Changing the address displayed on your invoices is done in your work info, Sam.
Here's how:
- Login to your QuickBooks Self-Employed (QBSE) account and select the Invoices tab on the left hand side.
- Choose Create invoice on the right hand side.

- At the bottom of the page, in the middle, you will see Edit Work Info, click it and edit your address there and then click on Save.


If you want to add a logo on your invoice, this can be done in your work info as well. Please note that the allowed file size is only 3 MB.
I've also attached an article on how to categorise transactions in QBSE which will help you organise your income and expenses so you know what areas of your self-employed business have the biggest impact.
Revisit the thread if you have more questions regarding your invoices.
