Custom Header + conditionnal text

Hi,

I’m trying to modify the header from the PDF invoice but I didn’t manage to do it in the customizer tab.
Actually I have this : https://snipboard.io/0dAt4p.jpg
And I’d like to have this : https://snipboard.io/CA1ezH.jpg

Is that possible?

Also, as I do only B2B and international business, I need to put on invoices that have at least 1 product sold with 0% VAT this therm “Autoliquidation”. Do you have a way to do that or the easiest way is to add a text in the footer telling that if there is at least 1 product with 0% VAT it’s an autoliquidation?

Thanks
