# Recipes (Bills of Materials)

> Define what goes into the goods you make, so producing them updates stock correctly.

A **recipe** (or bill of materials) lists the **raw materials** that go into a
**finished good**. Recipes are for businesses that *make* what they sell — a
bakery turning flour and sugar into bread, or a kitchen assembling dishes.

<Note>
  Recipes are part of the **Recipes / BOM** feature. If it's not in your sidebar,
  your plan may not include it — see
  [Subscription & licensing](/guides/billing-addons/subscription-and-licensing).
</Note>

## Before you start

Set up your products with the right [product types](/guides/catalog-inventory/products#product-types):

* The ingredients should be **Raw material** products.
* The item you produce should be a **Finished good** product.

## Create a recipe

<Steps>
  <Step title="Open Recipes">
    Select **Recipes** from the sidebar.
  </Step>

  <Step title="Choose the finished good">
    Click **New recipe** and pick the finished-good product it produces.
  </Step>

  <Step title="Add ingredients">
    Add each raw material, the **quantity** used, and its **unit** (e.g. grams,
    litres, pieces).
  </Step>

  <Step title="Set the yield">
    Specify how many units of the finished good one batch produces.
  </Step>

  <Step title="Save">
    The recipe is ready to use for production.
  </Step>
</Steps>

## How recipes affect stock

When you record production from a recipe, TillBiz **reduces** the raw-material
stock and **increases** the finished-good stock — keeping both accurate without
manual adjustments.

<Tip>
  Recipe costing rolls up the cost of ingredients into the finished good, so you
  can see the true margin on items you make yourself in your
  [financial reports](/guides/reports/sales-and-financial).
