Customer Stories Yoav KosterCo-FounderFF Robotics “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.”Learn MoreGarrett RiniLead Mechanical EngineerFlyPyka“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.Learn MoreHeather HeathBird Gard BuyerBird Gard“I love how I can easily add a property, as many properties as I need, to manage costs and other information about Bird Gard items, our existing system just could not do that.”“For example, OpenBOM can easily manage both an item’s Manufacturer Part Number and Supplier Part Number. I just add a column for each number and another for the URL link to the vendor’s product page, it’s that easy.”Learn MoreAlex WamainProducts Mechanical Design EngineerPuro Lighting“With OpenBOM”, We can quickly create a new SKU for a customer. OpenBOM reduces cycle times by allowing us to easily reuse an existing BOM, make a few changes, and have an entirely new BOM SKU ready to go to manufacturing.For example, we recently had a requirement for a new ballast enclosure based on an existing design, we easily reused the existing OpenBOM to create the new product.The entire process to reuse a product BOM went from one hour to 5 minutes.”Learn MoreHari PoluOKOS FounderPVA TePla OKOS“It works great! OpenBOM gives my team what they need, without the overhead of large, legacy, systems”, he adds. ”Ease of use is what OpenBOM is all about.” We don’t have an IT department; we are just engineers - OpenBOM doesn’t need an IT department.”Learn MoreKenyon WhetsellDirector of Mechanical EngineeringNexa3D“As the Nexa3D products matured we soon had a BOM administrator dedicating 20 hours a week to maintaining Excel BOMs. With OpenBOM we have no single admin. OpenBOM is largely self-sufficient, no dedicated IT person is needed. It just works.”“Looking back to the decision to buy OpenBOM over two years ago it was rather simple. We needed a solution with low capital investment. SAP and Oracle were out as they require full-time admin. We were lean and agile and wanted a BOM solution that would grow with us and suited to our company. No overhead of a complicated system”.“We looked ...Learn MoreHannah RedrupR&D Hardware EngineerDendra Systems“OpenBOM helps our engineering team design and maintain a cross-functional design and deliver the information needed to my (internal) customer.Before OpenBOM, we didn’t have any systems integration. After a change, many separate BOMs had to be manually updated in several places, OpenBOM took our systems process to the next level giving us an integrated process from design to manufacturing.We selected OpenBOM for many reasons, excellent Fusion 360 integration, simple and easy import, and export to leverage our legacy data, and of course, the cost and customization to meet our ...Learn MorePaul BlaylockOwner/Principal EngineerBlaylock LLC.“OpenBOM is a central feature of my business that allows me to work with many different engineering tools sets, adapt to various customer requirements, and craft and maintain a variety of deliverables; all necessary to meet the needs of each specific customer.OpenBOM’s item master catalog design lets me take a database design approach to components and properties. I like how I can organize my items and BOMs in much the same way as the physical parts, by category, vendor, availability, etc.I literally use OpenBOM to master items and output a BOM exactly in the format the customer ...Learn MoreDag BrændCOOVital Things“I was looking for a system that could hold complex BOMs and revision, control them in a sensible way. I have a lot of experience with large, expensive, cumbersome ERPs like SAP and others, I knew these big traditional systems were not going to be a fit at my company.”“We looked at many other systems, while most contained the basic logistical features we needed, none of the alternatives focused on the hierarchical BOM and revision control that was required by our industry.”“I needed an alternative and OpenBOM fit my needs exactly.”Learn MoreBill ThomasOperations ManagerFascia’s Chocolate“OpenBOM is so much simpler than Excel. As material costs have been changing so much lately, it's comforting to know that when I change an ingredient cost in one place, it updates in all of our product recipes.”“We love how OpenBOM rolls up the cost of all the ingredients to the top-level finished product.”Learn MoreCraig ZerwasEngineering & Operations Managerrf IDEAS“Before buying OpenBOM, our CMs had to go to many places to find the information needed to manufacture and build our products, or we had to find it for them, a time-consuming task, especially with revisions and ECOs.”“Now, with OpenBOM, we simply add the CM to our Team and share all drawings, Multi-Level BOMs, item definitions, ECOs, specs, engineering docs, and more all through OpenBOM.”“Everyone absolutely loves the where-used operation in OpenBOM. You just can’t do a where-used operation in an Excel BOM. It is impossible.”Learn MoreEric ShnellCo-Founder and CEOCraitor“When we rolled out OpenBOM we just installed it and threw a ton of data at it. I know we would have benefited from formal onboarding but we just needed to get a BOM now - and we did!”“The OpenBOM team later helped me smooth over a few rough spots in my process”, he says.“The pre and post-sales support from OpenBOM is outstanding. The team at OpenBOM are experienced engineers and manufacturing folks and it shows.”“As our process has matured we are finding even more benefits with OpenBOM. As a company, we have to be fast and flexible, we do all the work ourselves, and ...Learn MoreEthan SkuttMechanical EngineerKuva Systems“Something we didn’t see coming with OpenBOM is the benefit to others in the company who consume engineering and BOM information. We have non-technical people using OpenBOM to better understand where a particular item is used, how many of an item exists in a sub-level BOM, or any other item usage information, all without taking time from the Engineer.”“OpenBOM is used by the entire team at Kuva Systems and saves us many hours every week in BOM and inventory management. We understand costs and gaps and our inventory in nearly real-time.”“Simply put, we have a better BOM.”Learn MoreIvan AristovMechanical Design EngineerHive Lighting“Before OpenBOM, we managed all products in a single Google spreadsheet. We had one large document for ALL BOMs, dozens of tabs, some dupes, some tabs had several products…..”“Another file was the Item master. I had to jump from one Google doc to another to ensure correct information when making even the smallest change.”“OpenBOM brings organization and reliability to our data. It’s an interlinked system that allows changing details about one part in one place and it is updated in every BOM.”As you can imagine, a modern lighting system has a lot of parts. “We...Learn MoreAnne-Lyse MillerSupply Chain ManagerMechasys“We started with Excel which met our needs for a while, but later as we matured and moved towards manufacturing, it became very messy”, she explains. “Our product is compact and contains a variety of engineering and component disciplines. We have optical, mechanical, electrical, off-the-shelf components designed for manufacture both in-house and by outside suppliers,” she says.“My team took the time and looked at a lot of alternatives before selecting OpenBOM”, she explains, “from the super inexpensive to the extremely complex, OpenBOM was the right choice for us.”...Learn MoreJonathan DroriLead EngineerTomcarJonathan 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!”Learn MoreJohn EllerbrockPresidentGates Underwater Products“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!”Learn MoreEivind EgelandMechanical EngineerCurrence Robotics“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”Learn MoreFortune 500Head of EngineeringFortune 500 Global Consumer Electronic Manufacturing 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.”Learn MoreEric HermsPorts Systems and Services division Materials ManagerABB“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”.Learn MoreRay ChenManaging EngineerGaius Automotive“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.”Learn More read all reviews

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.

OpenBOM Bill of Materials core elements are represented using the Reference-Instance model and described by the following picture. You can see references (items) and their instances combined into parent-child relationships. OpenBOM provides a super-efficient and easy-to-use user interface to view, control, and collaborates around the Bill of Materials.
