I'd like to provide more information about why your virtual card was declined, Atxgutters.
Please note that a declined virtual card can be caused by a variety of reasons, including over-the-limit spending and incorrect billing information.
If you're using Green Dot, I recommend reaching out to their support team. They can review your account and provide the exact details of why your card was declined. You can contact them through the phone number located on the back of your card.
Additionally, you can refer to this article to learn more about possible reasons your card was declined: Credit card declined for QuickBooks Online subscription.
You can also connect your bank account to your account at any time, so your transactions will automatically download and categorize in QBO.
If you have further concerns, let me know. I'll be here to help you all way.
