# Bill of Materials

> Define standard parts lists for recurring job types so every technician knows exactly what to bring.

A Bill of Materials (BOM) is a predefined parts list for a specific job type. Instead of manually selecting parts every time you create a work order, a BOM pre-fills the parts list based on the job category.

## Why Use BOMs

* **Consistency**: Every HVAC install gets the same parts, every time
* **Speed**: Technicians don't have to remember which parts are needed
* **Accuracy**: Reduces the chance of missing parts or billing the wrong items
* **Costing**: Pre-set costs mean accurate job estimates from the start

## Creating a BOM

<Steps>
  <Step title="Go to Inventory > BOM">
    Click **Add BOM** and give it a name (e.g., "Standard HVAC Install").
  </Step>

  <Step title="Add parts with quantities">
    Search your parts catalogue and add each part with the standard quantity needed for this job type.
  </Step>

  <Step title="Link to job categories">
    Associate the BOM with specific work order categories. When a job of that category is created, the BOM is suggested automatically.
  </Step>
</Steps>

## Using BOMs on Work Orders

When creating or editing a work order, click **Add from BOM** to pre-fill the parts list. You can still adjust quantities or add extra parts as needed.

## FAQ

<AccordionGroup>
  <Accordion title="Can a work order have multiple BOMs?">
    Yes. A complex job might need parts from several BOMs. Add each one and Vynta merges the parts lists, combining duplicates.
  </Accordion>

  <Accordion title="What if a part in the BOM is out of stock?">
    Vynta shows a warning when you add the BOM, indicating which parts are unavailable and where they might be sourced.
