Hey, @Austinbork !
Thanks for joining this thread! As mentioned by Bo above, you cannot deactivate the store until the outstanding balance is paid. Once it has been paid, then you’ll have the option to deactivate your store by following the steps outlined here.
If you missed paying your Shopify subscription bill or if a payment fails multiple times, then your store is frozen until you settle your bill with Shopify. You can learn more here at the link.
