How do I edit an invoice template when the option is missing from my menu and a link via help says the page I requested cannot be found?

Hello, Dr. Jeff, and welcome to the QuickBooks Community forum. I'm here to assist you in successfully updating your bank details. 
 

Since you mentioned that the option is missing from your menu, could you please share the specific steps you have tried so far? This information will help me better understand the issue and provide more accurate assistance.

While waiting for your response, we can modify the invoice template can be one by going to the Gear icon and picking the Custom form styles.   

Once done, continue with these steps.

1. Choose the invoice template you want to edit.
2. In the Content tab, select the pencil on the bottom right to edit the footer section.
   
3. In the Add payment details and footer section, update the bank details.
4. Hit Done to reflect the changes.
   

However, if you followed the same steps I mentioned above and couldn't locate the Custom form style feature, and considering that the other page is not functioning correctly, we can take some steps to identify and isolate the cause of this issue.

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge & Mozilla Firefox: Ctrl + Shift + P
• Safari: Control + Option + P

If it works, return to your regular browser and clear its cache. You can also use a different browser like Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari.
