    A Bill of materials (or BOM) is a list of all the components used in producing an end product. It can be used for internal purposes, for example, to track what materials are needed for production and planning purposes, as well as for external purposes such as customer orders and sales orders.

    There are many different types of bills of materials, but they can generally be classified into six categories:

    Bill of Material Templates

    Bill of Material (BOM) Templates are pre-designed forms or spreadsheets that serve as a structured framework for listing and organizing the components, materials, and resources required to manufacture or assemble a product. These templates provide a standardized format for capturing detailed information about each item, including quantities, specifications, and sourcing details. BOM Blank Templates are used across various industries, including manufacturing, construction, engineering, and product development, to ensure accurate planning, procurement, and production processes.

    BOM Templates are designed to be flexible and customizable to suit the specific needs of a project or organization. They can be adapted to accommodate additional columns or fields based on specific requirements, such as cost calculations, revision history, or cross-referencing with other documents.

    By using BOM Templates, organizations can streamline their manufacturing or assembly processes, ensuring accurate planning, efficient procurement, and effective production. These templates provide a consistent format for capturing and organizing information about the components and materials, reducing errors, and improving communication within the production chain. They serve as valuable reference documents throughout the product lifecycle, facilitating inventory management, cost analysis, quality control, and future revisions or improvements to the product.

    Modular BOM Templates

    A modular BOM is a list of parts with their quantities and descriptions. It can be challenging to find a modular BOM template, but it is one of the most commonly used by companies today. This type is also known as an exploded view or exploded diagram.

    Engineering BOM Template

    The engineering BOM is used in manufacturing industries and shows a part number, quantity, and description for each item on your list. The engineering BOM usually has extra information because it’s based on engineering specifications rather than just simple product descriptions or numbers like in a modular BOM template.

    Manufacturing BOM Template

    This is used when you are creating a bill of materials for a manufacturing process. The purpose is to help streamline production and ensure that every item is accounted for in your inventory.

    Configurable BOM Template

    This type of template is used for easily customizable items, such as computer components or furniture pieces. The purpose is to allow customers to choose different options when purchasing these items so they can customize them to their liking.

    Equipment BOM Template

    This BOM Template helps track all parts needed to build equipment or machinery your company manufactures or sells. It also helps you keep track of spare parts needed in case something breaks down during operation.

    Benefits of using a bill of material

    Inventory management

    A bill of the material allows you to track inventory levels for each component in your manufacturing process. This can help you avoid running out of stock or having excess stock on hand that will have to be stored or discarded.

    Suppose you are using a BOM for purchasing. In that case, it also helps ensure that you only order the exact amount needed so that there are no excess costs associated with inventory storage and handling.

    Knowledge sharing

    A BOM makes it easy to share information about your products with other departments, such as sales and marketing. Your marketing department can use this information to help them create collateral (brochures, flyers, etc.) highlighting each product’s features and benefits. Sales representatives can use it when they’re talking to customers who want more information on a specific product or service you provide.

    Saves money

    By having an accurate BOM, you will know exactly what needs to be ordered from suppliers, so you will be able to save money ordering unnecessary items or overstocking items that may not sell quickly enough to warrant keeping them in stock at all times. You’ll also know how much inventory you need at any given time, which can save you money by saving on storage space and insurance premiums as well as reducing.

    Save time with the right data.

    The main benefit of using a BOM template is that it saves you time. It’s an easy way to ensure that your project has all the necessary components and is ordered correctly, so you can avoid wasting time by constantly checking back with other people.

    A clear overview of all product components

    When you’re working on a large project, such as an entire factory or store, it can be not easy to keep track of all the different components involved. A BOM template helps simplify this process by providing an overview of all the products involved in your project. You can see exactly what products are required for each step, how many units should be ordered, and from which supplier.

    Easy collaboration with multiple users

    Another benefit of using a BOM template is that it allows multiple users to collaborate on the same document simultaneously. This makes it easier for companies to manage projects with multiple departments involved in various stages of production or sales processes.

    What is contained within the bill of material?

    The following are some of the essential items that should be included in every BOM:

    Part number or SKU – The identification number for each item on the BOM. This can be any combination of letters, numbers, and symbols.

    Description – A short description of what the part does or what it’s used for in the finished product.

    Quantity How many of each part are needed to build one unit? For example, if you need two batteries to power your device, then you would enter “2” in this field.

    Unit cost – The price per unit for each part listed on the BOM. This information can be used to calculate the total cost for each unit produced using this BOM.

    Manufacturer name and part number – Any other identifying information about where to purchase each part listed on the BOM.

    Tips for making a bill of materials template

    The following are some tips for making a bill of materials:

    1. List all components and raw materials needed for production on one page.
    2. Include details such as quantity, material type, brand name, etc., along with each component/raw material listed.
    3. Use tabs or lines to separate different sections within the bill of materials template. This will make reading and understanding your data easy when you split it into categories based on functionality or other relevant factors.
    4. Use appropriate formatting styles such as bolding or highlighting to highlight important information such as serial numbers, model numbers, etc., so that users can easily find them when needed.
    5. Be sure that you are using the correct units of measurement (i.e., kilograms or pounds).
    6. Use a spreadsheet program like Excel or Google Sheets to create your BOM template with columns for each item on your list and any other information you want to include in your BOM, such as quantity and cost per unit.
    7. Keep it simple – Don’t try to include every detail in your template; include the most important information that will make it easy for people to use effectively.
    8. Make sure it’s easy to read – Use clear font styles and colors that make text easy on the eyes and easy to read quickly without having to strain or squint too much. If possible, use bullet points instead of paragraphs so readers can more easily scan through everything quickly without reading every word carefully.


    This template will be wonderful to use if you have a business that requires you to design bills of material. Also, this template is editable, so you can easily alter the text and modify the navigation. This template is available in Microsoft Word format, making it easy for you to change the font types.


    What is a Bill of Material (BOM)?

    A Bill of Material (BOM) is a comprehensive list of raw materials, components, assemblies, and other items needed to manufacture a product. It also typically includes quantities for each item.

    Why is a Bill of Material important?

    A BOM is crucial in manufacturing as it ensures that all parts required for production are available when needed. It helps in cost estimation, production planning, and inventory control.

    Are there different types of BOMs?

    Yes, there are various types of BOMs, including Engineering BOMs, Manufacturing BOMs, and Sales BOMs. Each serves a different purpose within the product lifecycle and production process.

    How is a BOM structured?

    A BOM is typically structured hierarchically, with the final product at the top, followed by sub-assemblies, components, and raw materials. It details the relationship and dependencies between different parts.

    What’s the difference between a single-level and multi-level BOM?

    A single-level BOM lists components and assemblies directly used in a product. A multi-level BOM breaks down components further into sub-components and their respective raw materials.

    How is the Bill of Material used in inventory management?

    BOMs help determine the raw materials and components required for production. This aids in inventory control, ensuring that enough materials are in stock, and helps in reorder point determination.

    Can a BOM change over time?
