Hello, @Mori3.

Welcome to the Shopify Community.

Thanks for sharing your question. In order to investigate further, are you able to share more details about the issue you're experiencing? 

Could you provide information on the following:

• Are you having difficulties adding a payment method to pay for your Shopify bill?
• What error messages (if any) are you seeing on your end?
• If you're adding a payment method for your Shopify bill, does it fit the criteria for the card types we accept? You can find more information in our Billing FAQ.

The more information we're able to collect, the better we can support you and work together to have this resolved.

I look forward to your reply!
