Hi martindube-mdren,

Glad to have you reach out to the Community. QuickBooks provides an easy-to-use interface that makes it easy for you to make changes to your account. I'll be happy to show you how to set up your new business credit card in QuickBooks. 

If you're referring to the card you use for your subscription payments, here's how:

1. Log in to QuickBooks Online as a primary admin.
2. Click on Settings ⚙, then Account and settings.
3. Navigate to Billing & Subscription.
4. Next to your payment method, hit Edit ✎.
5. Update your credit card info.
6. Ensure the address in QuickBooks is the same as the one on your credit card statement.
7. Once you've made the appropriate changes, click on Confirm card or Save.

There you go, you now know how to update your subscription payment method. If you're referring to updating your bank/credit card, I encourage you to check out this helpful article here. The article does a great job elaborating on how you can connect your new business credit card.
