Hi there, @ana-propster-tec.

Thanks for dropping by the Community page. I want to make sure you’re able to add your credit card information in the Billing & Subscription tab.

To start with, make sure to open QuickBooks as master or company admin to make changes on the billing and subscription settings. Then, follow these steps to add the card details:

1. Go to the Gear icon, then select Account and settings.
2. Select the Billing & Subscription tab.
3. Click on Edit next to your payment method.
4. Update your credit card info.
5. Review the address for your credit card. It must be the same one that appears on your credit card statements.
6. Once done, select Confirm card or Save.

To learn more about adding or updating billing, payment, and subscription info in QuickBooks Online, you can check out this article.

Just in case you're still unable to add the card when logging in as a master admin, I would like to know the error message you've received. This way, I can gather enough resources and share with you the right amount of information.

Let me know if you have any other QuickBooks or billing questions. I'm a few clicks away to help. Thanks for coming, keep safe!

Hi Angelyn, thank you so much for your email. We have tried to do everything that you have said and solve the problem with the card, but it is still not working. 

I am sending you a screenshot of the message we are getting every time when we try to add our card.
