Almost! The credit card will be billed for any Shopify-related charges. For example, the card will be charged every month for the Shopify subscription. You may also be charged for any apps you install or any shipping labels you may create. The funds your store generates can not go towards the monthly invoice as they will need to be paid separately.
Wishing you the best with it all and like I said if you have any other questions about Shopify or setting up your store. Don’t hesitate to ask.
