**Bill of Materials (BOM)** is a complete list of all items with corresponding costs and quantities that are required to build a product. BOM helps companies estimate material costs to plan purchases and reduce waste. It also helps users never miss a single thread, button, zipper, or tiny detail when manufacturing their products.

These steps will guide users to understand how to use the BOM Features.

To access the **Tech pack bill of material Page**, go to **Collection & Style \>** **Style** from the left bar menu.

- Select your created style and click **Tech pack \> B****ill of Material** on the style menu.

- The BOM page will display.

- To create the Bill of Material, you must select the final version card and the color of the style.

**Nb:** the **Version** that corresponds to the version of the Input Page on Design and Development in the version section.

1. **Check if a Colour is Added First**

   If no colour has been added to the style yet, the Bill of Material section will show a message: “Bill of Material is not available yet.” To generate the BOM, at least one colour must be added first in Style Details. Click Go to Style Details to add a colour.

   > [!NOTE]
   > If the final colour is not confirmed yet, add a placeholder such as TBC1, TBC2, or TBC3 so you can continue building the BOM now and update it later.

2. **Add a Colour in Style Details**

   In the Style Details page, scroll down to the Colors field. Click + Add Color to add a new colour option. For each colour, fill in:

   - Code – a short colour identifier (e.g. black)
   - Pantone Code – the Pantone reference number (e.g. 1234)
   - Name – the colour name (required field)
   - Description – optional notes about the colour

   You can also click Color Library to pick from saved brand colours. Once done, return to Tech Pack \> Bill of Material.
