In this guide I'm going to be covering how to add a return address to your
labels and invoices.
For making changes to your Royal Mail Barcoded Labels return address please
see this guide:
How do I change the return address on Royal Mail 2D barcode labels
Step by step guide:
1. First of all hover over Settings and click
Company
2. Once the page loads click Edit in the Company details
section
3. You will then be taken to a form where you can fill in your companies
address (or return address if its different), once you have filled in the form
simply scroll to the bottom and click save.
The form
The save button

5. Once this has saved you can then print out your labels, invoices and
packing slips, and they will all display this address.
See below for an example:
Address at top of label

And there you have it you company's address as your return address.
