# Create a Commission Rule

> Override the global commission for a specific store, product type, or category.

> Charge a different fee for certain stores or products than your global commission.

## Overview

A commission rule overrides the global commission for a specific scope, such as a single store or a product category. When several rules could apply to a sale, the most specific rule wins. If no rule matches, the global commission is used.

Creating a rule is a two-step form: "Details" defines what the rule applies to, and "Commission" sets the fee.

## Step 1: Start a new rule

1. Go to "Settings" in the sidebar, then "Commissions".
2. Click "Create" in the "Commission Rules" section.

## Step 2: Define the scope

In the "Details" step:

1. Enter a "Title" so you can recognise the rule later.
2. Enter a "Code". This is a unique identifier for the rule.
3. Select the scope "Type":
   * "Store". Apply to specific stores.
   * "Product Type". Apply to specific product types.
   * "Category". Apply to specific categories.
   * "Store + Product Type". Apply to product types within specific stores.
   * "Store + Category". Apply to categories within specific stores.
4. Depending on the scope, select the specific stores, product types, or categories the rule applies to.
5. Click "Continue".

## Step 3: Set the fee

In the "Commission" step:

1. Select the "Type". Choose "Percentage" to charge a percentage of the order total, or "Fixed" to charge a set amount per order.
2. Enter the "Value". For a percentage, enter a number between 0 and 100. For a fixed fee, enter an amount for each store currency.
3. Set "Tax included" and "Shipping included" as needed. These work the same way as for the global commission.

## Step 4: Save

Click "Save". The new rule appears in the "Commission Rules" list and applies immediately to matching sales.

<Note>
  When several rules could apply to the same sale, the most specific rule wins.
