Hello, @GregMcPherson.

When creating projects in QuickBooks Online, there's no field for address, thus, we're unable to have a project address when creating invoices. At this time, you can manually update the address from the Ship To column. Also, I encourage following the steps provided above so our engineers will be updated about this feature.

As always, feel free to visit our blog to stay current with our latest QuickBooks updates.

You can always visit us here if you have any other concerns. I'm here to help. Keep safe!
