Changing Invoice Format

I’ve been trying to figure out how to change the Invoice format. I have the original pdf that I have now modified but can’t figure out where to upload it. When I asked before I was provided with this link (https://documentation.vin65.com/Content-Editor/General-Pages/Page-Properties/Inserting-PDFs) but this only tells me how to upload and insert pdf’s. It doesn’t tell me where I need to upload or connect this updated Invoice receipt format.

I know you need to add this link to settings>website settings>store>Invoice PDF watermark.

Can anyone help explain the complete process?

That link is addressing how you upload a PDF to be hosted on your website. It doesn’t have anything to do with the invoice format. What exactly are you trying to change on the invoice/receipts?

I already have the new formatted invoice and create a new pdf. I just need to know where I need to upload it so that I can then add this link to this spot:

settings>website settings>store>Invoice PDF watermark

I believe you put the URL of the PDF in there once you have uploaded it.
