I'm here to collaborate with you and provide information to ensure that your customers successfully sign the form, atexshredding1.

The link is already working. I logged in to the Merchant Services site and I was able to download the authorization form. 

There are times that excessive cache and other browser-related issues can lead to QBO's improper functionality. To check if that's the case, I'll give you the steps that can effectively resolve these issues.

To begin, you have the option to try different browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari. QBO performs optimally with these browsers and can assist us in identifying the issue. 

You can also use these keyboard shortcuts to switch to an incognito browsing session which can also help us resolve browser issues:

• Ctrl + Shift + N for Google Chrome
• Ctrl + Shift + P for Firefox
• Control + Option +P if you're using Safari
• Ctrl + Shift + P for Microsoft Edge

After that, go back to the website and check if you can download the form. You can also go to this thread where you can download the form in a PDF format: https://quickbooks.intuit.com/learn-support/en-us/payments/ach-payment-authorization-form/00/1122372....

If everything is working fine,  follow the steps in this article on how to clear cached or delete internet files; Clear Cache and Cookies to Fix Issues When Using QuickBooks Online.
