Cannot Edit Invoice Template in Online Quickbooks

Hello, tingeydr. Let's work together so you can start personalizing your invoice templates.

It is possible that the issue you're currently experiencing is caused by outdated or corrupted internet files, which is why the page isn't fully loading.

To isolate this problem, we can perform troubleshooting steps starting by accessing your QuickBooks Online account through a private/incognito window.

Depending on your browser use the keyboard shortcuts below:

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

If everything looks good, you can return to your regular browsing window and clear its cache. This will remove any outdated and corrupted temporary internet files that causes minor browsing issues. I've also added this article for additional information and scenarios: QuickBooks Online doesn't load correctly or has blank pages.

As an alternative, you can use other supported browsers to get the best and most secure experience while working in QuickBooks Online.

Let us know how it goes or if you still need further assistance about customizing invoices and other sales forms. I'll get back to you as soon as I can. Take care!
