How may I add an attachment to a PayPal invoice?

[Grimreepr · Accepted solution]

When you create the invoice, down towards the bottom there is something that says "more Options" to the direct right of that is a little drop down arrow, click on that.

A button should appear that says "upload files" under the heading of "attachments".
