Hello there, @osubucknutz.

Thank you for letting us know that the authorization form link is broken. I've also checked it on my end, and it is unavailable. But don't worry, I'll make sure you can get a signed authorization form so you can process online payments for invoices.

Our product engineers may be updating the authorization form link that's why it isn't available within your QuickBooks account or from the article. In this case, I'd recommend contacting our QuickBooks Payments Team. They may have an alternative way to get a signed authorization form so you can start processing invoice payments online.

To reach them, you can use the chat link or call the phone number provided in this article: Contact Payments Support.

You may need more information about accepting electronic customer payments for online invoices. This article will guide you through the process: Take and process payments in QuickBooks Online with QuickBooks Payments.

Our Community forum is always open to help you again if you need more assistance processing payments in QuickBooks Online. Wishing you all the best!
