10 Key Elements of a Bill of Materials

Are you curious about what is included in a bill of material? However, some people just create a BOM without having complete knowledge of it. So, here we are with this guide, this section will help you understand the key elements that a BOM should have. 

  • BOM Level: Imagine BOM levels as a family tree, for AV components. The higher the level, the more significant the part becomes. In this analogy, cameras can be likened to the “parents,” while cables are akin to the “children”, in this AV family.
  • Part Number: Part numbers are like unique names for AV gadgets. Just like how your phone has a unique model number, AV equipment, like projectors, gets its own special part number for easy identification, such as “AVP-1000.”
  • Part Name: It’s like the nickname of AV gear. Instead of calling it “Component X,” you give it a friendly name. For instance, a microphone could be called a “Condenser Mic – Model X.”
  • Phase: This shows where AV stuff is in its life story – whether it’s still being made, already built, or just getting fixed. A camera might be in the “Production” phase.
  • Description: Descriptions tell you what each AV thing does. For example, an HDMI cable’s description might be “HDMI Cable – 6 ft, Gold-plated connectors.”
  • Quantity: It’s just how many of each AV thing you need. If you’re setting up a meeting room, you might need 10 microphones.
  • Unit Measure: This indicates the measurement unit for each component, such as “each,” “meters,” or “pieces.” In AV, a speaker might be measured in “each,” while cables are measured in “meters.”
  • Procurement Type: This says if you’re buying AV things or making them yourself. Cameras might be bought from a store, while special cables might be made in your AV workshop.
  • Reference Designator: This assigns a label to each component for easy cross-referencing with schematics. In an AV BOM, a projector might have a reference designator like “P1.”
  • BOM Notes: Additional information, such as special requirements or compatibility notes, enhances understanding. For example, an AV BOM note might highlight that specific microphones are compatible only with designated mixers for optimal performance.

Types of Bill of Materials

Now that you’ve understood the major elements included in a bill of material, you should also be aware of the different types of BOM. Here we have listed for you seven types of BOM, with this you can understand what suits you best and go ahead with it and provide a better-detailed BOM to all your clients.
