My address is showing up wrong on my invoices. I've changed and saved it to the correct one in the settings but it won't change on the invoices or quotes

Hi there, 

Welcome to the Community! QuickBooks Online offers a flexible program that allows you to customize your invoices so they show the correct address. I'll be happy to show you how to edit the wording on your invoices. 

You can add a custom message on your invoice  by clicking on the Gear icon > Custom Form Styles > open the receipt template in question > navigate to the Content tab > on the invoice image, click on the section with the address >  from here you can make necessary edit required for that invoice. You can follow the same steps for your estimates as well.

Here's a helpful article that shows you how to:
