# Billing

* Supports both **monthly and annual billing intervals**.
* All subscriptions are managed through **Shopify’s native subscription billing system**.
* Charges appear directly on the store’s Shopify invoice.
* Plan changes (upgrades or downgrades) are handled through the **Manage plan** page.
* Development stores use **Free plan limits** (including AI credits), regardless of selected paid plans, until converted to a paid Shopify store.
