# OPTIS Color Swatch's Pricing | Changing Shopify Plan

# **What happens when your Shopify plan changes?**
OPTIS Color Swatch uses a **pay-as-you-grow pricing model**, meaning your app plan is linked to your Shopify plan.
### **How it works**
* You pay for OPTIS based on the Shopify plan you have **at the start of each billing cycle**.
* If your Shopify plan **changes during the cycle**, nothing happens immediately.
* At the **end of that billing cycle**, we check your **current Shopify plan**.

### **What you need to do**
* If your Shopify plan is **different** from the one you originally paid for, you’ll be asked to **approve a new app subscription** that matches your new plan.
* You’ll have **7 days** to approve it.
* During this 7-day grace period, the app **continues to work normally**.

### **If you don’t approve in time**
* After 7 days, the app will be **temporarily disabled**.
* Your setups are **not deleted**.
* Once you approve the new subscription, **everything is restored instantly**.

### **Example**
You start the billing cycle on **Shopify Basic** and later upgrade to **Shopify Advanced**.
At the end of the cycle, you’ll be asked to approve the OPTIS plan for **Shopify Advanced**.
You have **7 days** to approve before the app is disabled.

### **How charges work when you change your Shopify plan**
**👉 If you upgrade your Shopify plan**
* You may need to pay an **outstanding amount**.
* This amount is the **difference between your new plan price and your original plan price**.
* The charge is issued **by Shopify** and appears on your **Shopify bill**, **not** in the OPTIS app bill.

**👉 If you downgrade your Shopify plan**
* No extra charge is applied.
* The price difference will be shown as a **discount amount** on your app bill.
