Will I be charged for app fees if I pause my store?
If you are planning to use the Pause and Build plan in your store, please note that Shopify will continue charging you for app subscriptions.
On the other hand, if you're considering to go to the complete Pause plan, the app charges are paused when you pause your store. If you have any pending app charges, then you're billed for those charges when you pause your store.
Please visit the Shopify article about Pausing or Closing your Store for additional details.
