Bill Of Material Format

What is a Bill of materials?

A list of detailed data sources used in manufacturing a product is known as a Bill of materials (BoM). It is a comprehensive list of the components, raw materials, and instructions. BoMs include the information needed to manufacture, build, or repair services or products.

The list is not limited to the components. BoMs also contain the quantity of each element to produce finished goods. You can have multiple BoMs for a single product if it has a variant by colour, design, size, and other metrics. Bill of materials can also specify by-products, co-products, or scrap.

BOM structure

A Bill of Materials is organised in hierarchy, with the finished product at the top. It includes product code, part description, quantity, cost, and additional specifications. The most common ways to represent BOMs are single-level and multilevel BOMs.

Professional Bill Of Material Format

Single level Bill of materials

The single level BoM is a simple list that shows each assembly or sub-assembly. It is required for a product in the same quantity. It's a simple BOM to create.

This type of BOM, however, is unsuitable for complex products. If a new product fails, a single-level BOM complicates determining which part must be replaced or repaired.

Customizable Bill Of Material Format

Multi level Bill of materials

The multi level BoM approach requires more work but provides much-needed detail. The total material required is shown in a multilevel BOM.

The product structure describes the relationship between the parent and child products and the assembly and sub-assembly.

What are the types of Bill of materials?

The bill of materials (BOM) compiles all the information that goes into producing a finished product. Here is a list of types of BoMs:

Types Of Bill Of Material Format

Manufacturing Bill of Materials (mBoM):

Manufacturing bills of materials are commonly called mBoMs. It contains the parts and assemblies needed to build a complete, shippable product. Accurate records contain data that flows to all coordinated frameworks involved in requesting parts and building items.

The departments include
  1. Materials resource planning (MRP)
  2. Enterprise resource planning (ERP)
  3. Manufacturing execution systems (MES)

The mBoM is dependent on the accuracy of the number of parts ordered during the manufacturing process. The timetable for subsequent operations and departments can be based on the mBoM. Moreover, by aligning their timeframe, the purchasing team can arrange the best possible price from suitable vendors.

Engineering Bill of Materials (EBoM)

EBoM specifies the parts and assemblies constituted and designed by the engineering department. It emphasises more on designs of products than their manufacturing. Engineering BoM shows the functionality of a product through a technical and mechanical drawing.

Engineers use Electronic Design Automation (EDA) or Computer Aided Design (CAD) to develop the Engineering Bill of Materials. Most processes have multiple EBoM because the design is usually revised several times.

The engineering bill of materials also addresses the factors influencing the product's cost. The accuracy of Engineering BoM affects Manufacturing BoM. An authentic EBoM can improve purchasing decisions for required parts.

Configurable Bill of Materials

Industry dealing with highly configurable products and heavy machinery requires a configurable Bill of Materials. It includes the necessary components for designing and manufacturing an item per the client's specifications.

The CBoM can reduce the amount of work required to maintain product structures. Most configurable BoMs are driven by "configurator" software. A CBoM is a single product BoM that organises all component options by type and then lodges all variables beneath it.

What are the Essential Elements of a Good BoM?

Essential Elements Of A Good Bill Of Material Format

The crucial elements to create an accurate, detailed, and effective BoM includes:

BoM Level:

It represents the number or ranking of assembly and parts given in the hierarchy of the BoM. The BoM level intends to simplify things for all of the BoM's components.

BoM Notes:

The notes include additional information aside from the components of the BoM. Such data is crucial to building a product.


There should be a comprehensive and informative illustration of each material or part of the BoM. The purpose is to make it easier for anyone reading the document to learn about the material in depth.

Part Name:

Each part, material, or assembly must include a detailed and unique name. It allows anyone to identify that part without verifying it from other sources effectively.

Part Number:

Each part has a specific number. A unique number allows anyone involved in the manufacturing cycle to reference and identify parts quickly.


Keep track of the lifecycle stage of each part. For instance, you can use terms such as 'In Production' for production parts. Further, new parts that have not yet been approved can be classified as 'Unreleased' or 'In Design.'

Procurement type:

It refers to the method in which each part is obtained. Hence, you can know whether a part must be purchased off-the-shelf or manufactured according to project specifications.


Indicate how many parts are used in the bill of materials assembly.

Measurement unit:

The BoM should outline the measurement unit to measure the part or material. You can use terms such as 'each,' 'inch,' 'millimetre,' and 'ounce.' It ensures that exact quantities are procured and delivered to the shop floor.

How to create a Bill of materials?

It is essential to create an accurate bill of materials for product development. As your manufacturing process evolves, your bill of materials will go through multiple revisions before you see the finished product. It is not ideal to use a spreadsheet to manage your BoM.

Information will constantly need to be re-entered, exposing you to human error. It will be problematic to track what version of the document your staff is using. You need to establish a system that uses the latest technology for effective BoM management.

Create Customizable Bill Of Material Format

Manufacturers must use Enterprise resource planning (ERP) to create and manage BOMs. It enables you to streamline inventory management and reduce material costs. You can optimize material and reduce scrap quantity and production delay with ERP.

Why is BoM Important?

The acquisition of raw materials and assembling of the parts depends on BoM. One mistake could affect the group's productivity or individuals. An incorrect entry may lead to multiple revisions and loss of income.

Importance Of Bill Of Materials Format

The factors that represent the importance of BoM:

Product Specific: The Bill of materials contains all the details of the raw material. The quantity, name, number, and other specifications of waw materials enable its procurement.

All departments on one page: To ensure that product production or manufacturing runs smoothly, all departments must use updated BoMs. When you create an efficient BoM, all departments can know the status of the process in real-time, saving time.

Better Planning: Mapping projects in terms of time frame and number of people required for the project helps plan better. A detailed list makes a better plan for overseeing the project.

Improved Costing: Better planning provides the board with more accurate information. Orders must be processed efficiently based on factors such as time, materials, and directions. It results in better handling and cost reductions.
