I'm here to guide you with changing your company address in QuickBooks. It seems you've already listed the correct address on your Account and Settings page. You can review it by following the steps below.
Go to the Gear icon, then select Account and Settings.
Pick Company from the left panel.
Click the Address pencil icon and check the Company address.
Next, you'll need to go to your default invoice template and update the company address. Here's how:
Go to the Gearicon, then select Custom Form Styles.
Locate your default template and click the Edit option.
Select the Content tab and click the upper portion of the invoice.
Change the address by clicking the + Address link.
Click Done once you're finished.
Please note that this change won’t affect those previously created invoices. It will only be applied moving forward. You can open the old transactions, and manually change the template used.
Once you complete the process, your new address should now show on your invoices.
