My company has changed address but all of previous invoices are now showing the new address and not the old. Can I change this?

Thanks for bringing this up in the Community, LKT.

Once you change your company address in QuickBooks Online (QBO), it will automatically recognize the new address when you create invoices moving forward. However, old transactions address from previous invoices should not be changed.

Let's try using a Private Browsing or Incognito window to isolate this issue. Since your web browser keeps files in its cache and saves the pages you have previously visited, private browser is a good place to start the troubleshooting.

Below are the keyboard shortcuts that you can refer:

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

If this works fine with Private Browsing or Incognito window, go back to your original browser and clear the cache to make sure your browser functions more efficiently. Otherwise, you can try other supported browser to help narrow down the cause of this behavior.
