I cant customise my invoice

I can help you in customising your invoices, @kmarble-stoneben.

Can you share with me the information that you're trying to edit and the error you're having? That'll help us get the best resolution for the error you're having.

In the meantime, I suggest clearing your browser's cache. There are times that the browser you're using has information stored that's stopping or causing the error when customising your invoices. 

First, you'll have to sign in to your QBO account using a private browser. This helps isolate the issue since it doesn’t store data in the cache. Here are the following keyboard shortcuts: 

• Safari: Command + Shift + N
• Mozilla Firefox: CTRL + Shift + P
• Google Chrome: CTRL + Shift + N 
• Microsoft Edge:  CTRL + Shift + P

If it works, here's how to clear cache and cookies to fix issues when using QuickBooks Online. Restart your browser right after. You can also proceed by using other browsers if the steps above don’t work.
