# Will I get charged more when I change the plan?

We understand that your needs may change over time. Here’s what to expect when you upgrade or downgrade your subscription plan.

# Table of Contents

### I. Upgrade Plan

### II. Downgrade Plan

*📌 **Note:** Opus uses **Shopify’s billing system**, but operates on its own **30-day billing cycle**, which may not align exactly with Shopify's invoice cycle. Most app charges will appear on your **next Shopify invoice**.*

# I. Upgrade Plan
When you upgrade to a higher plan, Shopify will ask you to **approve the new charge**. Learn more about how Shopify handles app charges [here](https://help.shopify.com/manual/your-account/manage-billing/your-invoice/apps).

Once approved:
* You’ll immediately unlock all features of the new plan.
* All your existing data will remain intact.
* Your current recurring charge will be canceled and replaced with the new one.
💡* **If you upgrade mid-cycle**, a **prorated charge** will apply based on the remaining days in your billing cycle.*
#### Proration Formula:

|| Total = current_plan_cost + (new_plan_cost - current_plan_cost) × (remaining_days / 30)

#### **Example:**
* You're on the **Advance Plan** ($19.99).
* On Day 15 of the cycle, you upgrade to the **Premium Plan** ($39.99).
#### Calculation:

|| $19.99 + ($39.99 - $19.99) × (15/30) = $19.99 + $10.00 = $29.99

Your invoice will reflect two charges:
* $19.99 for the Advance Plan
* $10.00 for the upgrade
If you upgrade **on the same day** your billing cycle starts, you’ll simply be charged the **full price of the new plan** (e.g., $39.99 for Premium).

# **II. Downgrade Plan**
When downgrading, Shopify will show a confirmation message. After confirming, you will **lose access to features** exclusive to the higher-tier plan.

When switching to a lower monthly plan, **Shopify will automatically apply a credit** for the unused portion of your current plan.
#### **Proration Formula:**

|| Credit = (current_plan_cost - new_plan_cost) × (remaining_days / 30)


#### **Example:**
* You're on the **Premium Plan** ($39.99/month) and downgrade to the **Advance Plan** ($19.99/month) on Day 15.
#### **Calculation:**

|| ($39.99 - $19.99) × (15/30) = $10.00

You’ll receive a **$10.00 credit**, automatically applied to your next app charge.
