Company details doesn't appear on invoice

When creating a company I added al the details such as email and invoice. However, I can’t seem to find where to make sure these are added to documents. I have been to setup-printing but haven’t come across the setting there unless I want to readd all the details there

Can you post a screenshot of what you’re trying to do?
Try setting up a new Letter Head (with company name, etc) and select it in your print format.
