# App billing cycle

When using apps through Shopify, including Opus, it's important to understand how **app billing cycles** work so you can manage your charges and subscriptions effectively.
This guide will walk you through how Shopify handles billing for third-party apps, what to expect on your invoice, and how billing cycles relate to your Shopify subscription.

# What is an App Billing Cycle?
An **app billing cycle** is the interval at which you are charged for using a third-party app on your Shopify store. Shopify manages billing for most apps (including Opus), so your app charges are added directly to your Shopify invoice.

### Key Points:
* App billing cycles **do not necessarily match** your Shopify subscription billing cycle.
* Each app you install may have its own **billing cycle**, which usually starts on the day you approve the app charge.
* Charges are typically **recurring monthly**, but apps can also use **usage-based** or **one-time** charges.
---
# Types of App Charges
There are three main types of charges you may see from an app:
1. **Recurring Application Charges** (most common)
* A flat monthly fee — for example, **$12.99/month for Opus Basic plan**.
* Billed every 30 days starting from the approval date.
* Automatically renews unless canceled.
2. **Usage Charges**
* Based on how much you use the app (e.g., based on orders, views, or other metrics).
* These are **added to your invoice** within your Shopify billing cycle.
3. **One-Time Charges**
* A single charge, typically for a special feature, upgrade, or add-on.
* Billed once and not repeated unless explicitly triggered again.

# Billing Timeline Example
Let’s say you install an app on May 20 and approve a $12.99/month recurring charge:
* Your first app billing cycle is **May 20 – Jun 19**.
* You’ll be charged $12.99 on your **next Shopify invoice**, even if your main Shopify subscription renews on a different date.
* On Jun 19, the next $12.99 will be billed, starting a new 30-day app billing cycle.
**Please note:** App billing cycles and your Shopify billing cycle **may not always align**. This means charges can occasionally appear larger than expected, especially if **Shopify combines multiple app billing periods** (e.g., two months of charges) into a single invoice.

# Where to See App Charges

You can review all app charges directly in your **Shopify Admin**:
1. Go to **Settings > Billing**.
2. View your **current and past invoices**.
3. App charges are listed as line items under **App Charges** or **App Usage Charges**.
