Hi Peter,

Thanks for joining the thread. I can see how important to be able to keep your QuickBooks Online subscription active to continuously manage your books. 

Let's try to update your company address in your QBO file and match the billing address of your card. Here's how:

1. Click on the Settings icon in QBO.
2. Click on Company Settings.
3. Click on Address and enter the billing address of your card. Note: Do not enter special characters in your address.
4. Click on Save.

Once done, let's go back to the Subscriptions & Billing page to re-enter the payment information. Verify if payment went through successfully.

If the issue persists, I recommend contacting our Customer Care Team. That way, they can check your account in a secure form. 

Drop by again in the Community if you have other QBO concerns.
