSV if you require a spreadsheet-compatible document to analyze the BOM in systems like Excel or Google Sheets.
Yes! This BOM tool automatically calculates total material cost by multiplying each component's unit cost by its quantity as you enter it.
Yes. Procol follows enterprise-grade security practices to protect the information you share. Procol is SOC 2 Type II certified, ISO 27001 aligned, and GDPR compliant, with safeguards including encryption, access controls, network security, logging, and monitoring.
Businesses such as manufacturers, product teams, purchasers, engineers, and any companies that require documentation of the parts that are needed to build an item can utilize a BOM generator.
Depending on your requirements, a BOM can include:
- Product name and SKU
- BOM number and revision
- Effective date and preparer
- Production or batch quantity
- Part number and component description
- Unit of measure
- Required quantity and scrap
- Unit and total cost
- Supplier information
- Additional notes or specifications
After you finalize your BOM, you have the option to either generate material costs and print the BOM or export it as a PDF file or as a CSV file. You can further utilize your BOM from CSV for analysis in a spreadsheet or import it into any compatible inventory, manufacturing, and ERP systems.
