How can i change some of the sub headings

I hope you're doing well, laushanrolle30-h.

I got the steps to help you change the sub-headings. Before we start, are you referring to the invoice? 

If so, you can select the header section to customise what displays. Let me show you how to do it.

1. Go to Settings ⚙, choose Custom form styles.
2. Find the template, then click Edit.
   
3. Click the Content tab, then select the pencil icon from the header section.
   
4. From there, you'll be able to customise the data that you want.
5. Click Done to save the changes.

If you need to enter additional data that isn't on the form, click the Manage custom fields link. 

Aside from customising the header, you can also change other fields or add a logo to the sales form. I'm adding these articles for instructions and detailed steps.
