# How to Activate Shipduo Checkout Rates on Your Shopify Shipping Profile

> ⚠️ **Before you start — plan requirement:** This feature is available on **Shopify Grow (annual)**, **Advanced**, and **Shopify Plus** plans. If you're not on one of these plans, please **contact Shopify to enable it for you** before you begin this setup.
To show live Shipduo rates to your customers at checkout, you add **Shipduo as a shipping rate** in your Shopify shipping profile. The rate's own settings don't really matter — the important part is configuring the **backup rate**.

## Step 1: Open Shipping and Delivery
1. In your **Shopify Admin**, go to **Settings → Shipping and delivery**.
2. Find the **shipping profile** and the **shipping zone** (for example, North America / United States) where you want Shipduo rates to appear.

## Step 2: Add Shipduo as a Shipping Rate
1. In the shipping zone, click **Add shipping option**.
2. Choose to add a carrier / app rate, then select **ShipDuo (Rates provided by app)**.
3. The specific settings on this rate aren't important — just add it and save.
Once added, you'll see **ShipDuo (Rates provided by app)** listed in the zone with a **Calculated** label.

## Step 3: Set the Backup Rate (Important)
This is the step that matters. The **backup rate** is what customers see if third-party rates can't be displayed for any reason — so it's important to set it.
1. On the **ShipDuo** rate, click the **"..."** (more options) menu.
2. Select **Edit backup rate**.
3. Choose your backup rate option:
    * **Use Shopify default backup rates** (recommended) — calculated in real time from factors like location, carrier rates, order value, and weight.
    * **Define custom backup rates by order value**
    * **Define custom backup rates by item weight**
4. Click **Done**.

## Step 4: Save
Save your changes. Shipduo rates will now appear at checkout for that shipping zone.

## Troubleshooting
* **Rates not showing at checkout?** Confirm your plan supports third-party rates (Shopify Grow annual, Advanced, or Plus), that **ShipDuo (Rates provided by app)** is added to the correct profile and zone, and that a **backup rate** is configured.
* **Zone doesn't cover your customers?** Make sure the shipping zone includes the regions you ship to (e.g., United States).
* **Need help?** Chat with us or contact Shipduo Support.
