The invoice address is set up in the company's settings, Adamasprague-yah.
Let me guide you with changing it. Here's how:
Click the Gear icon.
Select Account and settings.
Go to the Company tab.
Click the Pencil icon in the Address section.
If the Customer-facing address is the same as the Company address, then change the info in the Company address field. If they're not the same, then you can change the info in the Customer-facing address field.
