Jonathan brought OpenBOM to Tomcar to improve and formalize the agreements the company has with manufacturing partners. “I absolutely love that OpenBOM lets me share accurate, complete BOMs with vendors, partners, customers, my colleagues in Israel, and so many more.”, says Jonathan. “It is great for my team and great for the company. Simply put, before OpenBOM, we did not have a final BOM that was accurate or easy to share”, he says, “We needed a full product BOM which OpenBOM delivered!”

“I did not anticipate the overall benefit of the Solidworks integration” he says. “It was a big WOW! moment. Since then the scope of what we put in OpenBOM has grown. We can control more information, specifications,and requirements. OpenBOM forces adherence to a process!”

“Initially we settled on OpenBOM as a logical extension to our 3D design platform, Onshape. We saw the opportunity to leverage all metadata in Onshape but needed an organized way to bring it to the company (many of which were not engineers) for production. With OpenBOM we get the very reliable Onshape integration AND the ability to add and extend the data set as it flows through our company”

“This time last year I personally spent 5 hours per week on BOM maintenance. It’s now 10 minutes a week. We see that same improvement with many of the lead engineers on the team. OpenBOM frees the team to do the other things that are important.”

“Getting our BOMs out of Solidworks in Excel was hard. We would add some non-modeled items like hardware then have to manage all those additions individually each time we updated the Excel from Solidworks”. Using OpenBOM with SolidWorks and PDMWorks is much much easier, he says.
“OpenBOM easily manages and tracks our part numbers” he goes on to say, “something as simple as finding where a part is used is easy with OpenBOM’s where-used command; not having to open our CAD and look for a part is a huge time-saving.”

Garrett Rini
“One thing that was attractive was the low barrier to taking us several steps further than Google sheets. We could import directly from Solidworks, an existing Google sheet, or just type in data. OpenBOM functions the way we would expect it too.” says Garrett.

Eric Herms
“Steve and his team have extensive design and manufacturing skills and went right to the core of our implementation needs. Offering their expertise whenever we needed it and providing support with fast response times. The experience has been vital to our success with OpenBOM and we are excited to bring this new software to our organization”.

Ray Chen

“We like how we can create an M-BOM structure that correlates with our processes. Organizationally, Excel cannot do Flatten BOM. Flatten BOM is crucial to our production processes so we can determine exact quantities. In our process, we use the OpenBOM multi-level features to create an MBOM, then, we create a mid-level assy and organize items under it. We like how we can restructure the BOM. OpenBOM works for manufacturing much better than excel.”

“OpenBOM allows us to build a complete master BOM. Each and every item which goes into our product is in the BOM. That includes every component on every PCB, every Fusion 360 CAD designed part, and every off-the-shelf item we buy from a local supplier, we track it all in OpenBOM. Cost is very important to us. We track all line item costs and roll them up to the BOM level. Using custom formulas even allows us to keep track of sales pricing for different customers in multiple currencies, OpenBOM makes that easy to do.”

“We just moved into an expanded facility and needed to quickly update and revise our Bill of Materials process and methods”, says Jeff Podhajsky, Vice President of Operations at Grand Craft Boats. “Our old system just wasn’t able to handle our growth. We bought OpenBOM because it was the best fit for our company and we’re extremely surprised at how quickly the OpenBOM team put together the onboarding training for my team”.

What Is a Bill of Materials (BOM)

What Is a Bill of Materials (BOM)

The bill of materials software is something that often considered a simple thing. After all, what can be complex in a list of parts? However, as we can see in practice, manufacturing companies are usually underestimating the complexity and fail to manage it properly. BOM engineering is a complex discipline requires sophisticated data management and you’re trying to avoid it, the results can be brutal and painful. The results are usually very painful and coming faster than you can think – missed components, wrong cost estimation, delayed product deliveries, and frustrated engineers and customers running around trying to figure out where is the last and most updated bills of materials. At OpenBOM, we believe in openness and simplicity as the main drivers to help companies to get up to the speed with data management science behind Bill of Materials. It should be easy to start using OpenBOM and discover how to do it step by step. The Bill of Material is a structure representing all items needed to make a product. Depending on the product and business it includes a different level of details about how the product is engineered, manufactured, assembled, sold and maintained. Every engineering and manufacturing business should be concerned if parts and assemblies, as well as any other related data, are not managed properly.

What should be the content of the Bill of Materials?

Very often companies are asking – what to include in the BIll of Materials? A very simple answer to this question is EVERYTHING. The idea of not having something in a BOM is bad and to hope that you will remember what is needed is a recipe for disaster. Very often, we’ve been asked about what is a typical data set of the Bill of Materials. Here is a quick summary of what I think is absolutely essential.

Key Items and Elements of Bill of Materials

Key Items and Elements of Bill of Materials 

Part Number: This is a unique string that identifies every single component in the product. Not all part numbers are the same. You probably heard about OEM, Manufacturing, Suppliers and many other part numbers. Those are additional pieces of information. You might not use all of them. But, to have a unique Part Number for every single item is a must to have to keep things organized. Description: It usually gives the organization a simple way to look at the details about parts and components. Used for search, simple identification Description is not unique and must not be used to reference parts for any purposes except human interaction. Part Number is used for everything else. Part Name: Names make it easier for organizations to track components. Many systems have internal names with specificity useful to Operations, Test, and Engineering teams. A separate nomenclature might be with customers in Sales organizations. Unlike part numbers, part names aren’t necessarily unique. Consistent use of part names like connector, adapter, and cable, can help keep everyone on the same page. Unit of Measure: A very important piece of information that helps to identify how to measure the quantity of the part. Type (s): Usually absorbs the different types of information to classify part of help to identify how to manage the part. Organizations can apply multiple types to classify parts and how data about part can be processed. Revision and Phase: This is used to identify the level of maturity and specific changes. Companies are using various practices when creating new part numbers of revise existing parts. In addition to these parameters, organizations are usually including information about the manufacturer, suppliers, cost, and other pieces of data in BOMs.

Part vs Usage of the Part.

The information I mentioned above is usually the same about the item (part, purchased assembly). However, another group of information is typically included in BOMs and it represents a specific part usage.

  • Quantity: it is the ultimate way to say how many pieces of the part you need in this product. Note, in some cases (for instance BOM), quantity can be only calculated.
  • Reference Designator: Typically used in the electronic Bill of Materials usually represents a uniquely identified instance of the part (assembly).
  • Location: It is typically used in mechanical BOMs to differentiate between instances of the part/ assembly.


A very important element of the Bill of Materials. Effectivity is usually representing specific characteristics saying if a part (or assembly) can be used and under what conditions. There are different types of effectivity – date, configuration, serial number.

Configurations, Configured vs Resolved BOM

Last, but not least piece of information is related to complex products having multiple configurations. A BOM that contains information about multiple configurations usually called “configured BOM” and the BOM that represents information about a single configuration is called resolved.

SIngle-level, Multi-level, Flattened.

A list of components represented as one level is usually the basic way to plan the BOM. However, components are connected into assemblies and those usually have sub-assemblies. This is a simple single-multi-level structure. A flattened BOM is a report that summarizes the usage across multiple levels.
