Good morning,
Hey there, Yetundeb1. I can share some information regarding the error you're getting and help you sort this out.
Error Code 81624 means that the payment authorization failed. This error usually occurs when you enter an invalid address or the details you've entered are not matching with the financial institution.
To fix this, you need to ensure everything is correct. You might want to coordinate with your card provider to verify the details.
I'm also adding the steps on how to reach our QuickBooks Online Support if you continue to have the error. They will be able to dive into your account and share your screen, to determine exactly what's going on and investigate further. Here's how to contact us:
1. Click the Help (?) icon.
2. Choose Contact Us.
3. Enter a brief description of your situation in the What can we help you with? area, then click Let's talk.
4. You'll be presented with a few options for connecting with Intuit. Select Get a call.
To learn more about changing your payment details, you can check out this article: Update Payment Information For Your Subscription.
Let me know how it goes by leaving a reply below. I want to make sure you're able to pay your QuickBooks Online account. I'll be right here if you need anything else. Have a good one!
