Hello there, @belka1987m-gmail. I'll be sharing some troubleshooting steps to help you isolate the issue while subscribing to QuickBooks Online (QBO).
The error code 81624 usually occurs due to a failed payment authorization. The possible reason for this is an invalid address or the details entered didn't match with the financial institution. Ensure everything is correct.
If everything is correct and the error persists, I suggest logging into your QBO account via an incognito/private window. The browser's cache may be full, and using a private browser can help us determine if this is the cause of the issue.
Here are the keyboard shortcuts:
- Safari: Command + Shift + N
- Google Chrome: CTRL + Shift + N
- Mozilla Firefox or Microsoft Edge: CTRL + Shift + P
Once signed in, go back to your Account and Settings page and you can subscribe to QBO. When you've successfully done it, go back to your regular browser and clear its cache. Clearing the cache or cookies is the best way to get a clean slate for your browser.
Though, if private browsing doesn't work, I recommend using other supported browsers. They'll provide the best and most secure experience with QuickBooks.
Also, there might be other reasons why you encountered the error message. Check out the details under the Troubleshooting section of this article: Update billing, payment, and subscription info in QuickBooks Online.
I'll always have your back whenever you need help subscribing to QBO. Just tag me in your reply and I'll get back to you as soon as possible. Have a wonderful day!
